Density and Molar Volumes of 1-Butyl-3-methylimidazolium trifluoromethanesulfonate and Methanol Mixtures at Ambient and Saturated Pressures

In this work, we present the density of 1-butyl-3-methylimidazolium trifluoromethanesulfonate and methanol binary mixtures (1 − x )CH 3 OH + x [BMIM][TFO], at ambient and saturated pressures ρ (p_0 or s ,T,w) /kg·m −3 , temperatures of T = (278.15 to 413.15) K, and w = (0 to 100) mass percent [or x = (0 to 1) mole fr.]. Measurements were made with an estimated Δ ρ / ρ = ± 0.03
