Calorimetric determination of enthalpies of solution of slightly soluble liquids II. Enthalpy of solution of some hydrocarbons in water and their use in establishing the temperature dependence of their solubilities

Abstract Enthalpies of solution in water of D 6 -benzene, toluene, ethylbenzene, propylbenzene, and cyclohexane have been determined in the temperature range 288 to 308 K by a flow-microcalorimetric technique. Measurements have also been made for pentane and hexane (at 288 and 298 K) and for benzene (at 308 K). From the results ΔC p values and the partial molar heat capacities for the solutes at infinite dilution have been calculated. Minimum solubility temperatures have also been calculated. Comparison is made between results from solubility measurements and calorimetric measurements for benzene.
