The purpose of the present invention is to provide organometallic salt compositions that are useful as lubricant additives and/or in lubricant additive compositions to reduce friction and wear, and also have improved solubility in all four types of hydrocarbon base oils (Groups I-IV) at a variety of concentrations and under a variety of conditions. The organometallic salt composition is derived from at least one long chain monocarboxylic acid and a single metal in combination with at least one short or medium branched-chain monocarboxylic acid. The compositions are particularly useful in combination with activated complexes comprising a first metal component, a second metal component and particles comprising the first metal component.

The present invention provides a method for preparing rhodium (III) 2-ethylhexanoate solutions which supplies the reaction product with higher space yield, as well as lower sodium and chloride ion content. An aqueous solution of an alkali salt of 2-ethylhexanoate is thereby initially converted with a rhodium (III) precursor. The rhodium (III) precursor is selected from rhodium (III) chloride solution, rhodium (III) chloride hydrate, and rhodium (III) nitrate. The mixture is heated for several hours. After cooling to room temperature, the rhodium (III) 2-ethylhexanoate formed is extracted from the aqueous solution with an alcohol that is immiscible in water or a carboxylic acid that is immiscible in water, and optionally washed with aqueous mineral acid. The rhodium (III) 2-ethylhexanoate solution obtainable in this way may be used directly as catalyst in hydroformylation reactions.
