Abstract

Procédé pour extraire une matière non tensio-active d'une charge de départ constituée d'eau, de matière organique sulfatée ou sulfonée et de matière non tensio-active. On soumet la charge de départ à une extraction en utilisant comme seul solvant une cétone en C4 à C10 , à une température inférieure à 60 degrés C, ou un acétate d'alcoyle de C 1 à C6 de manière à former un extrait constitué de cétone ou d'acétate et de matière non tensio-active et un raffinat constitué de cétone ou d'acétate, d'eau et de matière organique sulfatée ou sulfonée et éventuellement on sépare la cétone ou l'acétate de l'extrait et/ou du raffinat. Les procédés pour la préparation de détergents anioniques donnent habituellement un produit contenant de l'eau, un détergent anionique et une matière non tensio-active. Il est souhaitable d'éliminer cette matière non tensio-active.
