The present invention provides a kind of small molecule alcohol fluoride salt aqueous two-phase system and its extraction method, which is characterized in that the aqueous two-phase system includes six fluorine isopropanol, salt and water phase. After extraction, the target was mixed with salt solution, then added six fluoro isopropanol, mixed uniformly and centrifugally, and kept at constant temperature. The system was divided into two phases, the upper phase was water phase, the lower phase was alcohol phase, and the target product was extracted to the next phase. The invention of small molecule alcohol fluoride salt aqueous two-phase system is a new type of ATPS a phase separation ability, good stability, simple phase under mild conditions, the extraction of the target has short extraction time, high extraction efficiency, and has the characteristics of small molecular hydrocarbon enrichment, significantly better than the traditional alcohol salt aqueous two-phase system.

一种小分子氟醇-盐双水相体系及其萃取方法
本专利技术属于液-液萃取
，尤其涉及一种小分子氟醇-盐双水相体系及其萃取方法。
技术介绍
双水相体系是一种或几种物质的水溶液在一定条件下自发形成的两个互不相溶、界面清晰的水相体系。基于双水相体系所发展起来的双水相萃取技术是一种操作简便、条件温和、生物相容性好、环境友好的液-液萃取技术。迄今为止，双水相萃取技术已经被成功应用于生物医药工程领域，如酶和蛋白质、天然植物活性成分、金属离子、抗生素等物质的萃取、分离和纯化。小分子醇-盐双水相体系是一种新型双水相体系，与传统的高聚物-高聚物双水相体系或高聚物-盐双水相体系相比，具有原料成本低、体系粘度低、传质速度快、原料易于回收利用(醇蒸回收醇、结晶回收盐)、不易乳化、可简化操作和降低成本等特点。目前，已报道的常用分相盐多达十几种，而常用的分相醇仅有甲醇、乙醇、正丙醇、异丙醇等小分子碳氢醇，品种较少，并且这些小分子醇的分相能力较弱，需要引入较多的分相盐才能形成双水相体系。因此，发掘新型的分相醇，构建分相能力强﹑萃取效率高的小分子醇-盐双水相体系非常必要。
