为消除有机溶剂萃取体系的缺点,曾报道过聚乙二醇2000-(NH_4)_2SO_4-H_2O非有机溶剂液-液萃取体系。Петров曾提出安替比林、氯乙酸的水溶液在一定条件下能形成液-液两相。本文研究了安替比林-磺基水杨酸的水溶
To eliminate the disadvantages of organic solvent extraction system, polyethylene glycol 2000- (NH 4) 2 SO 4 -H 2 O non-organic solvent liquid-liquid extraction system has been reported. Петров has proposed antipyrine, aqueous solution of chloroacetic acid under certain conditions can form a liquid-liquid two-phase. This article studies the water-soluble antipyrine-sulfosalicylic acid
