    摘要: A process for the manufacture of 3-(3,5-dichlorophenyl)-hydantoin comprises cyclizing 3-(3,5-dichloro-phenyl)-ureidoacetic acid in the presence of a catalytic amount relative to the ureidoacetic acid of an acid dehydrating agent and in the presence of an organic solvent which forms an azeotrope with water; the water formed during the reaction is eliminated by azeotropic distillation.
