RT info:eu-repo/semantics/article T1 Experimental and molecular modeling study on the binary mixtures of [EMIM][BF4] and [EMIM][TFSI] ionic liquids A1 Trenzado, José Luis A1 Rodríguez, Ylenia A1 Gutiérrez Vega, Alberto A1 Cincotti, Alberto A1 Aparicio Martínez, Santiago K1 Ionic liquids K1 Mixtures K1 Intermolecular forces K1 Thermodynamics K1 Molecular simulation K1 Química física K1 Chemistry, Physical and theoretical AB The properties of [EMIM][BF4] + [EMIM][TFSI] double salt ionic liquid (DSIL) were studied as a function ofmixtures composition and temperature. Experimental physicochemical properties combined with molecularsimulation (quantum chemistry and classical molecular dynamics) were considered, thus providing amicro and macroscopic characterization of fluids’ structuring, intermolecular forces and molecular aggregation.The results were analysed in thermodynamics terms considering deviations of ideality and mixingproperties as well as from the solvation and interaction between the involved ionic liquids by the developedcomplex hydrogen bonding networks. Likewise, liquid [EMIM][BF4] + [EMIM][TFSI] interfaces(x[EMIM][BF4] = x[EMIM][TFSI] = 0.5) were also studied using molecular dynamics methods to examine the diffusionof [BF4]- and [TFSI]- anions in the [EMIM][BF4] + [EMIM][TFSI] liquid interface, and the mechanismof interface crossing. The results allow a multiscale characterization of the considered ionic liquid mixturesthus providing another way of designing IL-type solvents for specific applications, by choosingnot only the ion identity but also the ion ratio.
