IR AND EPR STUDIES OF THE NUCLEAR ALKYLATION OF TOLUENE AND ETHYLENE ON THE MODIFIED Mg—AND P—ZSM—5 CATALYST

摘要

The surface intermediate （C2H5+ and CH3C6H5+） and the reactive pathway of nuclear alkylation of toluene with ethylene to para—ethyl toluene over Mg salt and phosphorus acid modified ZSM—5 zeolites have been studied by 1R and EPR methods.
