Abstract
Processes and methods for making ultra-pure (>99.50% by weight), biobased crotonic acid, gamma-butyro lactone, acrylic acid and delta-valerolactone from renewable carbon resources are described herein.
Claims52
A process for the production of an ultra-pure, biobased gamma-butyrolactone product, comprising
- a) combining a genetically engineered biomass comprising polyhydroxyalkanoate polymer, a solvent and optionally a catalyst;
- b) mixing the biomass and solvent together while optionally applying heat;
- c) separating the organic and aqueous phases of the biomass and solvent mixture;
- d) removing the solvent from the biomass;
- and
- e) converting the biomass comprising polyhydroxyalkanoate to a biobased chemical product;
- wherein the weight percent biobased chemical in the product is greater than 95% and wherein the product does not comprise acetamide, n-methyl pyrrolidone or n-ethyl pyrrolidone and fatty acids.
