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.

Second Virial Coefficients

The second virial coefficients of binary mixtures of cyclo hexane with diethylamine, acetonitrile and acetone have been measured at 53 and 76° C. The experimental results are in fair quantitative agreement with a theoretical treatment based on the hypothesis that the polar vapours are partly associated.
