| Zusammenfassung: | Methods and systems for producing alkyl hydroxyalkanoate 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. |
