摘要
以磷钨杂多酸为催化剂，通过乙酸和正己醇的酯化反应合成了乙酸正己酯，并对影响酯化率的因素进行了研究．结果表明：反应的最佳条件为：乙酸为0．1mol时，醇酸物质的量比为1．4，催化剂用量为0．3g，带水剂为15mL，在温度为110～130℃下，反应30min，酯化率可达99．6％以上，
n-hexyl acetate was synthesized from acetic acid and hexyl alcohol with phosphotungstic acid as catalyst. The effect of factors on esterification ratio was studied. The result shows that the best reaction condition was： based on 0.1 mol acetic acid, molar ratio of n-hexyl alcohol to acetic acid was 1.4, mass of catalyst was 0.3 g, the taking water reagent was 15 mL,reaction temperature was between 110 and 130 ,reaction time was 30 min. The yield of the product could reach 99.6%.
