The thermodynamic excess properties of binary mixtures: I. Hexanol-1+o-xylene

摘要

The Grunberg-Nissan type interaction parameters have been used to treat volumetric and viscometric excess function data. Calculations have been made easier by using the reduced excess functions. The composition and temperature dependencies of the interaction parameters were found to depend on the nature of the dominant constituent. Using the Eyring theory of viscosity and the ERAS model, the reduced excess viscosity was equated with the Gibbs energy of mixing. A two-term Guggenheim Polynomial was used to explain the composition dependence of the excess functions.
