Abstract:

Et3NH]Cl-2AlCl3 ionic liquid was used to catalyze the alkylation reaction of benzene and 2-chloropropane to prepare cumene.The effects of reaction conditions were investigated.The results showed that under the optimal conditions of molar ratio of benzene to 2-chloropropane were 3.3,amount of catalyst 10% of benzene mass,and reaction temperature 55℃,the conversion rate of benzene could reach 29.38% and the selectivity of cumene was 90.60%.The Et3NH]Cl-2AlCl3 ionic liquid could be recycled for 5 times.
