摘 要: 采用MCM-41为载体,通过化学法合成了5种负载咪唑类离子液体催化剂,考察了在环状碳酸丙烯酯合成中的催化作用,考察了溴代烷烃中碳链的长短及羟基官能团对催化剂催化性能的影响。结果表明,在115℃、2.0 MPa、4 h条件下,环状碳酸丙烯酯产率为89.9%,选择性为99.5%。 Five ionic liquids (ILs) supported on MCM-41 were prepared and their performances for the synthesis of propylene carbonate from CO2 and propylene oxide were investigated. The activity of catalyst is related with the length of alkyl and hydroxyl functional group. The yield and the selectivity of PC is 89.5% and 99.5% respectively at 115 ℃ and 2.0 MPa for 4 h.
