PROCESS FOR PRODUCING (R)-3-HYDROXYBUTYL (R)-3-HYDROXYBUTYRATE
-
Page/Page column 7; 8, (2014/09/29)
A process for the production of (R)-3-hydroxybutyl (R)-3-hydroxybutyrate comprising: i) contacting poly-(R)-3-hydroxybutyrate with an alcohol to transesterify the poly-(R)-3-hydroxybutyrate under transesterification conditions to produce an ester of (R)-3-hydroxybutyrate and the alcohol; ii) separating the product of step i) into a first and second portion and reducing the first portion of the (R) 3-hydroxybutyrate ester to form (R)-1,3-butanediol; and iii) contacting under transesterification conditions the (R)-1,3-butanediol from step ii) with the second portion of the transesterified ester to produce (R)-3-hydroxybutyl-(R)-hydroxybutanoate.
