SELECTIVE ALKYLATION METHOD OF XYLENE BY ETHYLENE |
摘要 |
A process for the production of 3,4-dimethyl-1-ethyl benzene by alkylation of xylene with ethylene is carried out at a temperature of 250-600 DEG C and a pressure of 10<4/2>-10<7>N/m<2> in the presence of a crystalline zeolite catalyst having a silica to aluminia ratio of at least 12 and a constraint index of 2 to 12. The zeolite can be modified prior to use by steaming or coke deposition. |
