^aStandard uncertainties u are u(T) = 0.02 K, u(p) = 0.45 kPa; Relative standard uncertainty u_r is u_r (x) = 0.045. Solvent mixtures were prepared by mixing different masses of the solvents with relative standard uncertainty u_r(w) = 0.0002. w represents the mass fraction of methanol in mixed solvents of methanol (w) + water (1 − w).
