FUNCTIONAL FLUIDS COMPRISING ALKYL TOLUENE SULFONATES

摘要

Provided are formulations, methods of making, and methods of using a functional fluid of the present invention to achieve and maintain optimal frictional characteristics in machines housing that fluid, wherein the functional fluid comprises, among others, a friction-modifying amount of an alkyl toluene sulfonate salt or a mixture of alkyl toluene sulfonate salts.

1. A functional fluid composition comprising an admixture of: (a) a major amount of an oil of lubricating viscosity; and (b) a friction-modifying amount of one or more oil-soluble alkyl toluene sulfonate salts represented by the formula:wherein R1 is a metal sulfonate group and R2 is an alkyl group derived from C20-C24 isomerized linear alpha olefins, wherein about 14% to about 31% of each of the isomerized linear olefins are branched, and further wherein the friction-modifying amount of one or more oil-soluble alkyl toluene sulfonate salts in the functional fluid is about 1.5 wt. % to about 2.5 wt. %.
