Abstract
This data article is related to the subject of the research article “Extraction of Organic Compounds Involved in the Kinetic Resolution of rac-2-Pentanol from n-Hexane by Imidazolium-based Ionic Liquids: Liquid-Liquid Equilibrium” (Montalbán et al., 2018) [1]. It contains experimental data of density and refractive index of binary and ternary mixtures of imidazolium-based ionic liquids, n-hexane and organic compounds involved in the kinetic resolution of rac-2-pentanol (rac-2-pentanol, vinyl butyrate, rac-2-pentyl butyrate or butyric acid) measured at 303.15 K and 1 atm. These data are presented as calibration curves which help to determine the composition of the ionic liquid-rich phase knowing its density or refractive index.

RX-5000α refractometer from ATAGO and an Anton Paar DMA-4500 vibrating-tube densimeter Raw data Before the measurements, the ionic liquids and the organic compounds were dried under vacuum in the presence of anhydrous phosphorus pentoxide and kept in a desiccator to avoid any moisture absorption The samples were left to equilibrate at 303.15 K for a certain time before an individual measurement University of Murcia, Murcia, Spain, Europe The data are with this article
Density and refractive index calibration plots of mixtures help to determine the composition of the ionic liquid-rich phase of an unknown sample
Summary
The ionic liquids 1-butyl-3-methylimidazolium methylsulphate, [bmimþ ][MeSO4−] (purity 4 0.99), and 1-ethyl-3-methylimidazolium acetate, [emimþ ][Ac−] (purity 4 0.95) were provided from Iolitec. () [emim þ ][Ac−] ([emim þ ][Ac−] mole fraction 1⁄4 −50730 · (refractive index) þ 151977 · (refractive index). Refractive index values (x-axis) correspond to the refractive index of the binary mixtures. (○) n-hexane (n-hexane mole fraction 1⁄4 2.7657 · (density)2 – 6.2963 · (density) þ 3.8019; r2 1⁄4 0.9966); () [bmim þ]. [MeSO4−] ([bmim þ ][MeSO4−] mole fraction 1⁄4 2.7572 · (density)2 – 3.4520 · (density) þ 1.0626; r2 1⁄4 0.9984). Both sets of data (full and empty cycles) correspond to the same experimental run, i.e. density values (x-axis) correspond to the density of the ternary mixtures
