	abstract = {<p>Sn-MFI molecular sieves (Tin silicalite-1) with SiO(2)/SnO(2) molar ratio of 50-150 were synthesized and characterized. Elemental analysis, XRD and DRUV-vis confirmed that prepared samples were of MFI zeolite structure and Sn was incorporated in MFI framework. Vapor phase methylation of aniline over Sn-MFI was systematically studied and optimizations of process parameters were carried out. Sn-MFI (SiO(2)/SnO(2) = 50) was found to be optimum catalyst with 55\% aniline conversion and 60\% N-methylaniline selectivity. At lower space velocity (higher contact time) of 1 h(-1), aniline conversion was found to be increased to 71\% with reduction in N-methylaniline selectivity to 39\% and increased in N,N-dimethylaniline selectivity to 58\%. The reaction follows first order kinetics with respect to aniline having activation energy of 7.3 kcal/mol.</p>},
