ABSTRACT:
This present invention is a process for alkylating aromatic amines to form ortho-alkylated products in high selectivity relative to N-alkylated products. Aromatic amines are contacted with an olefin or an alcohol in the presence of an ion exchanged zeolite in which at least a portion of the exchangeable ion sites have been exchanged with Al cations.
