摘 要:以溴代烷和乙二醇或一缩二乙二醇为原料合成长链烷基(双)氧乙烯醇(收率为75% ),然后在相转移催化条件下和环氧氯丙烷反应得到长链烷基(双)氧乙烯缩水甘油醚(收率为90% ),后者和三甲胺盐酸盐反应得到氯化N[3长链烷氧(双)乙烯氧2羟]丙基N,N,N三甲基铵(收率为91% ),其结构通过红外光谱、核磁共振氢谱和元素分析结果得以证实,测定了产物的γcm 及cmLong chain alkyl(di)oxyethylene alcohols were obtained (yield 75%)by be reaction of alkyl bromides and glycol or diethylene glycol.The alcohols reacted with epichlorohydrin at the condition of phase transfer catalyst to give long chain alkyl(di) oxyethyllene glycidyl ethers(yield 90%).The ethers reacted with trimethylamine hydrin chloride and N [3 long chain alkyloxy(di)ethyleneoxy 2 hydroxy]propyl N,N,N trimethylammonium chlorides were prepared (yield 91%).Their structures were confirmed by IR,H 1NMR and elemental analysis.Their surface tension and critical micelle concentration were also determined.
