Abstract
Use of cupric sulphfate as catalyst on the esterification of dibutyl sebacate was studied The optimized conditions are as following:the weight of catalyst is 3 0g/0 05mol sebacic acid,the mole ratio of alchol to acid is 4,the reaction tim is 3 0h and 12ml benzene as water carrier The esterification yield for sebacic acid is about 97 23% Experimental results showed that cupric sulfate is a highly active catalyst for this reaction Less catalyst is required with little waste dischargement It is an inexpensive and very practical method
