摘 要:研究了一种合成三(乙烯醇)单-11-十一烷基硫醇的新方法,即以三乙二醇和1,11-二溴十一烷为底物,经过去质子化、取代、水解3步反应得到目标化合物三(乙烯醇)单-11-十一烷基硫醇。目标产物的总收率为16.5%,其结构经1H NMR确证。考察了氢化钠用量和水解反应催化剂对产物收率的影响。结果表明,当n(三乙二醇)∶n(氢化钠)=1.00∶1.00时,水解反应催化剂选用浓氨水时,3步反应的收率较高。方法副产物少,污染小,操作简单,适合小批量生产。

Abstract:A novel method for synthesizing triethylene glycol mono-11-mercaptoundecyl ether was studied.Triethylene glycol mono-11-mercaptoundecyl etherwas synthesized through a three-step reaction process includingdeprotonation, substitution and hydrolysis using triethylene glycol and 1,11-dibromoundecane as the starting materials with an overall yield of 16.5%, and its structure was characterized by 1H NMR.The influence ofthe amount of sodium hydride and the choice of hydrolysis reaction catalyst on the product yield was investigated. The results showed that the yield of the three-step reaction was highest under the conditions includingratio of n(triethylene glycol) to n(sodium hydride) at 1.00∶1.00 and concentrated ammonia as the hydrolysis reaction catalyst.This method has less by-products, simple operation, low pollution, and is suitable for small-batch production.
Key words:self-assembled monolayer film; substitution reaction; triethylene glycol mono-11-mercaptoundecyl ether
