Solubility data were determined experimentally for the following pairs of liquids: 1-butanol-water, benzene-water, methanol-hexane, pentane-water, toluene-water, 1,2-dichloroethane-water, and methylene chloride-water, employing equipment normally used to obtain liquid-liquid equilibrium data. The equipment was composed of three identical linked cells kept at constant temperature by a thermostated water bath. The temperature range from 5.8 degrees to 78.4 degrees C was covered. The effect of temperature on solubility in water was evaluated and discussed. For the systems studied, it was concluded that, unexpectedly, increasing temperature does not raise the mole solubility fraction of methylene chloride in water.
