Uses

N,N,N'-Trimethylethylenediamine is used as a precursor in the synthesis of a novel gemini surfactant viz. N,N-dimethyl-N-{2-[N'-methyl-N'-(3-sulfopropyl)-alkylammonium]ethyl}-1-alkylammonium bromides. It is also used as an amine component for in-situ formation of alpha-amino alkoxides. Further, it is involved in the synthesis of N,N'-dimethyl-N'-(2-hydroxy-aethyl)-aethylendiamin.

General Description

N,N,N′-Trimethylethylenediamine is synthesized using laser-vaporization supersonic molecular beam. It has been studied using pulsed-field ionization zero electron kinetic energy.

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.
