The process comprises a first step of esterification of an amino acid, and is characterized in that, in a second step, the condensation takes place of a fatty acid chloride with an esterified amino acid derivative. It relates to the synthesis of cationic type surfactant compounds consisting of natural basic-character amino acids (and any of their homologs) suitably modified for the purpose of obtaining products having specific applications as antimicrobial (biocidal) agents. Nontoxic reaction media and catalysts are used, and a final product free from impurities is obtained. The cost is reduced due to the use of cheaper starting materials and simpler equipment.

Le procédé comprend une première étape d'estérification d'un aminoacide et se caractérise par une seconde étape de condensation d'un chlorure d'acides gras avec un dérivé d'aminoacides estérifiés. Elle concerne la synthèse de composés tensioactifs du type cationique constitués par des aminoacides dibasiques naturels (et n'importe lequel de leurs homologues) modifiés avantageusement dans le but d'obtenir des produits pour des applications spécifiques en tant qu'agents antimicrobiens (biocides). On utilise des moyens de réactions et des catalyseurs non toxiques et on obtient un produit final exempt d'impuretés. Le coût est réduit en raison de l'utilisation de matières premières plus économiques et d'installations plus simples.
