Zusammenfassung: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.
