摘要：
Methylation of aniline forms a range of products varying from N-alkylated to C-alkylated compounds. ALPOs and substituted ALPOs facilitate N-alkylation whereas ZSM-5 catalyse both C- and N-alkylations. ZSM-5 catalyst forms only mono methylated products. Both mono and di methylated products are formed with SAPOs and ALPOs. KY and CsY catalyse only mono methyl aniline formation. Conversions are high with ZSM-5, KY and CsY. Mechanism of reaction is proposed.
