Significance of the hydrolysis of some aliphatic and aromatic dicarboxylic acid chlorides in interphase polycondensation

Abstract

1. A study was made of the hydrolysis of adipoyl, sebacoyl, isophthaloyl, and terephthaloyl chlorides under the conditions of interphase polycondensation. 2. The amount of acid chloride hydrolyzed increases with increase in reaction time, but the rate of hydrolysis gradually falls. 3. The rate of the hydrolysis of the dicarboxylic acid chlorides investigated increases with rise in reaction temperature and alkali concentration. 4. The tendency for the investigated dicarboxylic acid chloride to hydrolyze diminishes in the following order: adipoyl chloride, sebacoyl chloride, isophthaloyl chloride, terephthaloyl chloride. © 1963 Consultants Bureau.
