Hargis, D C

A process is described for alkylating aromatic amines comprising the step of reacting (a) an aromatic amine having at least one replaceable hydrogen atom on an amine group or on an aromatic ring carrying an amino group or both, with (b) an alkanol in the presence of a metal oxide alkylation catalyst consisting essentially of at least 70 mole % of Group VII-B metal oxide and no more than about 30 mole % of Group VIII metal oxide so that alkylation of the aromatic amine occurs and so that at least a substantial portion of the alkanol not consumed in the alkylation reaction passes through the alkylation zone undecomposed.
