Abstract
1501688 Diamides of aromatic and cycloaliphatic dicarboxylic acids AKZO NV 25 July 1975 [3 Aug 1974] 31173/75 Heading C2C Diamides of aromatic and cycloaliphatic dicarboxylic acids are prepared by ammonolysis of an oligoester or polyester of the corresponding dicarboxylic acid with a polyhydric alcohol in the presence of from 100 to 1000% by weight based on the ester of a polyhydric alcohol at 30 to 200 C. under an ammonia partial pressure of 0À1 to 50 atmospheres. Reference has been directed by the Comptroller to Specification 1,399,405.
