The development of van der Waals cubic equations of state and their application to the correlation and prediction of phase equilibrium properties is presented and analyzed in this paper, with a brief account of the contributions to equation of state development during the years before van derWaals.Abstract:
The development of van der Waals cubic equations of state and their application to the correlation and prediction of phase equilibrium properties is presented and analyzed. The discussion starts with a brief account of the contributions to equation of state development during the years before van der Waals. Then, the original equation proposed in the celebrated thesis of van der Waals in 1873 and its tremendous importance in describing fluid behavior are analyzed. A chronological critical walk through the most important contributions during the first part of the 1900s is made, to arrive at the proposal that I consider to be the most outstanding since van der Waals: the equation proposed by Redlich and Kwong in 1949. The contributions after Redlich and Kwong to the modern development of equations of state and the most recent equations proposed in the literature are analyzed. The application of cubic equations of state to mixtures and the development of mixing rules is put in a proper perspective, and the ...read more

Deep Eutectic Solvents: Physicochemical Properties and Gas Separation Applications
TL;DR: Deep eutectic solvents (DESs) have been considered as alternatives to ILs that maintain most of their relevant properties, such as task-specific character, and at the same time avoid some of their problems, mainly from economic and environmental viewpoints as discussed by the authors.

Critical Properties and Normal Boiling Temperature of Ionic Liquids. Update and a New Consistency Test
TL;DR: In this article, the group contribution method was extended to estimate the critical properties of ionic liquids, and an additional test for determining the consistency of the estimated properties is proposed, which includes the calculation of the saturation pressure at the normal boiling temperature using an equation of state and an accurate model.
