The partition behavior of aqueous and organic ternary solutions into two immiscible phases at ambient temperatures was studied. A classification system of the types of materials which phase partition water and organic solvents was developed and a comprehensive list of systems for which phase diagram information is available in the literature has been presented. / Systems in three different classes of materials were studied. Equilibrium phase diagrams, tie-lines and plait points were generated for the ternary systems: poly(ethylene glycol)-1,000/sodium sulfate/water at 28$ sp circ$C; poly(ethylene glycol)-3,350/sodium sulfate/water at 28$ sp circ$C and 35$ sp circ$C; poly(ethylene glycol)-8,000/sodium sulfate/water at 28$ sp circ$C; poly(vinyl alcohol)/methylcellulose/water at 25$ sp circ$C; and poly(propylene glycol)/polystyrene/cyclohexane at 25$ sp circ$C. All measurements were done at 1 atm. The influence of temperature and polymer molecular weight on the shape and location of the equilibrium phase cure and the location of the critical point was analyzed for the poly(ethylene glycol)/sodium sulfate/water system.
