Abstract:An n-fluid local composition model is derived for the excess free energy of multicomponent liquid mixtures. Taking into account that differences in fluid structure affect the intermolecular interactions leads to the following expression for a binary mixture:The parameters A ij ) ln γ j ∞ and R ij can be expressed in terms of molecular properties, and the model should therefore have general validity. For most systems tested, the approximation R ij ) 1/R ji is valid. This leads to a three-parameter version that,… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
