摘　　要：采用超声、微波、水热、相转移催化等多种方法对n-十二烷基苄氯的碱性水解反应进行初步尝试,其中相转移催化与水热条件偶合水解获得了成功。优化的工艺条件为:十二烷基二甲基苄基氯化铵为相转移催化剂,在130℃下碱性水热反应16 h,此条件下n-十二烷基苄醇的产率达到93.6%。Hydrolysis of n - dodecylbenzyl chloride was preliminarily tested separately by means of ultrasonic wave, microwave, hydrothermal and phase transfer catalysis, and finally the hydrothermal -assisted phase transfer catalysis succeeded. Based upon the test results, the conclusion is to use dodecyldimethylbenzyl- ammonium chloride as the phase transfer catalyst and the reaction is conducted under alkaline condition with hydrothermal assistance at 130℃ for 16 h. The yield achieves 93.6%.
