Abstract
The solubilities of chlorodifluoromethane(R-22) and dichlorodifluoromethane(R-12) in organic solvents were measured in the range of low pressures and several temperatures(278-338 K). Organic solvents used in this system were olive oil and oleic acid. Henry`s law is applied in the lower temperature range and the solubilities of R-22 show negative deviations from Raoult`s law. In this study temperature and pressure dependence were correlated. The correlation of gas solubility data, using Krichevsky-Kasarnovsky equation and Van`t Hoff expression are obtained. Values of Henry`s constant, Partial enthalpy and partial entropy in organic solvents have been determined for both gases. The solubilities increase with increasing pressure and decreasing temperature and both gases are more soluble in olive oil than in oleic acid. The solubilities of R-22 in organic solvents were higher than those of R-12 because of hydrogen bonding between solvents and solutes. (author). 11 refs. 7 tabs. 8 figs.
