PRODUCTION OF AMIDOAMINOMONOCARBOXYLIC ACID COMPOUND AND SURFACTANT COMPOSITION CONTAINING THE SAME

Title:

PRODUCTION OF AMIDOAMINOMONOCARBOXYLIC ACID COMPOUND AND SURFACTANT COMPOSITION CONTAINING THE SAME

Document Type and Number:

Japanese Patent JPH1135537

Kind Code:

A

Abstract:

To provide a method for producing the subject high-purity compound free from diamides and polyacrylic acid as impurities through a cyclic amidine formed by reaction between an aliphatic nitrile and a diamine.

First, a cyclic amidine compound is prepared by reaction between an aliphatic nitrile and a diamine in a molar ratio of 1:(1-3) in the presence or absence of a catalyst while eliminating ammonia. Subsequently, the cyclic amidine is hydrolyzed in the presence of an alkali catalyst or in the absence of catalyst into an amidoamine compound, which, in turn, is reacted with 1-3 molar times, based on the cyclic amidine compound, of (1) a halocarboxylic acid, (2) an acrylic lower alcohol ester or (3) acrylonitrile, thus obtaining the objective aminoamidomonocarboxylic acid compound.
