The design of a gas solubility apparatus utilizing the basic principle of the Morrison and Billet apparatus is described. The solubilities at atmospheric pressure of ethane in the normal paraffin solvents, hexane, heptane, octane, dodecane and hexadecane, and alm of the same gar in the two-component solvent solutions consisting of hexane and hexadeeane are reported. The solubilities of twelve gases were empirically correlated utilizing one constant for each gas. The empirical equations permit a n estimate of the solubility in any normal paraffin solvent from hexane to hexadecane and for any temperature between 15°C and 40°C from a single solubility measurement. Extrapolation of gas solubilities in normal paraffinsknowledge of the equilibrium solubilities of gases is required for the design of gas-liquid mass transfer equip Because gas solubilities are diffcult to measure accurately, it would be very useful to be able to predict solubilities from a limited number of measurements, and further to extrapolate solubility data from a particular temperature to any other temperature. In their considerable conkibutions to the understanding of solubility, Hilderbrand and Scott(',*) have indicated the possibility of predicting the solubility of a gas in a range of liquids (based on the regular solution theory) and for a range of ternperaturcs, from a single solubility measurement. The application of the regular solution theory for quantitatively predicting gas solubilities in normal paraffins has been only partially succcssful, however, as discussed later. To provide an alternate method for quantitatively estimating gas solubilities in n-paraffins we have formulated a system of empirical equations based on available data and including our own solubility measurements for ethane. These equations appear to represent well all the consistent data available, and should be useful in predicting solubilities to an accuracy of within about 4% (usually better) for any gas for which at least one solubility is known, and for a temperature range at least from 15°C to 40°C. If the logarithm of the (mole fraction) solubility and the logarithm of the absolute temperature could be expected to remain linear, an extrapolation over a widcr temperature range would be possible. Because solubility data are scarce for temperature much below l5OC and much above 4O0C, the accuracy of predictions has not been tested beyond the indicated tenipcrature range.As part of our investigation using n-paraffins, we measured the solubilitics at 2S°C of cthane in hexane, heptane, octane, dodecane and hcxadecanc. To see whether there was some systematic arrangement of gas solubilities in these homologous liquids, we collected from the literature data for various other gases. \ifhen the logarithm of the mole fraction solubility was plotted as the ordinate and the number of carbon atoms in the solvent as tlic absissa, for all the data we obtained, a systematic
