The excess Gibbs free energies, enthalpies, entropies, and volumes are reported for mixtures of ethylene diamine-ethylene glycol at 25°C. The refractive indices of these liquid mixtures are also reported for 25°C.The excess thermodynamic properties have been reported for water-diethylamine solutions at 49.1°C, and ethyl alcoholdiethylamine solutions at 50°C. In both mixtures the excess enthalpies are large and negative over the entire composition range. The same is true for the TsE values. However, the Gibbs free energies are much smaller, and are also of opposite
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.
