  • Publication number: 20230286895
    Abstract: Methods and systems for producing alkyl hydroxyalkanoates from hydroxycarboxylic acid recovery bottoms. The methods generally comprise the steps of obtaining a hydroxycarboxylic acid recovery bottom, adding a mono-alcohol to the hydroxycarboxylic acid recovery bottom to obtain a first mixture, heating the first mixture, optionally in the presence of a catalyst to form a reaction product, distilling the reaction product, and recovering an alkyl hydroxyalkanoate fraction.
    Type: Application
    Filed: May 19, 2023
    Publication date: September 14, 2023
    Applicant: CARGILL, INCORPORATED
    Inventors: Timothy Walter ABRAHAM, Anthony Louis DURAN, Stephen C. EDGAR, Ravi R. GOKARN
