2,3-Butanedione monoxime is a chemical substance, molecular formula C4H7NO2. White to yellowish crystalline powder. The melting point is 74 degrees (76 degrees) and the boiling point is 185-186 degrees. Slightly soluble in water, soluble in ethanol, ethyl ether and chloroform. For qualitative examination of Ni2+ and spectrophotometric determination of Ni2+, Co, Pt4+ and Pd2+ color reagents, but also for the spectrophotometric determination of urea and urea. Pharmaceutical intermediates. It was obtained by reaction of methyl ethyl ketone with ethyl nitrite. Methyl ethyl ketone and hydrochloric acid are added into the reaction pot and the ethyl nitrite gas is immediately passed into the reaction pot. The reaction is maintained at 40-55 C until gas passes through. The ethanol produced by vacuum distillation was stopped and distilled at 90 degrees centigrade to obtain two ketone monoxime. The yield is 82-87%.
