Preparation of Ethylbenzene by Alkylation of Dilute Ethylene with Benzene |
| |
| Abstract: | Ethylbenzene was prepared by alkylation of dilute ethylene(3%)with benzene using a modified HZSM-5 catalyst. Under the experimental conditions presented in this paper the conversion of ethylene was 90—95%, that of benzene was 10—20%, and the selectivity of ethylbenzene was higher than 95%. The regeneration period of the catalyst was 10—12 days. |
