Abstract
A process for the alkylation or transalkylation of an aromatic hydrocarbon which comprises contacting the aromatic hydrocarbon with a C.sub.2 to C.sub.4 olefin alkylating agent or a polyalkyl aromatic hydrocarbon transalkylating agent, under at least partial liquid phase conditions, and in the presence of a catalyst comprising zeolite beta.
Claims16
A process for the alkylation of an aromatic hydrocarbon which comprises contacting a stoichiometric excess of the aromatic hydrocarbon with a C.sub.2 to C.sub.4 olefin under at least partial liquid phase conditions and in the presence of a catalyst comprising zeolite beta wherein there are at least two catalyst beds or reactors in series and at least a portion of the aromatic hydrocarbon is added between the catalyst beds or reactors.
