Outline

Sodium methanolate is one of alkoxides that are generated by methanol. Its chemical formula is CH3ONa. It is strong base that is commonly used in organic synthesis. Sodium methanolate is often stored in methanol, ethanol or the like alcohol solvent. It can generate suspension when it dissolves in ether. It can decompose into methanol and sodium hydroxide with water: CH3ONa + H2O→CH3OH + NaOH Sodium methanolate product has two forms: solid and liquid. Solid is pure sodium methanolate. The liquid is methanol solution of sodium methanolate and the content of sodium methylate is 27.5% to 31%. Liquid sodium methanolate is colorless or slightly yellow viscous liquid. It is sensitive to oxygen. It is flammable, explosive and easily hygroscopic. It is soluble in methanol and ethanol, and can decompose into methanol and sodium hydroxide with water. It decomposes at 126.6℃ in the air. It is not soluble in benzene and toluene. It is strong irritant and highly corrosive. Sodium methanolate can be used as condensing agent, strong alkaline catalyst and methoxy agent for the preparation of vitamin B1, vitamin A, sulfadiazine and other drugs. Few can be used in production of pesticides. It can also be used as catalyst in processing edible fats and oils (especially processing lard). It is used as analytical reagent. Solid sodium methanolate is colorless amorphous powder. It is sensitive to oxygen, and it is flammable. It is soluble in methanol and ethanol, and can decompose into methanol and sodium hydroxide with water. It decomposes at 126.6℃ in the air. It is mainly used for the production of sulfa drugs, VB6 and VA. Sodium methylate is a kind of catalyst for organic synthesis. It can be used for the production of pesticides and oil processing industries. Solid sodium methanolate and sodium methoxide methanol solution Sodium methylate is a kind of mature chemical products. It has several decades of production history in China. The overall price is high in the south than in the north. Its price is 4500 yuan/T in the southwest, and 4,000 yuan/T in Shandong. Its price changed little with the increase of methanol’s price in 2004. The profit of per ton of product is 500 to 700.

Soda process for producing sodium methylate

Sodium methylate is prepared by the reaction of methanol with sodium hydroxide for soda method. Their reaction is as follows: CH3OH + NaOH→CH3ONa + H2O 1. The preparation of methanol lye Crush the solid sodium hydroxide. Then add it into melting pot base containing methanol (99.8%) in proportion. Start circulating pump, and dissolve the sodium hydroxide below 70℃. When its content is 20% to 23%, cool down to 40℃ and inject into the settling tank. Stand 12h and spare. 2. The preparation of sodium methylate Pass into the steam to the vaporization pot and reaction tower mezzanine. Heat it and control the temperature at 85~100℃. Add anhydrous methanol to vaporization pot at the flow rate of 180L/h. Meanwhile add methanol lye in the top of the reaction tower at the flow rate of 25kg/h. Methanol gas containing 2% of water produced by the reaction from the reaction distill the reaction tower overhead into the purification distillation column to remove water. Then it becomes absolute methanol recycling. Control the temperature of reaction bottoms (i.e. vaporization pot) at 65~70℃, and check the bottoms. When containing 27%~31% Sodium methanolate, 1% or less of the free base, products are obtained. The yield is 86% (as sodium hydroxide). Fixed consumption of the process is as follows: methanol (95%) 973kg/t, sodium hydroxide (99.5%) 209kg/t. The above information is edited by the lookchem of Ge Qian.

Sodium process for producing sodium methylate

Sodium metal and methanol as raw materials, using intermittent production process to produce methanol solution of sodium methylate. The reaction is as follows: 2CH3OH + 2Na→2CH3ONa + H2↑ The production process is mainly divided into four parts: 1. Feeding step. Industrial methanol is pumped into methanol metering tank. 120kg of sodium metal is added into the reaction kettle. 2. Nitrogen substitution step. Close feed valve and vent valve. Purged with nitrogen into the reactor so that the index reached 0.1MPa. Open vent valve to remove the pressure, and repeat three times under reflux. The vent valve remains open to continue introducing nitrogen. 3. Reaction step. The cooling water is fed to the condenser. Methanol is immediately added to the methanol tank (note methanol addition rate). Nitrogen is stopped after 5~10min. Methanol is continuously added. 820kg of methanol is added in 2~3h and then the feed valve is closed. The reaction is continued for 2~3h until the reaction mixture has no bubbles. 4. Reconciliation step. The product is added into the harmonic tank. Sample and analysis. Reconcile to the desired concentration and barrels.

The comparison soda process with sodium process

The content of methanol alkaline get by sodium method is higher, more reliable and stable than alkaline method. And the content of free alkali is low. Sodium methylate prepared by sodium method can take off a lot of alcohol and other impurities from sodium in the reaction. The content of Na2CO3 in sodium method is lower than in alkaline method, which can improve product quality and yield of the users.

Solution quality reference standard

Item Index Appearance colorless to pale yellow viscous liquid Content (total base number) 29.5%~31.0% Sodium methoxide (NaOCH3) 28.9%~31.0% Sodium hydroxide (NaOH) ≤0.5% Sodium carbonate (Na2CO3) ≤0.1% Water (H2O) ≤0.2% Methanol 69.0%~70.7%

How to separate solid sodium hydroxide and sodium methylate

1. Dissolved in water (sodium alcoholate reacts violently with water to generate alcohol and sodium hydroxide) 2. Distillation (separate alcohol) 3. Evaporation (separate sodium hydroxide) 4. Try to dry alcohol to anhydrous state (repeated distillation) 5. Add sodium to generate sodium alcohol 6. Distill alcohol to get solid alcohol sodium. (It should be avoided being exposed to the air when distilling. If it is exposed to the air or it is taken down before drying up and cooling, the state of alcohol sodium that is separated out is not well. The good one is white. if not, it will be tan is. But it doesn’t have any great impact. It is easy to be prepared.)

Production Process

Solid sodium hydroxide and methanol mix at a certain proportion. After stirring the mixture to dissolve, solid impurities are removed by sedimentation and clarification. The clear liquid is pumped into the top of the dehydration reaction column, while the refined methanol vapor is added from the bottom of the tower with continuous dehydration reaction. Then the product can be obtained from tower bottom. Aqueous methanol vapor is purified from the top of the column into the distillation system, while anhydrous methanol can be used repeatedly.

Identification test

It can react with oxygen and carbon dioxide. It decomposes in water. Sodium test of the solution (IT-28) is positive. Take 0.1m1 5% sulfuric acid and 0.2ml potassium permanganate solution (TS-193), and add 1 drop of 1% aqueous solution of the sample. After placing 5min, add 0.2ml 25% sodium sulfite solution and 3ml sulfate. Then add 0.2ml chromium changed acid solution (TS-l66). The solution is amaranth to purple.

General Description

Sodium methylate is a white amorphous powder. It reacts with water to form sodium hydroxide, a corrosive material, and methyl alcohol, a flammable liquid. The heat from this reaction may be sufficient to ignite surrounding combustible material or the sodium methylate itself if the water is present in only small amounts. It is used to process edible fats and oils, and to make other chemicals.

Air & Water Reactions

Highly flammable. Ignites in moist air [Wischmeyer 1966]. Reacts with water to produce a mixed solution of sodium hydroxide and methyl alcohol.

Reactivity Profile

SODIUM METHYLATE is a strong base. Reacts with light metals forming H2 gas, with fire and explosion hazards. Too rapid addition of sodium methylate to a mixture of chloroform and methanol initiated an uncontrolled exothermic reaction between the chloroform and the methylate that caused a violent explosion [MCA Case History 693 1961]. Sodium methoxide is incompatible with 4-chloronitrobenzene and fluorinated cyclopropenyl methyl ethers, such as perfluoromethoxycyclopropene. The reactions are vigorous and may initiate ignition [Bretherick, 1995, pg. 191].

Hazard

(Solid) Flammable when exposed to heat or flame. (Solution) Flammable, moderate fire risk.

Health Hazard

TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Fire Hazard

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.

Flammability and Explosibility

Flammable

Safety Profile

A corrosive and irritating material. It hydrolyzes into methanol and sodlum hydroxide. May ignite spontaneously in moist air. Flammable when exposed to heat or flame. Ignites on contact with water, Violent reaction with (CHCl3 + CH3OH), (methyl azide + dimethylmalonate), FClO3. When heated to decomposition it emits toxic fumes of Na2O.

Purification Methods

It behaves in the same way as sodium ethoxide. It is hygroscopic and is hydrolysed by moist air to NaOH and MeOH. Material that has been kept under N2 should be used. If erratic results are obtained, even with recently purchased NaOMe, it should be freshly prepared thus: Clean Na (37g) cut in 1-3g pieces is added in small portions to stirred MeOH (800mL) in a 2L three-necked flask equipped with a stirrer and a condenser with a drying tube. After all the Na has dissolved, the MeOH is removed by distillation under vacuum, and the residual NaOMe is dried by heating at 150o under vacuum and kept under dry N2 [Burness Org Synth 39 51 1959]. [Beilstein 1 IV 1227.]

Broensted Acidities of Carbonyl Hydride Complexes of Iron, Ruthenium, and Osmium: pKa Values and Deprotonation Rates in Methanol Solution

Walker, Howard W.,Pearson, Ralph G.,Ford, Peter C.

, p. 1179 - 1186 (1983)

Reported are kinetics studies of the reaction of methoxide ion with several mononuclear and polynuclear carbonyl hydride complexes HxMy(CO)z of the iron triad.Deprotonation of the hydrides to give the conjugate base anions occurs with moderate second-order rate constants (ca. 101-104 M-1s-1), considerably smaller than those of oxygen or nitrogen acids of comparable thermodynamic strength under similar conditions.The relative slowness of these reactions is interpreted in terms of possible electronic and structural rearrangements of substrate and solvent occuring as the result of the deprotonation.In addition the kinetics technique allows the measurement of the reverse reacton (protonation of the conjugate base by methanol) rate constants which are also comparatively small (ca. 0.05-25 s-1).The ratio of the forward and reverse rates gives the equilibrium constants from which the pKa's in methanol can be calculated.In several cases pKa's were confirmed by buffer/indicator techniques.From these and other published data are drawn the conclusions that bridging hydrides are more acidic than terminal hydrides and that hydrides of the lighter metals are more acidic than those of homologous heavier metals.Furthermore, it is shown than the substituent effect of replacing CO of a cluster by a trimethyl phosphite is to decrease significantly the acidity of that cluster's hydrides.

Kinetic Studies on the Decomposition of Most Typical Meisenheimer Complex of Sodium 1,1-Dimethoxy-2,4,6-trinitrocyclohexadienide in Methanol

Abe, Takehiro

, p. 1399 - 1405 (1980)

The whole decomposition of the Meisenheimer complex formed from 2,4,6-trinitroanisole (TNA) and sodium methoxide proceeds in three steps and obeys the first-order kinetics in each step.The rate of the whole decrease of concentration of the complex is given by -d(+->)/dt=(k1+>+k2)*+(k3+>+k4)*->-k5->*, where k denotes a rate constant.This leads to the modification of the conventional unimolecular mehanism shown by TNA*CH3O- -> TNA +CH3O-.

Standard molar enthalpies of formation of sodium alkoxides

Chandran,Srinivasan,Gopalan,Ganesan

, p. 449 - 454 (2007)

The molar enthalpies of solution of sodium in methanol, ethanol, and n-propanol and of sodium alkoxides in their corresponding alcohols were measured at T = 298.15 K using an isoperibol solution calorimeter. From these results and other auxiliary data, the standard molar enthalpies of formation Δf Hm{ring operator} (RONa,cr) of sodium methoxide, sodium ethoxide, and sodium n-propoxide were calculated and found to be {(-366.21 ± 1.38), (-413.39 ± 1.45), and (-441.57 ± 1.18)} kJ · mol-1, respectively. A linear correlation has been found between Δf Hm{ring operator} (RONa) and Δf Hm{ring operator} (ROH) for R = n-alkyl, enabling the prediction of data for other sodium alkoxides.

Synthesis and evaluation of the cytotoxic activity of water-soluble cationic organometallic complexes of the type [Pt(η1-C2H4OMe)(L)(phen)]+ (L = NH3, DMSO; phen = 1,10-phenanthroline)

De Castro, Federica,Stefàno, Erika,Migoni, Danilo,Iaconisi, Giorgia N.,Muscella, Antonella,Marsigliante, Santo,Benedetti, Michele,Fanizzi, Francesco P.

, (2021)

Starting from the [PtCl(η1-C2H4OMe)(phen)] (phen = 1,10-phenanthroline, 1) platinum(II) precursor, we synthesized and characterized by multinuclear NMR new [Pt(η1-C2H4OMe)(L)(phen)]+ (L = NH3, 2; DMSO, 3) complexes. These organometallic species, potentially able to interact with cell membrane organic cation transporters (OCT), violating some of the classical rules for antitumor activity of cisplatin analogues, were evaluated for their cytotoxicity. Interestingly, despite both complexes 2 and 3 resulting in greater cell uptake than cisplatin in selected tumor cell lines, only 3 showed comparable or higher antitumor activity. General low cytotoxicity of complex 2 in the tested cell lines (SH-SY5Y, SK-OV-3, Hep-G2, Caco-2, HeLa, MCF-7, MG-63, ZL-65) appeared to depend on its stability towards solvolysis in neutral water, as assessed by NMR monitoring. Differently, the [Pt(η1-C2H4OMe)(DMSO)(phen)]+ (3) complex was easily hydrolyzed in neutral water, resulting in a comparable or higher cytotoxicity in cancer cells with respect to cisplatin. Further, both IC50 values and the uptake profiles of the active complex appeared quite different in the used cell lines, suggesting the occurrence of diversified biological effects. Nevertheless, further studies on the metabolism of complex 3 should be performed before planning its possible use in tissue- and tumor-specific drug design.

Two bis(dithiolato)nickel salts with different flexible ammonium counterions, [Et3MeN][Ni(dmit)2] (1) and [(i-Bu)Et3N][Ni(dmit)2] (2) (dmit2? = 2-thioxo-1,3-dithiole-4,5-dithiolate, Et3MeN+ = triethylmethylammonium, (i-Bu)Et3N+ = triethylisobutylammonium), are prepared and identified by powder X-ray diffraction (PXRD) patterns and single-crystal X-ray diffraction. Salt 1 crystallizes in the triclinic space group P???1 at 293?K. The anions and cations in 1 form alternating layered arrangements along the a-axis direction. Salt 2 belongs to the monoclinic crystal system and space group P21/n. The anions and cations in 2 form separate columnar stacks along bc-plane direction. The neighboring anions are stacked as dimers in the anion columnar stacks of 2. The magnetic features of salts 1 and 2 show 1D alternating spin chain magnetic exchange behavior, and the magnetic experimental data are well fitted through a spin chain magnetic model. The difference in the crystal structures and magnetic properties between the two new salts 1 and 2 fully demonstrates that the magnetic properties are dependent on the alignment of the [Ni(dmit)2]? anions, which are related to the flexible organic cations.

Chemical transformations and biological studies of terpenoids isolated from essential oil of Cyperus scariosus

Sharma,Utreja,Bedi

, p. 2153 - 2158 (2016)

Cyperus scariosus is a potential medicinal herb belonging to the family Cyperaceae. The GC-MS analysis of the oil showed cyprene (18.57 %) as the major terpene present in it. Cyprene was isolated from the non-polar fraction of the oil using hexane as solvent and characterized using TLC and spectral techniques (IR and 1H NMR). Cyprene was derivatized to cyprene epoxide by two methods i.e. using perbenzoic acid and epichlorohydrin. Further, the oil, it's polar fraction (dichloromethane), non-polar fraction (hexane), cyprene and cyprene epoxide were screened for their plant growth regulating property in case of wheat seedlings (HD 2967 and PBW 621). Complete germination was observed above 2.5 μg/mL of all the test fractions in both the cultivars. Moreover, cyprene epoxide was found to be the most effective in enhancing the length of roots and shoots. Seedling vigour index was calculated in order to analyze the enhancement shown by the oil and its various components on the seedlings.

Three series of 4-hydroxy-N′-[benzylidene/1-phenylethylidene]-2-H/methyl/benzyl-1,2-benzothiazine-3-carbohydrazide 1,1-dioxides (9–11)a-l were synthesized and unraveled to be highly potent dual inhibitors of monoamine oxidases (MAO-A and MAO-B). All the examined compounds demonstrated IC50 values in lower micro-molar range for both MAO-A as well as MAO-B. The most active MAO-A inhibitor was 4-hydroxy-N′-(1-phenylethylidene)-2H-benzo[e][1,2]thiazine-3-carbohydrazide 1,1-dioxide (9i) with an IC50 value of 0.11 ± 0.005 μM, whereas, methyl 4-hydroxy-2H-benzo[e][1,2]thiazine-3-carboxylate 1,1-dioxide (3) was the most active MAO-B inhibitor with an IC50 value of 0.21 ± 0.01 μM. Enzyme kinetics studies revealed that the most potent compounds inhibited both MAO enzymes (A & B) in a competitive fashion. Molecular docking studies were also performed to obtain an intuitive picture of inhibition potential for potent inhibitors. The high potency of these compounds is optimally combined with highly favorable ADME profile with predicted good oral bioavailability.

A nickel-catalyzed 1,2-diarylation of alkenyl ketones with aryl iodides and arylboronic esters is reported. Ketones with a variety of substituents serve as effective directing groups, offering high levels of regiocontrol. A representative product is diversified into a wide range of useful products that are not readily accessible via existing 1,2-diarylation reactions. Preliminary mechanistic studies shed light on the binding mode of the substrate, and Hammett analysis reveals the effect of electronic factors on initial rates.
