Synthesis of N-Methylaniline and N,N-Dimethylaniline with Methanol over Alumina Catalyst

Article abstract of DOI:10.1246/bcsj.64.2605

Alumina catalysts prepared by different methods were used for the synthesis of N-methylaniline and N,N-dimethylaniline from aniline and methanol.Al2O3 catalysts prepared from isopropoxide and nitrate showed high activity and JRC-ALO-1 and JRC-ALO-3 supplied by the Catalysis Society of Japan showed low activity.The highest selectivity for N,N-dimethylaniline was 82.8percent with 90.1percent aniline conversion.The catalytic activity of Al2O3 was not poisoned by pyridine and CO2.
