Calcium superbase soaps consist essentially of calcium dissolved in at least one oil in the form of carbonate and of salts of acids, the said acids consisting of a mixture or otherwise of saturated organic carboxylic acids containing from 7 to 13 carbon atoms in which the linear acid content is from 0 to 40% by weight, the content of acids branched on carbon 2 is from 0 to 20% by weight and the content of acids which are mono- or polysubstituted on carbon 3 and/or of higher rank is higher than or equal to 46% by weight. These soaps are used in particular as additives in lubricating oils or as oxidation catalysts. |
