Beschreibung
Zusammenfassung:	On produit du sulphonate de calcium basique thixotropique par un procédé consistant à carboner un mélange d'alcool contenant 1 à 4 atomes de carbone, un solvant d'hydrocarbure organique volatil, un oxyde de calcium ou un hydroxyde de calcium, facultativement de l'eau et un mélange d'acides sulfoniques d'alkyle-aryle dans lequel la distinction des groupes alkyle dans les acides sulfoniques va au moins de 12 à 24 atomes de carbone. L'emploi du mélange d'acides sulfoniques d'alkyle-aryle permet la production de sulfonate de calcium thixotropique amélioré sans que l'on ait besoin d'un promoteur réactionnel supplémentaire. Ce produit est utile dans des revêtements anticorrosion. Thixotropic basic calcium sulphonate comprising carbonating a mixture of C1 to C4 alcohol, a volatile organic hydrocarbon solvent, calcium oxide or calcium hydroxide, optionally water and a mixture of alkyl aryl sulphonic acids in which the distinction of the alkyl groups in the sulphonic acids span at least from C12 to C24. Use of the mixture of alkyl aryl sulphonic acids enables production of improved thixotropic calcium sulphonate without the need for additional reaction promoter, the product is useful in anticorrosion coatings.
