| 发明名称 | 3-hydroxypropionic acid compositions | ||
| 摘要 | 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. | ||

| 主权项 | 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 14C 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. | ||
