Abstract of the Disclosure A process for the preparation of a 1-amino-1,3,5- triazine-2,4(1H, 3H)-dione compounds comprising the steps of reacting an N-substituted imido-dicarboxylic acid diaryl ester with an isothiosemicarbazone at a temperature of between 50° and 150°C to form a 1-alkylidene-amino-1, 3, 5-triazine-2.4(1H, 3H)- dione reacton product; and thereafter, hydrolzing the reaction product in an acid medium. The reaction product need not be separated from the reaction mixture before the hydrolysis step. Certain novel 1-amino-1,3,5-triazine-2,4(1H, 3H)-dione compounds are provided. The compounds are useful as herbicides.
