摘　　要：分别以氯化1-丁基-3-甲基咪唑([Bmim]Cl)、盐酸三乙胺([Et3NH]Cl)为阳离子,氯化锌和氯化铁为阴离子,合成酸性离子液体催化剂,用于1-己烯齐聚反应研究。结果表明,以[Bmim]Cl为阳离子、ZnCl2为阴离子,催化剂阴阳离子物质的量的比为1.5∶1,并加0.09 mL硫酸改性处理时,即形成[Bmim]Cl-ZnCl2-H2SO4酸性离子液体催化剂体系,此催化剂体系活性和选择性较好,且可循环使用。这为进一步工业化开发酸性离子液体催化合成聚α-烯烃合成油提供了基础数据。Acidic ionic liquid was synthesized with Cl or Cl as cations,ZnCl2 or FeCl3 as anions.Four types of acidic ionic liquid including Cl-ZnCl2,Cl-ZnCl2,Cl-FeCl3 and Cl-FeCl3 were used to catalyze the oligomerization of α-olefin.This catalyst was combined with Cl as the cation and ZnCl2 as anion,molar ratio of anions to cations was 1.5 ∶ 1,and three drops of sulfuric acid were added for modifying acidity.The ionic liquid of Cl-ZnCl2-H2SO4 could effectively catalyze oligomerization and had higher selectivity,additionly,this catalyst could be recycled.It provided a fundamental data for studying the poly-α-olefins synthetic lubricant catalyzed by acidic ionic liquid in industry.
