ABSTRACT:
The selective ring-alkylation of anilines comprising providing a mixture of a lower alkanol and an aniline, exposing said mixture to a temperature of from 300.degree. C. to 500.degree. C., preferably from 350.degree. C. to 450.degree. C., in the presence of an acidic Y-type zeolite is described. The Y-type zeolites are predominantly selective to the formation of para-alkylanilines.
