95-45-4 Usage

Chemical Properties

Dimethylglyoxime is a white crystalline powder. Soluble in alcohol, ether, acetone and pyridine. Solubility in water 0.5g/l, insoluble in tolerate chloroform, toluene, xylene. It is one of the first selective organic reagents applied in analytical chemistry. It is an extraordinary sensitive and specific reagent for nickel. under appropriate conditions dimethylglyoxime is specific for nickel(II) and palladium(II), but it also forms coloured water-soluble complexes with iron(II), cobalt(II) and copper(II).

Uses

Different sources of media describe the Uses of 95-45-4 differently. You can refer to the following data:
1. Dimethylglyoxime is used as nickel-specific complexing reagent; determination of palladium.
2. Detection and determination of Ni and its separation from Co and many other metals. Forms a scarlet red ppt with Ni even in dil solutions. Separation of Pd from Sn, Au, Rh, and Ir, also to detect Bi with which it forms a bright yellow color and ppt.
3. Dimethylglyoxime is specific for nickel(II) ions in ammoniacal solution if alkali tartrate is employed as masking agent to keep in solution the possibly interfering hydrolysing salts.

Reactions

Nickel cation reacts with dimethylglyoxime forms an insoluble red precipitate of nickel dimethylglyoxime. Ni2+ + 2C4H8N2O2 → Ni(C4H7N2O2)2↓(red precipitate) + 2H+Dimethylglyoxime reacts with ferrous sulphate and ammonium hydroxide forms a complex compound of iron and ammonium sulphate and water is formed. FeSO4 + 2NH4OH + 2C4H8N2O2 → Fe(C4H7N2O2)2 + (NH4)2SO4 + 2H2O

General Description

Dimethylglyoxime (DMG) is a complexing ligand. Dimethylglyoxime forms a number of mixed ligand complexes with N-acetylglycine with metals such as VO(IV), Ni(II), Zn(II), Pd(II), Cd(II) and Pb(II). It is a useful reagent for the spectrophotometric determination of Co(II), Fe(II), Ni(II), Pd(II) and Re(VII).

Safety Profile

Poison by ingestion. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx.

Purification Methods

Crystallise it from EtOH (10mL/g) or aqueous EtOH. [Beilstein 1 III 3105.] TOXIC.

Check Digit Verification of cas no

The CAS Registry Mumber 95-45-4 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 95-45:
(4*9)+(3*5)+(2*4)+(1*5)=64
64 % 10 = 4
So 95-45-4 is a valid CAS Registry Number.

2D Ferromagnetic sheet of antiferromagnetic trimeric metal cores

Biswas, Susobhan,Saha, Rajat,Steele, Ian M.,Dey, Kamalendu,Kumar, Sanjay

, p. 258 - 263 (2013)

A new 2D polymeric Mn-acetate complex [Mn3(CH 3COO)6·2H2O]n has been synthesized in a two step reaction process and characterized by single crystal X-ray crystallography, IR and thermal analyses. Structural analysis indicates that complex 1 crystallized in the P21/n space group and also shows that syn-syn and μ-oxo bridging of acetate ligands forms antiferromagnetic trimeric metal cores which are further connected by syn-anti and anti-anti bridging of acetates, leading to the formation of a 2D coordination sheet structure. These 2D coordination sheets are further connected by supramolecular hydrogen bonding interactions, leading to the formation of a 3D supramolecular structure. During the 3D supramolecular structure formation, the complex forms both right handed and left handed helical supramolecular chains. A variable temperature magnetic study indicates that complex 1 is antiferromagnetic above 105 K, while at lower temperatures (a clear hysteresis loop.

Synthesis method of dimethylglyoxime

-

Paragraph 0033; 0034; 0053; 0054; 0080, (2017/06/02)

The invention relates to a novel method for synthesizing dimethylglyoxime. The method comprises the following steps: 1) setting the thermostatic reaction temperature to 10-70 DEG C, and adding a catalyst into a solvent ethanol-butanedione mixed liquid, wherein the ethanol is 10-20 times by mass of the butanedione; and 2) adding stronger ammonia water and oxydol into the mixed liquid in the step 1) by 1-3 times within 0.5-1 hour, and reacting for 0.5-6 hours, wherein the mole ratio of the butanedione, oxydol and ammonia water is 1:(2-3.5):(2-4), and the catalyst is a titanium silicon molecular sieve and is 1-4 times by mass of the butanedione. Compared with the prior art, the reaction steps are reduced, thereby implementing one-step synthesis of dimethylglyoxime; the solid powder catalyst can be easily separated from the reaction system, and can be recycled, thereby enhancing the dimethylglyoxime production efficiency to some extent; and the used raw materials have low toxicity and no harm, and the reaction byproduct is water and is almost not hazardous to the environment, thereby satisfying the requirements of green chemical industry.
