| Abstract: | The synthesis of dibutyl phthalate（DBP） was made from the reaction between n-butanol and phthalic with molybdovanado-phosphoric heteropoly acids as catalyst. The influential factors of reaction were investigated and the optimized conditions were drawn through orthogonal experiment：molar ratio of n-butyl alcohol to phthalic anhydride was 1 ： 2.4 ; temperature is 120℃ ; Catalyst＇ s weight was 3 % of phthalic anhydride＇s weight,and reaction time was 2 h. The yield of DBP is about 94.20%. |
