HYDROCARBON FLUIDS WITH IMPROVED POUR POINT

摘要

The addition of alkyl salicylic acids and esters represented by Formula I where R1═H or C12 to C22 linear alkyl group; R2═H or linear C12 to C22 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.
