【摘要】 聚乙二醇相转移催化羧酸酯的合成谢筱娟，杨高升，杨富国，宋雪清（安徽师范大学化学系芜湖２４１０００）关键词聚乙二醇，相转移催化，酰化反应，羧酸酯通常羧酸酯的制备是利用醇与羧酸、酰氯或酸酐反应，但这个方法对有立体位阻的醇不太适宜［１］，为此，为寻找好的方...更多还原

【Abstract】 Acylation of alcohol using polyethylene glycol phase-transfer catalyst has been studied. It hasbeen found that eight esters of carboxylic acids can be obtained in good yields. The reaction of primaryor secondary alcohols with acylations agent is carried out by liquid-liquid PTC and tertiary aicoholswith acetyl chloride is carried out by solid-llquid PTC.更多还原
