中文摘要：
制备了Hν6Pν2Wν1806213Hν20 催化剂，并通过FT-IR、UV．Vis、TG-DSC对催化剂进行表征．以乙酸正丁酯合成反应为探针考察催化剂的催化性能．研究了磷钨酸用量、醇酸比、反应时间和反应温度对反应的影响，并提出可能的催化机理．结果表明，最优的反应条件是：催化剂用量为0．72％（按反应体系总质量计算），醇酸比为2．0：1．0，反应时间为2．0h，反应温度为125℃，在此条件下酯化率可达96．83％．
英文摘要：
Abstract： Phosphotungstics acid with Dawson structure and characted by FT-IR, UV-Vis and TG-DSC. The catalytic performance in synthesis of n-Butyl acetate with acetic acid and n-butanol was investigated and the mechanism was discussed. The optimized condition were as follows： the mass ratio of the catalyst to total reactant was 0.72%, the molar ratio of n-butyl alcohol to acetic acid was 2.0 ： 1.0, the reaction time was 2.0 h, the reaction temperature was 125 °C. Yield of n-Butyl acetat could reach 96.83% under the optimum conditions.
