CA 2092183

Disclosed is a process for manufacturing a linear glucamide surfactant comprising reacting an N-alkylglucamine, e.g., N-methylglucamine, a fatty ester, e.g. coconut oil in the presence of a phase transfer agent, generally a nonionic surfactant, preferably a preformed product of the process, the reaction preferably being conducted in the presence of an alkaline catalyst.

L'invention porte sur une méthode pour produire un surfactif à base de glucamide linéaire, consistant à faire réagir une N-alkylglucamine, p. ex. la N-méthylglucamine et un ester gras, p. ex. de l'huile de noix de coco, en présence d'un agent de transfert phasique, généralement un surfactif non ionique et de préférence un produit préformé du procédé; on privilégie dans cette réaction la présence d'un catalyseur alcalin.
