PURPOSE:To obtain the titled compound useful as a synthetic intermediate for agricultural chemicals, pharmaceuticals, dyes, resin stabilizers, 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. 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, impregnating an aqueous solution of the salt of Cr, Al or Mg to the calcined product and again calcining the impregnated product. It has improved durability and long life. |
