PURPOSE:To obtain the titled compound useful as a synthetic intermediate for agricultural chemicals, pharmaceuticals, dyes, resin stabilizer, etc., in high yield and selectivity, by reacting an aromatic amine having H at the ortho- position with a primary or secondary alcohol in the presence of a specific catalyst under heating. CONSTITUTION:The objective compound can be produced by reacting an aromatic amine having at least one H atom at the ortho-position (e.g. aniline, o-alkylaniline) with a primary or secondary alcohol (e.g. methanol, isopropanol, etc.) in the presence of a catalyst at 250-450 deg.C in vapor phase. The catalyst is the one containing transition metal oxide (e.g. a catalyst containing iron oxide, etc., as main component) and obtained by calcining a component composed mainly of a transition metal compound at 550-850 deg.C. It has improved durability and long life. |
