Method Of Producing Gamma Butyrolactone From Biomass

Abstract: An improved method of producing gamma-butyrolactone (GBL) product with high purity in high yield from a starting biomass containing poly-4-hydroxybutyrate (P4HB) and water is disclosed. The method includes recycling a part of GBL product to replace the water to obtain a substantially water-free biomass slurry that is subjected to a conversion process to convert the P4HB to GBL.
