MANUFACTURE OF NOVEL CARRIED COPPER CATALYST AND MANUFACTURE OF N-ALKYLATED AROMATIC AMINE USING SAID COPPER CATALYST

摘要

PURPOSE: To efficiently produce a N-alkylated aromatic amine by forming a catalyst by carrying a specific quantity of each of catalytic components composed of copper, manganese and a rare earth metal on a carrier containing alumina. CONSTITUTION: This catalyst is formed by carrying 0.1-5 wt.% copper and 0.05-8 wt.% in total content of manganese and the rare earth metal expressed in terms of metal to be 5:1 to 1:5 in the weight ratio of the rare earth metal to manganese. The N-alkylated aromatic amine expressed by formula II (each of R<1> and R<2> represents a 1-5C alkyl group or alkoxyl group and each of R<3> and R<4> represents a 1-10C alkyl group or a cycloalkyl group) is produced by allowing an aromatic amine expressed by formula I to catalytically react with an alkanol or the ether in the presence of the catalyst.
