Abstract
Activity and partition coefficients for the polar solutes chloroform, dichloromethane and ethyl acetate at infinite dilution in squalane-dinonyl phthalate mixtures have been determined at 303°K by the extrpolation of measurements made using a vacuum microbalance technique. The results are compared with predictions using the Purnell-Andrade and Tiley-Perry relationships. The effect of solvent-solid support ratios on the determined activity coefficients and the adsorption phenomena involved have been examined. Whereas 20% by weight of solvent yields true bulk liquid activity coefficients for chlorform and dichloromethane, a 40% loading is necessary for ethyl acetate.
