氟化N-(3-长链烷氧-2-羟)丙基-N,N,N-三甲基铵的合成及其氟交换相转移催化性能研究

Synthesis of N-(3-Long Chain Alkyloxyl-2-hydroxy) Propyl-N,N,N-trialkylammoium Fluorides and It's Properties

以脂肪醇和环氧氯丙烷为原料合成长链烷基缩水甘油醚 ,然后和三甲胺氢氟酸盐反应得到氟化N - (3-长链烷氧 - 2 -羟 )丙基 -N ,N ,N -三甲基铵 ,其结构通过红外光谱、核磁共振氢谱及元素分析结果得以证实。同时还研究了其对 2 ,4 -二硝基氯苯氟交换生成 2 ,4

N-(3-alkyloxyl-2-hydroxyl)propyl-N,N,N-trimethylammoium fluorides were synthesized by reaction of trimethylamine hydrigen fluoride and long chain alkyl glycidyl ether which were prepared from fatty alcohols and epichlorohydrin.Their structures were confirmed by IR.,HNMR and elemental analysis. Their phase transfer catalysis ability for the fluorine exchange reaction were also researched in this paper.
