Equilibrium pressures corresponding to the invariant point, clathrate-α-quinol-gaseous guest, and the corresponding clathrate compositions have been measured for methane-quinol in the range 10-25°, and for methyl fluoride-quinol in the range 25-50°. For both guests the fraction of cavities occupied at the invariant point is larger than the value previously observed for small guest molecules, suggesting that the lattice of β-quinol is distorted by the CH4 and CH3F molecules. Enthalpies and entropies of clathration have been calculated. Comparison with theory is possible for the methane clathrate and is reasonably good when either the Lennard-Jones or the Pöschl-Teller potential function is used for the interaction between the guest molecule and the atoms in the wall of the cage.
