摘　　要：以NaHSO4·H2O为催化剂,通过正丁酸与2 戊醇反应合成了丁酸2 戊酯。讨论了影响酯化率的主要因素,实验结果表明,当催化剂用量为0.6g,醇酸摩尔比为1.4∶1,反应温度为125℃,反应时间为3h时,平行实验酯化率的平均值可达97.9%。该工艺具有催化剂价廉易得,催化效果好,用量少,易分离,步骤少,操作简单,三废少,收率高等优点。2-myl butyrate is synthesized from n-butyric acid and 2-amylalcohol in the presence of sodium hydrogen sulphate.The primary factors which influence the esterification efficiency of n-butyric acid are discussed.The results show that the average esterification efficiency of parallel experiment can reach 97.9% with quantity of catalyst of 0.6g,the molar ratio of alcohol to acid of 1.4∶1,reaction temperature of 125℃,reaction time of 3h.The process has advantages of cheap and easily available catalyst,good catalytic results,less amount,easy separation,simple operation,less three wastes and high yield etc.
