A hazy dispersion of a calcite-containing sulfonate detergent in oil is clarified by a process including the steps of: a) adding to the dispersion at least one acidifying compound selected from the group consisting of carbon dioxide; sulfur dioxide; organosulfonic acids having a molecular weight of at least 400; and organic carboxylic acids, diacids and anhydrides, containing at least 7 carbon atoms, b) reacting the dispersion in the presence of the acidifying compound, water, and at least one volatile organic solvent, and c) removing volatiles from the so-reacted dispersion by vaporization.
La présente invention concerne la clarification d'une dispersion brumeuse d'un détergent sulfonate contenant une calcite. Ce processus consiste: (a) à ajouter à la dispersion au moins un composé acidifiant sélectionné dans le groupe constitué de dioxyde de carbone, dioxyde de soufre, des acides organosulfoniques possédant un poids moléculaire d'au moins 400, des acides carboxyliques organiques, des diacides et des anhydrides, contenant au moins 5 atomes de carbone, (b) à faire réagir cette dispersion en présence du composé acidifié, d'eau et d'au moins un solvant organique volatil et (c) à retirer les éléments volatils de cette dispersion ayant ainsi réagi par vaporisation.
