ABSTRACT:
Monoalkylated benzene such as ethylbenzene and cumene or monoalkylated substituted benzene are produced by alkylation in the presence of an acidic mordenite zeolite catalyst having a silica/alumina molar ratio of at least 40:1, preferably 160:1. In a subsequent, optional process, the polyalkylated benzene or polyalkylated substituted benzene produced in the alkylation is transalkylated in the presence of an acidic mordenite zeolite catalyst.
