含羟基连接基的咪唑双子表面活性剂的合成研究

Synthesis of Gemini imidazolium surfactants with hydroxyl spacers

以咪唑、溴代烷(溴代辛烷、溴代癸烷、溴代十二烷、溴代十四烷、溴代十六烷)为原料,合成了一系列N-烷基咪唑.再以N-烷基咪唑、1,3-二氯-2-丙醇为原料,合成了5个含羟基连接基的咪唑双子表面活性剂.用单因素法考察了投料比、反应温度、反应时间对目标产物收率的影响,利用1H-NMR、IR和元素分析对目标产物的结构进行表征.

A series of N-alkyl imidazoles were synthesized from imidazole and bromoalkyl （bromooctane, bromodecane, bromododecane, bromotetradecane, bromohexadecyl）. Five Gemini imidazolium surfactants with hydroxyl spacers were synthesized using N-alkyl imidazole and 1,3-dichloropropan-2-ol as materials. The influences of molar ratio, reaction temperature and reaction time on the yield of target product were investigated through single factor method. The products were identified by 1H-NMR, IR and elemental analysis.
