ABSTRACT:
An improved method for synthesizing a hydrocarbon soluble (RCOO).sub.3 Cr 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.sup.+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.
