Abstract
Thermodynamic properties of several organic compounds at infinite dilution in the three phases exhibited by cholesteryl myristate were determined from gas chromatographic data. Activity coefficients for the solutes are reported for the smectic A (74°C), cholesteric (80°C) and isotropic (86°C) phases of the liquid crystal. Excess solution thermodynamic properties are calculated and the results discussed in relation to solute-solvent interactions and orientations of the liquid crystal.
