Dimethylglyoxime Chemical Properties,Uses,Production

Chemical Properties

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).

Chemical Properties

Dimethylglyoxime is  white crystalline powder

Uses

Dimethylglyoxime is  used as nickel-specific complexing reagent; determination of palladium.

Uses

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.

Uses

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.

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.
