Liquid-liquid equilibria were measured for nine binary systems containing 1-alkyl-3-methylimidazolium hexafluorophosphates with alcohols in the following temperature ranges: BMIM PF6 with 1-propanol or 1-butanol or 1-pentanol and HMIM PF6 with 1-butanol or 1-pentanol from (278.15 to 343.15) K; HMIM PF6 with 1-propanol from (278.15 to 328.15) K; and OMIM PF6 with 1-propanol or 1-butanol or 1-pentanol from (278.15 to 307.15) K, (278.15 to 323.15) K, and (278.15 to 333.15) K, respectively. The equation results were satisfactorily correlated by the NRTL and UNIQUAC models.
