    摘要： Residues from the distillation of a toluene diamine phosgenation mixture are hydrolyzed by mixing them with water and subjecting the mixture to a temperature of 200-350 ° C. The hydrolysis is performed in the presence of a sufficient amount of a base to maintain the pressure in the reactor to no more than a predetermined operating level. The product mixture is then extracted to recover TDA, which can be recycled. This provides an efficient process whereby nearly quantitative conversion of the residues to TDA can be achieved.
