十二烷基磺酸锌催化合成乙酸正丁酯
Catalytic Synthesis of n-Butyl Acetate by Zinc di(dodecanesulfonate )
【摘要】 研究了乙酸和正丁醇在十二烷基磺酸锌催化下的反应 ,考察了反应时间、催化剂用量、酸醇比等因素对产品乙酸正丁酯收率的影响。当催化剂用量为 0 .0 0 4mol,正丁醇和乙酸的摩尔比为 0 .6 ,回流搅拌反应 2 0min时 ,产品乙酸正丁酯的收率可达 86 .3%。
【Abstract】 This manuscript reported the esterification of acetic acid with n-butanol catalyzed by Zinc didodecanesulfonate .The effect of different factors, such as reaction time, catalyst dosage ,the ratio of acetic acid to n-butanol, on the yield of n-butyl acetate were carefully studied. When the catalyst dosage was 0.004 mol ,the ratio of n-butanol to acetic acid was 0.6,the reaction time was 20 min under stirring and refluxing, the yield of n-butyl acetate reached 86.3 %.
