One of the most interesting biobased product developments is the use of metathesis catalysts to rearrange fatty esters. Metathesis chemistry has been known for decades, as has the potential to rearrange fatty esters to diesters and olefins, but Elevance Renewable Sciences has developed their proprietary metathesis technology to an advanced state.

The company and its partner Wilmar International has  just announced the shipment commercial specialty products from their plant in Gresik, Indonesia.  The feedstock is palm oil. Products are expected to to go into detergents and cleaners and personal care. Others include lubricants and additives, engineered polymers; lubricant base oils with improved stability and fuel economy; and unique monomers for bio-based polymers and engineered plastics, including long chain polyamides, polyurethanes and polyesters.

(Reporter's comment: Tall oil fatty acid would not be a preferred feedstock because it would have to be first converted to the methyl ester, and catalyst poisons would have to be removed.)
