PURPOSE: To obtain the titled compound useful as an intermediate for producing drugs, agricultural chemicals, etc., selectively and in high yield, by reacting a specific aromatic amine with a primary or secondary alcohol in the presence of an iron oxide catalyst containing copper oxide and chromium oxide. n CONSTITUTION: An aromatic amine (e.g. aniline, o-tiluidine, p-tiluidine, etc.) containing at least one H in the amino group is reacted with a primary alcohol (e.g. methanol, ethanol, n-propanol, etc.) or a secondary alcohol (e.g. isopropanol, sec-butyl alcohol, etc.) in the presence of an iron oxide catalyst containing copper oxide and chromium oxide to give an N-alkylated aromatic amine. The catalyst is obtained by a method of calcining a mixture of metallic compounds capable of becoming iron oxide, copper oxide and chromium oxide, a method of completely drying the aqueous solution of the mixture and calcining, etc. n COPYRIGHT: (C)1988,JPO&Japio |
