Abstract

Because of the similarities in the vapor pressures between hydrocarbons and analogous fluorocarbons some astonishment was occasioned when the vast difference in solvent power came to light towards the end of World War II. One explanation advanced for this difference is that the potential energy per mole i.e., molar energy of vaporization is not very different for hydrocarbon and fluorocarbon, but the internal pressure differs greatly because of size differences. Since the internal pressure is defined as the energy of vaporization per cc., the volume dependence makes size a considerable factor. R. Carbonell in 1956 extended the solubility studies of the fluorocarbons with an M.S. Thesis, Marquette University, under the direction of Dr. S.L. Kittsley. In the present project solubility data will be gathered on systems not previously studied. Further, vapor pressure of both pure and binary systems will be measured as a function of temperature and also composition. Interest on the part of this experimenter stems from previous work dealing with the activity of electrolytes. Presently, the activity of non-electrolytes will be sought with an eye to the possibility of determining thermal quantities e.g. heats of solution.
