Abstract: A process for producing a mono-alkylated benzene comprises contacting benzene with di-alkylated benzene(s) and/or tri-alkylated benzene(s) in the presence of a transalkylation catalyst composition under transalkylation conditions to convert at least part of the di-alkylated benzene(s) and tri-alkylated benzene(s) to mono-alkylated benzene. The transalkylation catalyst composition comprises a treated zeolitic material having increased mesoporous surface area compared to the precursor catalyst composition from which it is made.
