Description of Butane dioxime

Dimethylglyoxime is a chemical compound described by the formula CH3C(NOH)C(NOH)CH3. Its abbreviation is dmgH2 for neutral form, and dmgH for anionic form, where H stands for hydrogen. This colourless solid is the dioxime derivative of the diketone butane-2,3-dione (also known as diacetyl). DmgH2 is used in the analysis of palladium or nickel. Its coordination complexes are of theoretical interest as models for enzymes and as catalysts. Many related ligands can be prepared from other diketones, e.g. benzil.

What is Butane dioxime?

• With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives.
•  One such product is Butane dioxime which has developed particularly rapidly in recent years. Do you know about Butane dioxime?
• The official answer: White crystals. Melting point 238-240°C. Soluble in alcohol, ether, acetone and pyridine. Only 0.5g per litre of water can be dissolved, and the solubility in chloroform, toluene and xylene is also very small. Derived from the reaction of butanedione monoxime with sodium hydroxylamine-sulphonate. Add butanedione monoxime to sodium hydroxylamine-sulphonate solution, heat to 70°C and maintain warmth for several hours to precipitate butanedione oxime crystals, filter immediately after cooling and wash with ice water until no longer containing with sulfate, that is. Sodium hydroxylamine-sulphonate can be prepared as follows: mix sodium nitrite Chemicalbook acid with crushed ice, stir while adding a suspension of sodium bisulphite with water, then add glacial acetic acid from below the liquid surface under stirring, followed by concentrated hydrochloric acid and crushed ice, so that the reaction solution has been kept below 0 ℃, with Congo red test paper test is acidic reaction, filtering to remove insoluble precipitate is obtained hydroxylamine-sulphonate solution. sodium sulphonate solution.

What’s the application of Butane dioxime?

Use as an analytical reagent and as a redox indicator and as a reagent for chromatographic analysis Uses Determination and determination of nickel; separation of nickel from cobalt and other metals, palladium from tin, gold, rhenium, iridium, etc.; photometric determination of cyanide, nickel, palladium, cobalt, iron(II), rhenium(VII)
