A process for producing a monoalkylated benzene comprises contacting benzene with a mixture comprising dialkylated and trialkylated benzenes in the presence of a transalkylation catalyst composition under transalkylation conditions effective to convert at least part of the dialkylated and trialkylated benzene to monoalkylated benzene, wherein the catalyst composition comprises a metallosilicate zeolite comprising openings defined by 14-membered rings of tetrahedrally coordinated atoms and the transalkylation conditions include a temperature in the range of 160&#xb0; C. to 220&#xb0; C.

Production of alkylaromatic compounds

A process for producing a monoalkylated benzene comprises the step of contacting benzene with a mixture comprising dialkylated and trialkylated benzenes in the presence of a transalkylation catalyst composition under transalkylation conditions effective to convert at least part of the dialkylated and trialkylated benzene to monoalkylated benzene, wherein the transalkylation catalyst, composition comprises zeolite beta having an external surface in excess of 350 m2/g as determined by the t-plot method for nitrogen physisorption.
