Production of chloro-s-triazine triones

摘要

{PG,1 Chloro-s-triazine triones having improved crystal properties are obtained by reacting cyanuric acid, alkali metal hydroxide and chlorine in an aqueous reaction mixture in the presence of a crystal modifier selected from the group consisting of alkali metal disulfonates of alkylated diphenyloxide wherein the alkyl group contains from about 8 to about 14 carbon atoms, and alkylated diphenyloxide disulfonic acid wherein the alkyl group contains from about 8 to about 14 carbon atoms.
