RESUMO
ABSTRACT The activity coefficient at infinite dilution (&IN1) and distribution ratios at infinite dilution (&IN2) were determined for alkanols (methanol, ethanol, 1-propanol, 1-butanol, 2-butanol, and 2-methyl-2-propanol) in the ionic liquid (IL) 1-butyl-3-methylimidazolium methyl sulfate ([BMIM][CH3SO4]) by HS-SPME (Headspace - Solid Phase Micro Extraction) at four temperatures (298.15, 313.15, 333.15, and 353.15K) using headspace - solid phase microextraction (SPME-HS). The results showed significant agreement with literature data. In addition, partial molar excess enthalpies at infinite dilution (&IN3), excess Gibbs energies (&IN4), and excess entropies (&IN5) were calculated from the (&IN6) values.
