Mutual solubilities of 3 methyl 2 butanone-water have been determined analytically for temperatures from - 8 C to 180 C at low pressure and from - 8 C to 90 C at pressures up to 350 MN/m[2]. It is found that this system shows a phase behaviour at elevated pressure similar to that of the homologous system 2 butanone-water. The phase behaviour of the ternary system 3 methyl 2 butanone-water-propanone was studied analytically and optically at ambient pressure at 0 C and 40 C. Liquid-liquid equilibria of the binary system 2 butanol-water were thoroughly studied as a function of temperature and pressure. An hitherto unknown immiscibility phenomenon shown by this system was observed at 1.3.8 MN/m[2] isobar in which a domed curve with an U.C.S.T. is followed by a closed solubility loop having a L.C.S.T. and an U.C.S.T. The phase behaviour of the binary system propanone-carbon disulfide was investigated at - 12 C and - 14 C up to a pressure of 362 MN/m2. The results support an earlier investigation carried out at - 2 C which indicates that increasing pressure, raises the critical solution temperature. For each system above the relations existing among the consolute solution properties are discussed in the light of the observed results. The mutual solubility of the binary system thiodipropionitrile-toluene was studied at atmospheric pressure by a light transmission method. It appears that the demixing curve of this system exhibits a L.C.S.T. inbetween two U.C.S.T.'s over a small concentration range in an open miscibility loop.
