The central stage of biotechnological production is the transformation of renewable raw materials into bioproducts in a water‐based bioreactor. The fermentation broth usually has a low concentration (less than 10%) of the bioproduct, which requires the application of subsequent separation and purification processes. For many bioproducts, separation is complicated by the presence of non‐ideal thermodynamics or azeotropic points, which makes it impossible to purify the bioproduct by traditional methods, such as conventional distillation. In a search for alternative recovery methods for bioproducts or dehydration of organic mixtures this study proposes an alternative process for the dehydration of acetone by liquid–liquid extraction based on experimental results obtained using an aqueous two‐phase system (ATPS) for an acetone–water–potassium carbonate mixture.

通过水相两相系统的替代性丙酮-水分离工艺

生物技术生产的核心阶段是在水基生物反应器中将可再生原料转化为生物产品。发酵液通常含有低浓度（低于10％）的生物产品，因此需要应用后续的分离和纯化工艺。对于许多生物产品，由于存在不理想的热力学或共沸点，分离过程变得复杂，这使得无法通过传统方法（例如常规蒸馏）纯化生物产品。
