Dimethylglyoxime Dmg Is An Organic Compound Used To Test

/ Comments off

Dimethylglyoxime, DMG, is an organic compound used to test for aqueous nickel(II) ions. A solution prepared by dissolving 65.0 g of DMG in 375 g of ethanol boils at 80.3°C. What is the molar mass of DMG? Kb = 1.22°C/m, boiling point of pure ethanol = 78.5°C. Dimethylglyoxime, DMG, is an organic compound used to test for aqueous nickel(II) ions.

Nickel(II) forms a precipitate with the organic compound dimethylglyoxime, C4H6(NOH)2. The formation of the red chelate occurs quantitatively in a solution in which the pH is buffered in the range of 5 to 9. The chelation reaction that occurs is illustrated below. Although the loss of one proton occurs from one oxime group (NOH) on each of the two. Nickel Dimethylglyoxime (Ni(dmg) 2) is one of numerous organometallic compounds manufactured by American Elements under the trade name AE Organometallics™. Organometallics are useful reagents, catalysts, and precursor materials with applications in thin film deposition, industrial chemistry, pharmaceuticals, LED manufacturing, and others.

Colorless crystals; melting point, 238°-240°C. It is soluble in alcohol, ether, and solutions of alkalies. With nickel salts it yields a red insoluble precipitate of nickel dimethylglyoximate, (C4H7O2N)2Ni, which is a chelate compound. Because of this, dimethylglyoxime is used for the qualitative and quantitative determination of nickel. In 1905, L. A. Chugaev suggested the use of dimethylglyoxime as a specific reagent for nickel. Dimethylglyoxime is made by treating diacetyl with hydroxylamine.

Summary

A general technique for the detection of nickel with dimethylglyoxime in the presence of considerable amount of interferent cations, even in complex mixtures, has been worked out. The influence of numerous anions in the reaction has been established. The method has been successfully applied to pure salts, minerals and metallic samples.

Zusammenfassung

Ein allgemein anwendbares Verfahren zum Nachweis von Nickel mit Dimethylglyoxim in Gegenwart erheblicher Mengen störender Kationen, auch in Vielfachgemischen, wurde ausgearbeitet. Die Beeinflußbarkeit der Reaktion durch mehrere Anionen wurde festgestellt. Die Methode wurde mit Erfolg auf die Analyse reiner Salze, Minerale und metallischer Proben angewendet.
