Potential of magnesium salt-monoalkylpolyethylene glycol-water systems for use in micellar extraction

摘要

Solubilities in MgCl2 (MgSO4, Mg(NO3)(2))-syntanol DS-10 (syntanol ALM-10)-water systems have been studied by the visual-polythermal method and the isothermal section method. The liquid-liquid phase separation region was shown to change its topology depending on temperature and the salting-out agent. The salting-out agent anion was shown to influence the cloud point of syntanol solutions. The effect of structure on the ability of syntanol to be salted out by magnesium salts was studied. Optimal temperature and concentration parameters of boron extraction in the studied systems were determined.
