| titleOfInvention |
Oil-soluble sulfonate preparation with novel separation step |
| abstract |
OIL SOLUBLE SULFONATES SUITABLE FOR LUBRICATING OIL ADDITIVES ETC. ARE MADE SUBSTANTIALLY FREE OF CORROSIVE SULFATES BY CONTROLLED ADDITION OF WATER TO ALKYL BENZENE SULFONIC ACIDS IN SOLUTION IN A HYDROCARBON SOLVENT, THEREBY SEPARATING A MAJOR PART OF THE ASSOCIATED SULFURIC ACID, THEN NEUTRALIZING WITH EXCESS POWDERED METAL OXIDE, HYDROXIDE OR CARBONATE AND FILTERING TO REMOVE THE EXCESS SOLIDS ON WHICH ARE ADSORBED REMAINING SULFATES. |
