Abstract
Embodiments of the present invention are directed to processes for the production of (R)-3-hydroxybutyl (R)-3-hydroxybyrate. Poly (R)-3-hydroxybyrate is transesterified with an alcohol, to form a first ester portion and a second ester portion. The first ester portion is reduced to the diol to form a diol portion and the diol portion is reacted with the second ester portion to produce (R)-3-hydroxybutyl (R)-3-hydroxybyrate.
