HYDROCARBON FLUIDS WITH IMPROVED POUR POINT

摘要

The addition of alkyl salicylic acids and esters represented by Formula I (I) where R1= H or C12 to C22 linear alkyl group; R2 = H or linear C12toC22 carbonyl group; and R3 = linear C12 to C22 alkyl group reduces the pour point of a hydrocarbon base oil. Thus, both a method for reducing the pour point of hydrocarbon oils and lubricating composition containing pour point reducing salicylates are provided. The hydrocarbon base oil in such method and composition preferably is a Group III base oil.
