ABSTRACT:
Aromatic amines are alkylated by reaction with an alcohol in the presence of a Group VII-B metal oxide alkylation catalyst, preferably a major proportion of a Group VII-B metal oxide such as MnO.sub.2 in combination with a minor proportion of a Group VIII metal oxide such as Fe.sub.2 O.sub.3, so that alkylation of the aromatic amine occurs. Under most reaction conditions a considerable portion of the alcohol alkylating agent such as ethanol not consumed in the alkylation reaction passes through the reaction zone undecomposed and thus can be readily recovered for recycle or other use.
