Abstract of the Invention Dichloroacetylamides selected from the group consisting of: a) N,N-diallyldichloroacetamide, and b) N-dichloroacetyl oxazolidines having the formula Image in which R is hydrogen or C1-C3 alkyl are produced in a continuous circulating process by reaction of dichloroacetyl chloride with respectively N,N- diallylamine or an oxazolidine having the formula Image in the presence of an aqueous solution of sodium hydroxide. The conduct of this process in a con- tinuous circulating fashion produces the desired amide in greater yield than by the heretofore practiced batch processes.
