| Abstract: | Acidic ionic liquids were synthes!zed using AlC;3, FeCl3 and 1-alkyl-3-methy limidazolium bromide （ [ Rmim] Br） for 1-butene polymerization, The influence of reaction temperature, catalyst dosage,reactiOn time, reaction pressure and the molar ratio of anions/cations in ionic liquids on the selectivity to oligomer were investigated. The results showed that the acidic ionic liquid prepared with [ C4mim] Br and FeCl3 exhibited better selectivity. Among the products,the selectivity to C8 olefins of 0. 23% ,Cl2 olefius of40.45%, C16 olefins of 43.75% ,and C20 olefins of 15.57% were attained under the reaction condition as follows： room temperature,catalyst dosage 2：0 g, reaction time 2 h, reaction pressure O. 10 MPa, and anions/ cations molar ratio 1： 1. |
