A process for the manufacture of sulfamoyl anthranilic acids of the general formula I ##STR1## in which Ph is phenyl substituted with 1 or 2 halogen atoms, alkyl groups or etherified hydroxy groups, and R is aralkyl, heteroaralkyl or cycloalkyl-alkyl, unsaturated in the aliphatic moiety, including oxygen or sulfur and/or substituted with halogen, alkyl or alkoxy in the aromatic moiety, by reacting carboxylic acids with at least one mol-equivalent of an amine (R--NH.sub.2) at a temperature above 120.degree. C.

蒽酸的方法,其中Ph是苯基,置换有1或2个卤素原子、烷基或醚化羟基,而R是芳基烷基、杂芳基烷基或环烷基烷基,脂肪基具有不饱和性,包括氧或
硫,和/或在芳基部分置换有卤素、烷基或烷氧基,通过将
羧酸与至少一个摩尔当量的胺(R-NH.sub.2)在120℃以上的温度下反应。
