【Abstract】 Long 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.更多还原
