Second Virial Coefficients

The second virial coefficients of the mixtures CH4-C(CH3)4, CH4-Si(CH3)4, and CH4-SF6 have been measured for several compositions and at several temperatures. Values of the coefficients B12, derived from the results, fail to conform to Guggenheim and McGlashan's (1951) extension of the principle of corresponding states. Reasons are given for this disagreement.

Experimental Values

The principle of corresponding states, in a form that makes no reference to any particular equation, is extended to apply to mixtures. The principle, thus extended, is used to calculate the second virial coefficients. of gaseous mixtures. The values so calculated agree with the experimental values nearly always to within 1cm. 3 /mole and often much better.

Second Virial Coefficients

The second virial coefficients of some binary mixtures of organic vapours have been measured at temperatures between 50 and 120° C. Mixtures of n -hexane with chloroform and of n -hexane with diethyl ether show a linear variation of second virial coefficient with composition. This is shown to be in accordance with prediction from the principle of corresponding states. Mixtures of chloroform with diethyl ether show a linear variation at 120° C, but pronounced curvature at lower temperatures. This is interpreted quantitatively as being due to association by hydrogen bonding with an energy of 6020 cal/mole.

A general equation based upon a modified principle of corresponding states and the principle of congruence is used to correlate the second virial coefficients of n-alkanes and their mixtures with each other and with hydrogen. The same procedure is extended to perfluoro-n-alkanes and alk-l-enes.
