摘　　要：本文研究了1-烯丙基-3-乙烯基咪唑氯盐(AVIM)Cl功能化离子液体的合成工艺。采用两步合成法,由N-烯丙基咪唑与1,2-二氯乙烷,三乙胺通过两步季铵化反应制得,通过对合成条件进行实验分析。结果表明:N-烯丙基咪唑和1,2-二氯乙烷按摩尔比1︰1.2混合,60℃下反应30h;1-烯丙基-3-(2-氯代乙基)氯化咪唑嗡与胺类物质按摩尔比1∶1.5混合,50℃下反应20h为最佳合成条件。采用IR、~1H NMR、^(13)CNMR对产物进行表征,结果表明所合成的产物确为目标离子液体。In this work, the synthesis of l-allyl-3-vinylimidazolium chloride （AVIM）Cl functionalized ionic liquids was studied. Using two-step synthesis, the 1-allyl-3-vinylimidazolium chloride （A VIM）Cl functionalized ionic liquid was made of by N-allyl imidazole and 1,2-dichloroethane, triethylamine by two-step quaternization reaction in the system. The results showed that N-allyl imidazole and 1,2-dichloroethane were mixed at a molar ratio of 1： 1.2, reacted at 60℃ for 30h; 1-allyl-3- （2-chloroethyl） Imidazole and Amine were mixed at a molar ratio of l ： 1.5 and reacted at 50℃ for 20h for the optimum synthesis conditions. The products were characterized by IR , 1H NMR and 13C NMR. The results showed that the synthesized product was the target ionic liquid.
