Molecular models for 267 binary mixtures validated by vapor–liquid equilibria: A systematic approach
TL;DR: In this paper, a set of simple molecular models for 78 pure substances from prior work is taken to systematically describe all 267 binary mixtures of these components for which relevant experimental VLE data is available.

Prediction of excess properties for liquid mixtures: results from perturbation theory for mixtures with linear molecules
TL;DR: In this paper, a Weeks-Chandler-Andersen type perturbation theory is used to predict excess properties of liquid binary mixtures of spherical and linear dumbbell-like molecules.

Triple-points of low melting substances and their use in cryogenic work
TL;DR: A comprehensive survey of low-melting elements and compounds has been carried out, covering 190 substances from neon to carbon tetrachloride, which span T t values from 24.5 to 250.5 K.
Journal ArticleDOI
Theory of fluids of non-axial quadrupolar molecules
TL;DR: In this paper, it was shown that for pure ethylene, the effective axial approximation gives accurate results for the third order free energy term A 3, and hence, the non-axial expressions correctly reproduce the free energy and pressure second virial coefficient.
Journal ArticleDOI
Thermodynamic properties of binary liquid mixtures of ethane and ethylene with methane and the rare gases
TL;DR: In this paper, two series of binary liquid mixtures containing either ethylene or ethane have been investigated, at one or more temperatures (usually at the triple-point temperature of the component with the higher melting-point).

Determination of Activity Coefficients from total pressure measurements
TL;DR: In this paper, a method of least squares is described for calculating activity coefficients from results of total vapour pressure measurements, and a method for computing activity coefficients is proposed for calculating the activity coefficient from the results of a single measurement.

A rigid sphere model for the melting of argon
H.C. Longuet-Higgins,B. Widom +1 more
TL;DR: In this paper, the repulsive forces are represented by rigid cores and the attractive forces by a uniform background potential which depends on density but not on temperature, and it is shown that the structure of liquids and solids near the triple point is mainly determined by the repulsion forces, with the attraction forces serving merely to keep the molecules together.

Theory of intermolecular pair correlations for molecular liquids. Applications to the liquids carbon tetrachloride, carbon disulfide, carbon diselenide, and benzene
TL;DR: In this article, the reference interaction site model (RISM) is used to describe the intermolecular structures of the liquids carbon tetrachloride, carbon disulfide and carbon diselenide.
Journal ArticleDOI
Statistical thermodynamics of mixtures of molecules of different sizes
TL;DR: In this paper, it was shown that an approximation of the type originally suggested by van der Waals is superior to approximations based on the concept of random mixing, and the recommended approximation was confirmed by comparison with experiment.
