Liquid−Liquid Equilibria for Random Copolymer of Ethylene Oxide + Propylene Oxide + Salt + Water

Liquid−liquid equilibria of aqueous two-phase systems composed of aqueous solutions of random copolymer of ethylene oxide + propylene oxide and various salts were measured. The salts used were Na2SO4, K2HPO4, KH2PO4, and the mixture of K2HPO4 + KH2PO4. The effect of temperature on liquid−liquid equi...

Description
Summary:Liquid−liquid equilibria of aqueous two-phase systems composed of aqueous solutions of random copolymer of ethylene oxide + propylene oxide and various salts were measured. The salts used were Na2SO4, K2HPO4, KH2PO4, and the mixture of K2HPO4 + KH2PO4. The effect of temperature on liquid−liquid equilibria is discussed.
