摘要 用KF/Al2O4催化1-甲酰氧基-2-甲基-4-乙酰氧基-2-丁烯进行酯交换反应制备1-羟基-2-甲基-4-乙酰氧基-2-丁烯,提高了反应选择性,并因采用反应精馏方式将反应时间缩短到5 h,收率由77%提高到95%,后处理方便. 1-Hydroxy-2-methyl-4- acetyloxy-2- butene was prepared by ester exchange reaction catalyzed by KF/Al2O3 from 1-formyloxy-2-methyl-4- acetyloxy-2-butene,the reaction selectivity is enhanced. Moreover,reaction time is shortcut,yield is raised and the process is simplified by the adoption of reaction-distillation method,which has a great industrial value. This new method demonstrates significance to the synthesis of similar compound via ester exchange reaction.
