Alkylated aromatic compounds, either alone or in a mixture with an alkylating agent, are disproportionated, alkylated or transalkylated in the presence of a ZSM-22 zeolite. The products of the reactions contain the amounts of the para-isomer which are in excess of the equilibrium amounts of such isomer. Alternatively, 1,2-disubstituted, 1,3-disubstituted and/or 1,4-disubstituted aromatic compounds are contacted with the ZSM-22 zeolite under cracking conditions to selectively crack the 1,4-disubstituted isomer.
