Abstract
A process for producing m-xylene, which comprises isomerizing a hydrocarbon material containing o-xylene as a main ingredient in the presence of a catalyst composition comprising zeolite ZSM-4 and/or zeolite omega under such conditions that m-xylene is selectively formed, and recovering m-xylene by distillation from the resulting isomerization mixture containing o-xylene and m-xylene as main ingredients.

A process for producing m-xylene, which comprises isomerizing a hydrocarbon material containing o-xylene as a main ingredient in the presence of a catalyst composition selected from the group consisting of zeolite ZSM-4, zeolite omega and mixtures thereof at a temperature of about 100.degree. to 200.degree. C. to selectively form m-xylene, and recovering m-xylene by distillation from the resulting isomerization mixture containing o-xylene and m-xylene as main ingredients.
