    摘要: Lower alkyl 2-chloro-2-hydroxyiminoacetates are produced by (A) reacting chloral with a lower alkanol and a hydroxylamine salt in the presence of a Lewis acid or a metal oxide which is convertible into said Lewis acid during the course of the reaction to give a lower alkyl 2-hydroxyiminoacetate and then chlorinating the resulting product or (B) reacting chloral oxime with a lower alkanol in the presence of a base to give a lower alkyl 2-hydroxyiminoacetate and finally chlorinating the thus formed product.
