摘要：
HYDROCARBON COMPOUNDS HAVING THE GENERAL FORMULA CNH2N-8, WHERE N IS AN INTEGER FROM ABOUT 10 TO 24, ARE SELECTIVELY REMOVED FROM DETERGENT ALKYLATES BY TREATING THE DETERGENT ALKYLATE WITH AT LEAST 20 PERCENT OLEUM OR SO3 SO AS TO CONVERT CNH2N-8 HYDROCARBON COMPOUNDS TO THEIR ACID DERIVATIVES. THE ACID DERIVATIVES CAN THEN BE SEPARATED FROM THE DETERGENT ALKYLATE.
