A simple method for N-alkylation of 1, 2-diaminoethane with different alcohols in a fixed-bed reactor using cheap CuO-NiO/γ-Al2O 3 as the catalyst has been developed. The present catalytic system was applicable in the N-alkylation of 1, 2-diaminoethane with both primary and secondary alcohols. Mono-N-alkylation of 1, 2-diaminoethane with low-carbon alcohols resulted in high yields; the yields of tetra-N-alkylation of 1, 2-diaminoethane with low-carbon alcohols declined markedly with the increase of the molecular volume of alcohols.

Page/Page column 7; 8, (2010/02/11)
PROBLEM TO BE SOLVED: To provide a method for producing an N-monoalkyl-substituted alkylene amine especially useful for uses such as medicine intermediates, agrochemical intermediates, urethane resin-foaming catalysts, surfactants and the like among alkyl-substituted alkylene amine compounds from an alcohol and an alkylene amine as raw materials. SOLUTION: This method for producing the N-monoalkyl-substituted alkylene amine is characterized by reacting the alkylene amine with a ≥2C alkyl alcohol in the presence of a copper-containing oxide catalyst system. The N-monoalkyl-substituted alkylenamine is produced in high conversion and in N-monoalkylation selectivity.
