摘要： Disclosed herein is a process for separating phenolic acids, comprising a step a) of contacting a feed containing at least two different phenolic acids (PA) with an extraction solvent to extract the at least two different PAs in a first PA containing liquid. The process also comprises a step b) of contacting the first PA containing liquid with a solid molecular imprinted polymer (MIP), such that the MIP captures a target PA from the at least two different PAs, to thereby form a first PA bound MIP dispersed in a second PA containing liquid, where the second PA containing liquid comprises at least one PA and none or a substantially lesser amount of the target PA originally present in the first PA containing liquid. The process further comprises a step c) of separating the first phenolic acid bound MIP from the second PA containing liquid, and a step d) of separating the target phenolic acid from the first PA bound MIP to obtain a recovered MIP, wherein the recovered MIP is substantially free of the target phenolic acid.

摘要： Methods for production of a bioproduct with a microorganism and selective extraction of bioproducts from a fermentation broth. The methods may include mixing a carbon source, a nitrogen source, and an extractant-depleted raffinate to form a fermentation medium, and fermenting the medium with a microorganism to form a fermentation broth having at least one bioproduct. The bioproduct may be extracted from the fermentation broth with an extractant comprising an olefin to form an extract and a raffinate, and the extract may be further separated from the raffinate. The bioproduct may then be separated from the extract, and the extractant may be separated from the raffinate to regenerate the extract-depleted raffinate.

摘要： This invention relates to a process for preparing succinate ester from a succinic acid salt present in a fermentation broth. In the first stage of this invention, renewable carbon resources are utilized to produce succinic acid in the form of a succinic acid salt through biological fermentation. The succinic acid salt present in the fermentation broth is subjected to double displacement reaction with a strong acid leading to the release of succinic acid. Succinic acid is recovered by fractional crystallization integrated with an alcohol washing step and subjected to esterification reaction to produce succinate ester which is purified by fractional distillation. The succinate ester thus obtained is converted into 1,4-butanediol, gamma-butyrolactone and tetrahydrofuran through hydrogenation reactions. The succinate ester can also be hydrolyzed to yield highly pure succinic acid.

摘要： One embodiment of the invention provides polyisobutylene (PIB) oligormers that are end-functionalized with ruthenium (Ru) catalysts. Such nonpolar catalysts can be dissolved in nonpolar solvents such as heptane, or any other nonpolar solvent that is otherwise not latently biphasic (i.e., if two or more solvent components are present, they remain miscible with each other throughout the entire reaction process, from the addition of substrate through to the removal of product). Substrate that is dissolved in the nonpolar solvent with the catalyst is converted into product. The lower solubility of the product in the nonpolar solvent renders it easily removable, either by extraction with a more polar solvent or by applying physical means in cases where the product precipitates from the nonpolar solvent. In this manner the catalysts are recycled; since the catalysts remain in the nonpolar solvent, a new reaction can be initiated simply by dissolving fresh substrate into the nonpolar solvent.
摘要翻译： 本发明的一个实施方案提供了用钌（Ru）催化剂端官能化的聚异丁烯（PIB）寡聚体。 这种非极性催化剂可以溶解在非极性溶剂如庚烷或任何其他非潜在双相的非极性溶剂中（即，如果存在两种或多种溶剂组分，则它们在整个反应过程中彼此保持混溶， 加入底物通过去除产物）。 用催化剂溶于非极性溶剂的底物转化成产物。 产品在非极性溶剂中的较低溶解度使其易于除去，无论是通过用极性较大的溶剂萃取还是通过在产物从非极性溶剂沉淀的情况下应用物理方法。 以这种方式，催化剂被再循环; 由于催化剂保留在非极性溶剂中，所以可以简单地通过将新鲜的底物溶解在非极性溶剂中来开始新的反应。
