Abstract: Coexistences curves of liquid–liquid phase transition were reported for the binary solutions of the room temperature ionic liquid (RTIL) 1-octyl-3-methylimidazolium hexafluorophosphate ([C8mim][PF6]) with 1-propanol or tert-butanol. The critical amplitude B and the critical exponent β corresponding to the coexistence curve were deduced and the values of β were found to be consistent with the 3D-Ising value. Asymmetry of the diameters for the coexistence curves were examined and discussed in the frame of the complete scaling theory. [Copyright &y& Elsevier]
