Abstract
Provided is a process for alkylating aromatic compounds in the presence of mixed oxides of titanium and gallium which have been found to be highly active catalysts for the alkylation of aromatics with alkyl esters, alcohols, olefins and ethers. When the alkyl acceptor is a phenol, the catalysts provide high reaction rates and high selectivity for ortho alkylated products.
