摘　　要：在高压釜式反应器中,以甲醇和异戊烯为原料,增强型离子交换树脂Amberlyst为催化剂,制备了高辛烷值醚化汽油组分TAME。改变反应温度、催化剂用量等单一实验变量,探索得到了最佳工艺条件:反应温度70℃,催化剂用量为20%,醇/烯比为2。在最优条件下,该催化反应只需进行4.5h,TAME的摩尔产率就达到70%。TAME was prepared in autoclave reactor applied methanol and isopentene as raw materials and enhanced ion exchange resin as catalyst.By changing the reaction temperature and catalyst dosage,the optimum technological conditions were obtained as followed:temperature 70℃,catalyst dosage 20%,ratio of alcohol/olefin was 2.Under the optimum conditions,the catalytic reaction only took 4.5h,and the molar yield of TAME reached 70%.
