ABSTRACT:
Aromatic amines are alkylated by reaction with an alcohol in the presence of a Group V-B metal oxide alkylation catalyst, preferably a major proportion of a Group V-B metal oxide such as V.sub.2 O.sub.5 in combination with a minor proportion of an A-subgroup metal oxide such as SnO.sub.2, 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.
