Abstract:
A process is described for producing 1,3-butanediol, wherein an ester of poly-(R)-3-hydroxybutyrate such as formed by transesterification with an alcohol is reduced by hydrogenation in the presence of a skeletal copper-based catalyst to provide 1,3-butanediol. The 1,3-butanediol may be transesterified by reaction with additional poly-(R)-3-hydroxybutyrate ester to produce (R)-3-hydroxybutyl (R)-3-hydroxybutyrate.
