摘要：
The liquid-liquid equilibrium data and the specific heat capacities for the binary room temperature ionic solution {1-butanol + 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide} have been reported. The corresponding critical exponents beta and alpha were obtained and found to be well coincided with the 3D-Ising criticality. The critical complete scaling theory was applied to successfully describe the asymmetric behavior of the diameter of the coexistence curve with the consideration of the heat capacity related term. The large values of the reduced critical density, the reduced critical temperature and the critical amplitude related to the heat capacity were deduced, which indicated a solvophobic criticality of the studied system.
