Process for producing highly basic alcium sulfonates |
abstract |
Highly basic Calcium Sulphonate with improved solubility in heavy paraffinic oils and improved filterability is prepared by carbonating a mixture of sulphonic acid, calcium hydroxide, water, alcohol and solvent at a temperature from 20 DEG C to 35 DEG C and using a stoichiometric excess of calcium hydroxide and a specified amount of water. |
