Description: dimethylglyoxime, 2,3-butandiondioksim, dihydroxy diacetyl. Dimetildioksim is a colorless crystals; mp 238-240 ° C. Dimethylglyoxime soluble in alcohol, ether and alkali solutions; nickel salts form insoluble precipitate red dimetilglioksimata nickel
Application: dimethylglyoxime is used for the qualitative and quantitative determination of palladium inikelya.
When interacting with the nickel ions dimethylglyoxime forms red complex which can be easily precipitated and determined gravimetrically.
