摘要
以钨锗杂多酸Ｈ４ＧｅＷ１２Ｏ４０为催化剂，研究了对硝基苯甲酸与乙醇的液相酯化反应。考察了催化剂用量、反应时间、醇酸比等对合成产物的影响，给出了适宜的酯化工艺条件，此时对硝基苯甲酸乙酯的产率达到７８８％。
Tungstogermanic heteropoly acid H_4GeW_12O_40 was used as the catalyst for the esterification of p-nitrobenzoatic acid with ethyl alcohol in liquid phase.Effects of the amount of the catalyst used,the reaction time and the ratio of reactants were investigated.The suitable condition synthesizing the ester was obtained.Under the condition,the yield of ethyl p-nitrobenzoate could reach 78.8%.
