摘要：
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. (C) 1998 Elsevier Science B.V.
