Yang, Shuqing published the artcileOligomerization of isobutene catalyzed by AlCl3 ionic liquids, HPLC of Formula: 23616-79-7, the publication is Shiyou Lianzhi Yu Huagong (2012), 43(5), 14-18, database is CAplus.
AlCl3 ionic liquids having various cations and anions were synthesized. Tests for oligomerization of isobutene catalyzed by various AlCl3 ionic liquids were conducted in an autoclave, and the effect of reaction temperature, reaction time and stirring speed was studied. Exptl. results indicated that these AlCl3 ionic liquids exhibited good catalytic performance in isobutene oligomerization with conversion of isobutene over 95%. For ionic liquids synthesized by AlCl3 and (C2H5)3NHCl, when the mole ratio of AlCl3 to(C2H5)3NHCl was below 1, the AlCl3 ionic liquid was inactive to isobutene oligomerization. When the mole ratio of AlCl3 to(C2H5)3NHCl was 1, the ionic liquid exhibited certain catalytic activity and its selectivity to dimers and trimers was good. When the mole ratio of AlCl3 to (C2H5)3NHCl was above 1, these ionic liquids could effectively catalyze oligomerization reactions, the conversion of isobutene reached more than 95%, yet the selectivity to dimers and trimers declined and the product distributions were continuous with certain amount of cracking byproducts. The optimal reaction conditions were as follows: a reaction temperature of 80°C, a reaction time of 30 min and stirring speed of 1300 r/min.
