Abstract

Densities of the binary mixtures of organic solvents (acetic acid (HAc), n-butanol (n-BuOH) and n- butyl acetate (n-BuAc)) with 1-ethyl-3-methylimidazolium hydrogen sulphate {[EMIM][HSO4]: IL1}, 1-ethyl-3-methyimidazolium ethyl sul�phate {[EMIM][EtSO4]: IL2}, 1-butyl-3-methylimidazolium acetate {[BMIM] [OAc]: IL3}, 1-butyl-3-methylimidazolium bis (trifluoromethylsulfonyl)imide, {[BMIM][NtF2]: IL4}} and/or Deep Eutectic Solvents (DESs) {choline chloride�acetic acid [ChCl][AA]: DES1}, choline chloride-glycerol [ChCl][Gly]: DES2), were measured over the entire composition range at T (293.15–343.15) K and 1 atm. The volumteric properties and derived thermodynamic properties of mixed solvents were calculated from the experimental data in order to understand the specific interactions and/or non-specific interactions between mixed solvents dur�ing mixing at 298.15 K and 1 atm. Further, the molecular polarity of all the stud�ied components were analyzed using COSMO-RS model
