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,n-十二烷基苄醇的产率达到93.6%。

Abstract:
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 dodecyldimethylbenzylammonium 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%.
Key words:  dodecylbenzyl chloride  hydrolysis  hydrothermal  phase transfer catalysis
