  • METHOD OF PRODUCING GAMMA-BUTYROLACTONE FROM BIOMASS
    Publication number: 20230313238
    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.

  • Production of salts of 4-hydroxybutyrate using biobased raw materials
    Patent number: 11111202
    Abstract: Gamma-butyrolactone (“GBL”) and Gamma-hydroxybutyrate (“GHB”) having a unique carbon footprint as defined by the percent modern carbon (pmc) are described herein. The percent modern carbon can be controlled by varying the amounts of biobased, renewable starting materials and petroleum-based starting materials to prepare GBL or GHB having a defined pmc or by preparing mixtures of GBL or GHB prepared from biobased renewable starting materials and GBL or GHB prepared from petroleum-based starting materials.
