Abstract
Vapour phase alkylation of aniline with 2-propanol over Li, Na, K, Ca, Sr and Ba ion exchanged zeolites at atmospheric pressure gives N-alkylated and C-alkylated anilines. The N-alkylation selectivity increases with increase in basicity of the zeolite. The major product is the ortho-isomer. The effect of the basic nature of catalyst on the conversion and product selectivity has been evaluated. Co-existence of the acidic and basic sites in the alkali cation exchanged zeolites enhances the N-alkylation rather than the ring alkylation.
