Tri-substituted, hydrocarbon soluble, chromium compound synthesis

摘要

An improved method for synthesizing a hydrocarbon soluble (RCOO)3Cr chromium compound is described. The disclosed method employs a two-step reaction scheme utilizing a nonhalogenated chromium compound such as chromic acid anhydride as a starting material. In the first step the chromium source is reduced with an alcohol in the presence of a fatty acid to Cr+3. The synthesis is completed by converting the reduced chromium to the tri-substituted compound by reaction with a fatty acid in the presence of a base. The chromium containing product has particular utility as a corrosion inhibiting fuel soluble additive.
