Disclosed are methods or processes of synthesizing building blocks and feedstocks for producing a broader range of polymers, including renewable polymers, from renewable resources such as CO.sub.2. In a process of manufacturing a renewable feedstock for polymer production, a CO.sub.2 derived lactone is prepared and processed to form the renewable feedstock. The process may include alkoxycarbonylation of the CO.sub.2 derived lactone to form a diester and hydrogenation of the diester.

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.
