摘要
以纳米复合杂多酸为催化剂,通过马来酸和正辛醇反应合成马来酸二辛酯,探索了各种因素对酯化率的影响。实验结果表明,纳米复合杂多酸是合成马来酸二辛酯的良好催化剂,在物料比n(马来酸):n(正辛醇)=1:3、催化剂用量为反应物总质量的3%(马来酸为0.05mol)、苯10mL、反应1h的条件下,酯化率可达98.4%。
Dioctyl maleate was synthesized from maleic acid and n-octanol using nano-H3PW12O40/SiO2 as catalyst, and the factors influencing on the yield of dioctyl maleate were investigated. The result showed that nanometer complex heteropoly was a good catalyst for synthesizing dioctyl maleate. The esterification ratio was up to 98.4% when molar ratio of maleic acid and n-octanol was 1 ： 3, the amount of catalyst in reactants was 3% （base on 0.05 mol maleic acid）, benzene was 10 mL, and reaction time was 60 min.
