A process to produce an aqueous solution of carbohydrates that contains C6-sugar-containing oligomers, C6 sugar monomers, C5-sugar-containing oligomers, C5 sugar monomers, or any combination thereof is presented. The process includes the steps of reacting biomass or a biomass-derived reactant with a solvent system including a lactone and water, and an acid catalyst. The reaction yields a product mixture containing water-soluble C6-sugar-containing oligomers, C6-sugar monomers, C5-sugar-containing oligomers, C5-sugar monomers, or any combination thereof. A solute is added to the product mixture to cause partitioning of the product mixture into an aqueous layer containing the carbohydrates and a substantially immiscible organic layer containing the lactone.
提供一种生产含有C6糖类寡聚体、C6糖单体、C5糖类寡聚体、C5糖单体或其任意组合的碳水化合物水溶液的方法。该方法包括将生物质或生物质衍生物反应于包括内酯和水以及酸性催化剂的溶剂体系中。反应产生一个产物混合物,其中包含水溶性的C6糖类寡聚体、C6糖单体、C5糖类寡聚体、C5糖单体或其任意组合。向产物混合物中添加一种溶质,使产物混合物分配为含有碳水化合物的水层和含有内酯的基本不混溶的有机层。
