Abstract
The technological conditions of catalytic synthesis of dibutyl phthalate by tungstosilicic acid was studied in this paper.The experimental results showed that the optimum synthetic conditions were phthalic anhydride/n butylalcohol molar ratio 1∶3,catalyst and benzene amount of total quantity were 2 6% and 42 8%,respectively,the reaction time was 2 5 h,and the yield of dibutyl phthalate was amout to 99 22%.
