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][HSO 4 ]: IL1 }, 1‐ethyl‐3‐methyimidazolium ethyl sulphate {[EMIM][EtSO 4 ]: IL2 }, 1‐butyl‐3‐methylimidazolium acetate {[BMIM][OAc]: IL3 }, 1‐butyl‐3‐methylimidazolium bis (trifluoromethylsulfonyl)imide, {[BMIM][NtF 2 ]: 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 during mixing at 298.15 K and 1 atm. Further, the molecular polarity of all the studied components were analyzed using COSMO‐RS model.
