Liquid-Liquid Equilibrium of Aqueous Mixtures of Poly(Ethylene Glycol) with Na2SO4 or NaCl
Experimental liquid-liquid equilibrium phase diagrams, tie lines, and plait points were obtained for ternary systems consisting of water, sodium sulfate, and poly(ethylene glycol) 1000 at 301 K, poly(ethylene glycol) 3350 at 301 and 308 K, and poly(ethylene glycol) 8000 at 301 K. The equilibrium phase diagram of water, sodium chloride, and poly(ethylene glycol) 8000 at 333 K was also determined.
