  • Process for the production of 1,3-dichloroacetone oxime and its acetate derivative
    Patent number: 4128580
    Abstract: 1,3-dichloroacetone oxime is prepared from 1,3-dichloropropanone by reaction with a hydroxylamine salt in a strongly acidic medium in the presence of a base selected from the group consisting of tertiary amines, lower alkyl amides, alkali metal bicarbonates, alkali metal carbonates and alkaline earth metal carbonates. 1,3-dichloroacetone oxime acetate is advantageously prepared by reaction of the oxime with acetic anhydride. The acetate is obtained in high purity.
