DERIVING THE EQUATION OF STATE FOR LIQUIDS AND EXTENSION OF THE PRINCIPLE OF CORRESPONDING STATES
A new simple model is introduced for a liquid and an equation of state is derived based on this model and the statistical mechanical calculations. This equation of state works well for the non-polar and slightly polar liquids. The important conclusion that may be deduced from this equation of state is that if the reduced variables of state are chosen and defined appropriately, then, the pri...

متن کاملLiquid Density of Alkanes and Halogenated Alkanes Mixtures in a Corresponding States Format
The Corresponding States (CS) density models for mixture proposed here, one for saturated and one for compressed liquid, are analytically similar to the pure fluid liquid density exposed in the former paper, but now with critical constants and 8,, replacing wm , as from the mixing rules. The mixing rules present two adjustable interaction coefficients for each binary pair, but they are set to u...
متن کاملViscosity minima in binary mixtures of ionic liquids + molecular solvents.
The viscosity (η) of four binary mixtures (ionic liquids plus molecular solvents, ILs+MSs) was measured in the 283.15 < T/K < 363.15 temperature range. Different IL/MS combinations were selected in such a way that the corresponding η(T) functions exhibit crossover temperatures at which both pure components present identical viscosity values. Consequently, most of the obtained mixture isotherms,...
متن کاملGeneralized corresponding states model for bulk and interfacial properties in pure fluids and fluid mixtures
We have formulated a general approach for transforming an analytical equation of state ~EOS! into the crossover form and developed a generalized cubic ~GC! EOS for pure fluids, which incorporates nonanalytic scaling laws in the critical region and in the limit r→0 is transformed into the ideal gas equation EOS. Using the GC EOS as a reference equation, we have developed a generalized version of...
