FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to an improved method for synthesis of dichloroglyoxime. Method involves dosing concentrated hydrochloric acid and perhydrol simultaneously and proportionally at stirring to glyoxime suspension in the mole ratio glyoxime : hydrochloric acid : hydrogen peroxide = (1.0-2.0):(2.2-2.4):2.4, respectively, in the weight ratio of the total water amount and calcium chloride = (1.2-2.8):1.0 and temperature 15-250C. Method provides preparing the end product with the yield 81-93%.
EFFECT: improved method of synthesis.
