Topological investigations of binary mixtures containing 1-ethyl-3-methylimidazolium tetrafluoroborate and anilines

► ρ, u and HE of [emim][BF4] + A or MA or 2MA mixtures have been measured. ► The observed ρ and u data have been employed to determine VE and κSE. ► Topology of the constituents of mixtures has been utilized (Graph theory) to predict VEHE and κSE data of the investigated mixtures. ► Thermodynamic data of the various mixtures have also been analyzed in terms of Prigogine-Flory-Patterson (PFP) theory.
