Activity and partition coefficients for the polar solute diethyl ether at infinite dilution in squalane and dinonyl phthalate solvent mixtures have been determined at 303°K by the extrapolation of measurements made using a vacuum microbalance technique. The results are compared to predictions using the Purnell-Andrade and the Tiley-Perry relationships. The effect on the activity coefficients resulting from various solvent-solid support ratios has also been investigated.
