<p>The process comprises a first step of esterification of an aminoacid and is characterized by a second step of condensation of a fatty acid chloride with an esterified amino acid derivative. It relates to the synthesis of surfactant compounds of the cationic type comprised of natural dibasic aminoacids (and any of their homologues) which have been conveniently modified in order to obtain products for specific applications such as antimicrobial agents (biocides). Non toxic catalysts and reaction means are used and a final product free of impurities is obtained. The cost is reduced due to the utilization of more economical raw materials and less complex installations.</p> |
