ABSTRACT:
Aliphatic hydrocarbon-substituted sulfonic acids, sulfonyl chlorides, amino sulfonic acids, sulfonamides and alkaline earth metal salts of such acids whose hydrocarbon substituent has an average molecular weight in the range of 300 to 200,000 are novel, useful compounds readily prepared through reaction of chlorosulfonic acid with a polymeric hydrocarbon having at least one carbon to carbon double bond as in the liquid to solid polypropene and polybutene or copolymer of two or more C.sub.2 to C.sub.6 unsaturated hydrocarbons having said average molecular weight. Such sulfonic acids, sulfonyl chlorides, amino sulfonic acids, sulfonamides and alkaline earth metal salts of the acid are soluble in hydrocarbon feeds (i.e., gasoline, diesel and heating fuels) and in lubricating oils as are the alkaline earth metal salts of such acids.
