摘要/Abstract

摘要：

离子液体（C₂H₅）₃NHCl-xFeCl₃（FeCl₃摩尔分率x≥0.55）对异丁烯齐聚反应具有良好的催化性能。在反应温度40℃，反应时间30 min，酸烃比为1.2∶1的条件下，异丁烯齐聚转化率达到85%，液相产物中二聚物和三聚物的含量之和达到80%以上。在离子液体中引入适量CuCl可以提高异丁烯的转化率。当CuCl/[（C₂H₅）₃NH]Cl-0.6FeCl₃的摩尔比为0.25时，异丁烯的转化率达到98%，液相产物中二聚物和三聚物的含量之和高达90.20%。

Abstract:

The oligomerization of butene is one of important process in chemical and oil refining industries. Its products are important chemical raw materials. Liquid isobutene oligomerization is investigated in a batch autoclave. The ionic liquid (C₂H₅)₃NHCl-FeCl₃ (mole fraction of FeCl₃ is more than or equal to 0.55) shows good catalytic performance for the oligomerization of isobutene. Under good operating conditions, conversion of isobutene is above 85%, and the total mass content of dimers and trimers in oligomers is above 80%. Addition of CuCl in the ionic liquid can increase both isobutene conversion and the selectivity of dimers and trimers. When the mole ratio of CuCl to[(C₂H₅)₃NH] Cl-0.6FeCl₃ is 0.25, the mass content of dimers and trimers in oligomers reach up to 90.20% and conversion of isobutene is 98%.

Key words: oligomerization, ionic liquid, iron(Ⅲ) chloride, isobutene, copper (Ⅰ) chloride
