| Abstract: | Property, application and synthesis of dibutyl oxalate by using composite catalyst were introduced. The optimal condition were：the ammont of catalyst I was equal to 1.5% of the total mass of total feed stock, n （n -butanol） ： n （oxalic acid） =3.5 ： 1 ,refluxing me 3 h,the yield and purity of dibutyl oxalate were96% and 99.6%. The ammont of catalyst 11 was equal to 3.9% of total mass of total feed stock, n（ n -butanol） ： n（oxalic acid） = 2.38 ： 1 ,under toluene refluxing time 1.5 h, the yield and purity of dibutl oxalate were 99.4% and 99.7%. The reaction was easy to operate, and catalyst had high catalytic activity, good repeatability, high yields of product and non pollution. |
