Abstract
The statistical‐mechanical description of clathrate compounds of quinol with non‐polar gases is discussed on the basis of the Lennard‐Jones and Devonshire model. Formulae are given for the equilibrium vapour pressure of the gaseous component and for the chemical potential of the quinol in the clathrate. From the formulae it appears that the concentration of the gas in a quinol clathrate, which is simultaneously in equilibrium with solid α‐quinol and a gas phase, is independent of the nature of the gas.An experimental method is described for determining the vapour pressure and the composition of the clathrate at the above three‐phase equilibrium. Results are given for the compound with argon. The limited number of experimental data on vapour pressures and heats of mixing at present available seems to support the theory.Keywords
