Hydrogen-bonding. Part 22. Characterization of soybean oil and prediction of activity coefficients in soybean oil from inverse gas chromatographic data

Previously reported results on twenty-two gaseous compounds with soybean oil as the stationary gas chromatographic phase have been used to characterize soybean oil in terms of dipolarity/polarizability, hydrogen-bond basicity and lipophilicity. The solubility of these gases in soybean oil has been factored into components that show exactly the compound-soybean oil interactions that favor solubility. The same equation used to obtain this information also can be used to predict the gas chromatographic specific retention volume and then the weight-fraction activity coefficient for numerous other compounds on soybean oil, thus leading to predictions of the solubility behavior of these compounds as bulk liquids with soybean oil.
