Method of ethylation of the monoalcylbenzene |
| abstract |
A catalytic process is provided for the ethylation of a mono alkyl benzene wherein the alkyl group contains 1 or 2 carbon atoms, i.e. toluene or ethylbenzene to yield a mixture of ethyl toluene or diethylbenzene isomers with minimal undesired by-product formation which comprises contacting said mono alkyl benzene under conversion conditions, with an ethylating agent in the presence of a catalyst comprising a crystalline aluminosilicate zeolite characterized by a constraint index, as hereinafter defined, within the approximate range of 1 to 12 and a silica to alumina ratio greater than about 500. |
