IN THE UNITED STATES PATENT OFFICE PROCESS FOR THE PRODUCTION OF N,N-DIALLYLDICHLOROACETAMIDE Abstract of the Invention A novel process is described herein for the efficient production of N,N-diallyldichloroacetamide by reaction of diallylamine and dichloroacetyl chloride. The process comprises admixing an excess of diallylamine with sufficient strong aqueous sodium hydroxide such that at all times during the reaction, the pH of the reaction mixture remains above a pH of 10, then slowly adding di- chloroacetyl chloride to said mixture under violent agitation, while maintaining the reaction temperature from about -10 to about 100°C to effect production of N,N-diallyldichloroacetamide in yields in excess of 80%, while eliminating the production of amine salt by-products.
