Abstract

Vapour phase aniline alkylation was carried out over HX, HY, HZSM-5, H-mordenite and over zeolites solid state ion-exchanged with vanadium. Calcination of V2O5-zeolite mixture in nitrogen reduced V2O5 to VO2+ ion and these species migrated into the cationic positions in the zeolite channels. Three-dimensional and mildly acidic zeolites (ZSM-5, Y and X) showed higher catalytic activities for aniline alkylation than did unidimensional and strongly acidic mordenite. Addition of vanadia enhanced the alkylation activity of all the four zeolites studied.
