Abstract
Official abstract text for this publication.
Methods and systems for producing high purity 3-hydroxypropionic acid (3-HP) from an aqueous medium, such as a fermentation broth, are described. Aqueous 3-HP solution can be purified by flash evaporation wherein the 3-HP is vaporized at an elevated temperature without conversion to acrylic acid. This process can be integrated with downstream processes for producing other chemical and consumer products.
First claim
Opening claim text (preview).
What is claimed is: 1. A composition comprising nonaqueous components that are at least about 90% by weight of a biologically produced 3-HP, wherein said 3-HP has a 14 C concentration of at least 1 part per trillion carbon and wherein said composition consists essentially of about 1 to about 60% water by weight and about 40% to about 99% nonaqueous components. 2. The composition of claim 1 , wherein said 3-HP has a 14 C concentration of about 1.2 parts per trillion carbon. 3. The composition of claim 1 , wherein said nonaqueous components comprise at least about 95% by weight of said biologically produced 3-HP. 4. The composition of claim 1 , wherein said nonaqueous components comprise at least about 98% by weight of said biologically produced 3-HP. 5. The composition of claim 1 , wherein said composition comprises less than about 30% water by weight. 6. The composition of claim 1 , wherein said composition comprises less than about 10% by weight of acrylic acid. 7. The composition of claim 1 , wherein said composition comprises less than about 5% by weight of acrylic acid. 8. The composition of claim 1 , wherein said composition comprises less than about 1% by weight of acrylic acid. 9. A downstream chemical product produced from the composition of claim 1 , wherein said downstream chemical product is selected from the group consisting of acrylic acid (AA), 1,3-propanediol, methyl acrylate, acrylamide, propiolactone, ethyl-3-3-HP, malonic acid, acrylonitrile, butyl acrylate, 3-HP amide, and ethyl acrylate. 10. A consumer product produced using the downstream chemical product of claim 9 . 11. The consumer product of claim 10 , wherein said consumer product comprises a downstream chemical product with a 14 C concentration of at least 1 part per trillion carbon.
