The synthesis of phenol sulfonate esters of alkanoyl amino acids is conducted in the presence of aqueous base to provide bleach activator compounds. Thus, the acid chloride of N-nonanoyl-6-aminocaproic acid is reacted with the sodium salt of p-phenol sulfonate in the presence of water at a pH in the range of about 9 to about 12 to yield the corresponding phenol sulfonate ester. The synthesis of the phenol sulfonate ester of the monononyl amide of adipic acid is also illustrated.

On réalise la synthèse d'esters phénoliques de sulfonates d'acides aminés d'alcanoyle en présence d'une base aqueuse afin d'obtenir des composés d'activation du blanchiment. On fait donc réagir le chlorure d'acide de l'acide N-nonanoyl-6-aminocaproïque avec le sel de sodium phénolique de sulfonate-p en présence d'eau avec un pH compris entre environ 9 et 12 afin d'obtenir l'ester phénolique de sulfonate correspondant. On décrit également la synthèse de l'ester phénolique de sulfonate de l'amide monononyle d'acide adipique.
