Uses

Isopropyl alcohol is used in the production of acetone, isopropyl halides, glycerin, and aluminum isopropoxide; employed widely as an industrial solvent for paints, polishes, and insecticides; as an antiseptic (rubbing alcohol); and in organic synthesis for introducing the isopropyl or isopropoxy group into the molecule. Being a common laboratory solvent like methanol, the exposure risks are always high; however, its toxicity is comparatively low.

Safety

Isopropyl alcohol is widely used in cosmetics and topical pharmaceutical formulations. It is readily absorbed from the gastrointestinal tract and may be slowly absorbed through intact skin. Prolonged direct exposure of isopropyl alcohol to the skin may result in cardiac and neurological deficits. In neonates, isopropyl alcohol has been reported to cause chemical burns following topical application. Isopropyl alcohol is metabolized more slowly than ethanol, primarily to acetone. Metabolites and unchanged isopropyl alcohol are mainly excreted in the urine. Isopropyl alcohol is about twice as toxic as ethanol and should therefore not be administered orally; isopropyl alcohol also has an unpleasant taste. Symptoms of isopropyl alcohol toxicity are similar to those for ethanol except that isopropyl alcohol has no initial euphoric action, and gastritis and vomiting are more prominent; see Alcohol. Delta osmolality may be useful as rapid screen test to identify patients at risk of complications from ingestion of isopropyl alcohol. The lethal oral dose is estimated to be about 120–250mL although toxic symptoms may be produced by 20 mL. Adverse effects following parenteral administration of up to 20mL of isopropyl alcohol diluted with water have included only a sensation of heat and a slight lowering of blood pressure. However, isopropyl alcohol is not commonly used in parenteral products. Although inhalation can cause irritation and coma, the inhalation of isopropyl alcohol has been investigated in therapeutic applications. Isopropyl alcohol is most frequently used in topical pharmaceutical formulations where it may act as a local irritant. When applied to the eye it can cause corneal burns and eye damage.

description

Isopropanol is also known as isopropyl alcohol. It is the simplest secondary alcohol and is one of the isomers of n-propanol. It is a kind of flammable liquid which is colorless with strong smell being similar to the smell of the mixture of ethanol and acetone. It is soluble in water, alcohol, ether, benzene, chloroform and most organic solvents and is miscible with water, alcohol, ether and can form azeotrope with water. Density (specific gravity): 0.7863g/cm3, melting point:-88.5 ℃, boiling point: 82.5 ℃, flash point: 11.7 ℃, ignition point: 460 ℃, refractive index: 1.3772. Its vapor can cause slight irritation on the eyes, nose and throat; it can be absorbed through the skin. Its vapor can form explosive mixture with air. Its explosion limit is 2.0% to 12% (by volume). It belongs to a moderate explosive hazardous material and flammable, low toxic substance. The toxicity of its vapors is twice as high as ethanol while oral administration causes the opposite toxicity. Figure 1 is the structural formula of isopropanol. In many cases, isopropanol can substitute ethanol as the solvent and is a good solvent and chemical raw materials which can be applied to not only painting, pharmaceuticals, pesticides, cosmetics and other industries, but also the production of acetone, isopropyl ester, isopropylamine (the raw material for production of atrazine), di-isopropyl ether, isopropyl acetate and thymol crystal etc. It was the first product which is made from the petroleum raw material in the history of the development of petrochemicals.

Uses

In antifreeze compositions; as solvent for gums, shellac, essential oils; in the extraction of alkaloids; in quick-drying oils; in quick-drying inks; in denaturing ethyl alcohol; in body rubs; hand lotions, after-shave lotions and similar cosmetics. Solvent for creosote, resins, gums; in manufacture of acetone, glycerol, isopropyl acetate. Pharmaceutic aid (solvent).

Reactivity Profile

Isopropanol reacts with air or oxygen to form dangerously unstable peroxides. Contact with 2-butanone increases the rate of peroxide formation. An explosive reaction occurs when Isopropanol is heated with (aluminum isopropoxide + crotonaldehyde). Forms explosive mixtures with trinitromethane and hydrogen peroxide. Reacts with barium perchlorate to form a highly explosive compound. Ignites on contact with dioxygenyl tetrafluoroborate, chromium trioxide and potassium-tert-butoxide. Vigorous reactions occur with (hydrogen + palladium), nitroform, oleum, COCl2, aluminum triisopropoxide and oxidizing agents. Reacts explosively with phosgene in the presence of iron salts. Incompatible with acids, acid anhydrides, halogens and aluminum . Isopropanol can react with PCl3, forming toxic HCl gas. (Logsdon, John E., Richard A. Loke., sopropyl Alcohol. Kirk-Othmer Encyclopedia of Chemical Technology. John Wiley & Sons, Inc. 1996.).

storage

Isopropyl alcohol should be stored in a cool, dry, well-ventilated area in tightly sealed containers with a proper label. Outside or detached storage is preferable. Inside storage should be a flammable liquids storage room or cabinet. Workers should not store isopropyl alcohol above 37°C (100°F). Containers of isopropyl alcohol should be protected from physical damage and contact with air, and should be stored separately from strong oxidizers, acetaldehyde, chlorine, ethylene oxide, acids, and isocyanates. Isopropyl alcohol should be transported to the nearest laboratory as quickly as possible in cool containers.

Production Methods

Isopropyl alcohol may be prepared from propylene; by the catalytic reduction of acetone, or by fermentation of certain carbohydrates.

Uses

Isopropyl alcohol is an important chemical products and raw materials. It is mainly applied to various fields including pharmaceutical, cosmetics, plastics, fragrances, paint as well as being used as the dehydrating agent and cleaning agent in and electronics industry. It can also be used as the reagent for determination of barium, calcium, magnesium, nickel, potassium, sodium and strontium. It can also be used as the reference material of chromatographic analysis. In the manufacturing industry of circuit board, it is used as a cleaning agent, and the production of PCB holes for conductivity. Many people find that it can not only clean the motherboard with excellent performance, but also get the best results. In addition, it is used for other electronic devices, including cleaning disc cartridge, floppy disk drives, magnetic tape, and the laser tip of the disc driver of CD or DVD player. Isopropyl alcohol can also be used as the solvent of oil and gel as well as for the manufacture of fishmeal feed concentrate. Low-quality isopropanol can also be used in automotive fuels. As the raw material of production of acetone, the usage amount of isopropanol is reducing. There are several compounds which are synthesized from isopropanol, such as isopropyl ester, methyl isobutyl ketone, di-isopropylamine, di-isopropyl ether, isopropyl acetate, thymol and many kinds of esters. We can supply isopropanol of different quality depending on the end use it. The conventional quality of anhydrous isopropanol is more than 99%, while the special grade isopropanol content is higher than 99.8% (for flavors and drugs).

Also found in apple, banana, grapefruit and lime juice, melon, papaya, pear, onion, peas, rutabaga, tomato, wheat bread, cheeses, milk, boiled egg, cooked beef, pork and mutton, hop oil beer, rum, cocoa, coffee, scotch whiskey, grape wines, peanut, pecan, soybean, honey, beans, plum brandy, walnut, crab, clam, prickly pear and clary sage.

Regulatory Status

Included in the FDA Inactive Ingredients Database (oral capsules, tablets, and topical preparations). Included in nonparenteral medicines licensed in the UK. Included in the Canadian List of Acceptable Non-medicinal Ingredients.

Limited use

FEMA (mg/kg): soft drinks: 25; sweets: 10 to 75; baked good: 75.

Definition

ChEBI: A secondary alcohol that is propane in which one of the hydrogens attached to the central carbon is substituted by a hydroxy group.

Incompatibilities

Incompatible with oxidizing agents such as hydrogen peroxide and nitric acid, which cause decomposition. Isopropyl alcohol may be salted out from aqueous mixtures by the addition of sodium chloride, sodium sulfate, and other salts, or by the addition of sodium hydroxide.

Production Methods

Two basic methods of production are in commercial use: (1) absorption of propylene in sulfuric acid to form alkyl hydrogen sulfate, followed by the hydrolysis of the ester; and (2) by direct hydration with water, using a catalyst. An inherent disadvantage in the first process is the need to handle sulfuric acid. Further, the first process yields little more than 70% isopropanol as compared with the second process, in which liquid propylene is used as the charge stock. All direct-hydration processes can be represented by: C3H6 + H2O ??→ C3H7OH + heat.

Uses

isopropyl alcohol is a carrier, anti-bacterial, and solvent for skin care lotions. Isopropyl alcohol is made from propylene, a petroleum derivative.

Health Hazard

Exposures to isopropyl alcohol cause irritation to the eyes and mucous membranes. Exposures to isopropyl alcohol for 3–5 min (400 ppm) caused mild irritation of the eyes, nose, and throat, and at 800 ppm these symptoms became severe. Ingestion or an oral dose of 25 mL in 100 mL of water produced hypotension, facial fl ushing, bradycardia, and dizziness. Ingestion in large quantities caused extensive hemorrhagic tracheobronchitis, bronchopneumonia, and hemorrhagic pulmonary edema. Prolonged skin contact with isopropyl alcohol caused eczema and sensitivity. Delayed dermal absorption is attributed to a number of pediatric poisonings that have occurred following repeated or prolonged sponge bathing with isopropyl alcohol to reduce fever. In several cases, symptoms included respiratory distress, stupor, and coma. Laboratory animals exposed to isopropyl alcohol develop poisoning with symptoms of hind leg paralysis, unsteadiness, lack of muscular coordination, respiratory depression, and stupor. Isopropyl alcohol is a potent CNS depressant, and in large doses causes cardiovascular depression.

Precautions

Workers should wash hands and face thoroughly after handling isopropyl alcohol. Workers should wear gloves, safety glasses and a face shield, boots, apron, and a full impermeable suit is recommended if exposure is possible to a large portion of the body.

Pharmaceutical Applications

Isopropyl alcohol (propan-2-ol) is used in cosmetics and pharmaceutical formulations, primarily as a solvent in topical formulations.( It is not recommended for oral use owing to its toxicity. Although it is used in lotions, the marked degreasing properties of isopropyl alcohol may limit its usefulness in preparations used repeatedly. Isopropyl alcohol is also used as a solvent both for tablet film-coating and for tablet granulation, where the isopropyl alcohol is subsequently removed by evaporation. It has also been shown to significantly increase the skin permeability of nimesulide from carbomer 934. Isopropyl alcohol has some antimicrobial activity and a 70% v/v aqueous solution is used as a topical disinfectant. Therapeutically, isopropyl alcohol has been investigated for the treatment of postoperative nausea or vomiting.

Uses

Suitable for HPLC, spectrophotometry, environmental testing

Carcinogenicity

CD-1 mice were exposed by inhalation to 0, 500, 2500, or 5000 ppm of isopropanol vapor for 6 h/day, 5 days/week for 18 months. An additional group of mice (all exposure levels) were assigned to a recovery group that were exposed to isopropanol for 12 months and then retained until study termination at 18 months. There was no increased frequency of neoplastic lesions in any of the isopropanol-exposed animals. Nonneoplastic lesions were limited to the testes (males) and the kidney. In the testes, enlargement of the seminal vesicles occurred in the absence of associated inflammatory or degenerative changes. The kidney effects included tubular proteinosis and/or tubular dilatation. The incidence of testicular and kidney effects was not increased in the isopropanol-exposed recovery animals.

Uses

When compared to ethanol, 50% less is required for nucleic acid precipitation, thus minimizing the total volume to be centrifuged for DNA or RNA recovery.

Fire Hazard

HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.

Air & Water Reactions

Highly flammable. Water soluble.

Production Process

In 1855, Frenchman M. Berthelot first reported the production of isopropanol through the hydration reaction between propylene and sulfuric acid, called indirect hydration. In 1919, the Americans C. Ellis had conducted industrial development on this. At the end of 1920, the American Standard Oil Company of New Jersey adopted the approach of Ellis Act and established the production equipment for putting into formal production. In 1951, the British company Imperial Chemical Industries began to produce isopropanol with the direct hydration method from propylene. Since then, many countries have used this method and made related improvements. Indirect hydration reaction: propylene is first reacted with sulfuric acid to obtain isopropyl hydrogen sulfate, which generates isopropanol after hydrolysis, and the reaction of the formula: CH3CH = CH2 + H2SO4 → (CH3) 2CHOSO3H (CH3) 2CHOSO3H + H2O─ → (CH3) 2CHOH + H2SO4 the concentration of the applied sulfuric acid is generally greater than 60% (by mass), and the reaction is conducted at 2~2.8MPa and 60~65 ° C; The hydrolysis reaction happens at slight increased pressure and at below 30 ° C. Direct hydration: propylene directly has hydration reaction with water in the presence of a catalyst upon heating and increased pressure to generate isopropanol with a selectivity of 96%. Reaction is: CH3CH = CH2 + H2O → (CH3) 2CHOH; the used catalyst includes tungsten compound, phosphate and ion exchange resin; the commonly used catalyst is phosphoric acid catalyst with carrier (see solid acid catalyst) with conditions of 2~6MPa, 240~260 ° C. Compared with the indirect method, this method does not have issue regarding to sulfuric acid corrosion and dilute acid concentration and therefore, it dominant in industrial production. The above information is edited by the Chemicalbook of Dai Xiongfeng.

Purification Methods

Isopropyl alcohol is prepared commercially by dissolution of propene in H2SO4, followed by hydrolysis of the sulfate ester. Major impurities are water, lower alcohols and oxidation products such as aldehydes and ketones. Purification of isopropanol follows substantially the same procedure as for n-propyl alcohol. Isopropanol forms a constant-boiling mixture, b 80.3o, with water. Most of the water can be removed from this 91% isopropanol by refluxing with CaO (200g/L) for several hours, then distilling. The distillate can be dried further with CaH2, magnesium ribbon, BaO, CaSO4, calcium, anhydrous CuSO4 or Linde type 5A molecular sieves. Distillation from sulfanilic acid removes ammonia and other basic impurities. Peroxides [indicated by liberation of iodine from weakly acid (HCl) solutions of 2% KI] can be removed by refluxing with solid stannous chloride or with NaBH4 then the alcohol is fractionally distilled. To obtain isopropanol containing only 0.002M of water, sodium (8g/L) is dissolved in material dried by distillation from CaSO4. Isopropyl benzoate (35mL) is then added and, after refluxing for 3hours, the alcohol is distilled through a 50-cm Vigreux column (p 11). [Hine & Tanabe J Am Chem Soc 80 3002 1958.] Other purification steps for isopropanol include refluxing with solid aluminium isopropoxide, refluxing with NaBH4 for 24hours, and removing acetone by treatment with, and distillation from, 2,4-dinitrophenylhydrazine. Peroxides re-form in isopropanol if it is kept for several days in contact with air. [Beilstein 1 IV 1461.]
