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.

Claim (Index 1):
A method for producing an alkyl hydroxybutyrate, comprising:\n a) obtaining a hydroxybutyrate containing composition, comprising:\n (i) at least 40 percent by weight hydroxybutyrate equivalents; \n (ii) greater than 0 and less than 45 percent by weight free hydroxybutyrates; \n (iii) at least 1 percent by weight saccharide equivalents; and \n (iv) less than 15 percent by weight water; \n b) mixing a C1 to C6 mono-alcohol in a molar ratio of from about 1.1 to 1.0 to about 10.0 to 1.0 of mono-alcohol to hydroxybutyrate equivalents present in the hydroxybutyrate containing composition to obtain a first mixture; c) heating the first mixture to form a reaction product; d) distilling the reaction product and recovering an alkyl hydroxybutyrate fraction comprising:\n (i) at least 90 percent by weight alkyl hydroxybutyrate; \n (ii) less than 1 percent by weight hydroxybutyric acid; \n (iii) less than 1 percent by weight water; and \n (iv) less than 0.5 percent by weight saccharide equivalents.
