Standard uncertainty, u, is u(T) = 2 K. Relative standard uncertainties, ur are ur(p) = 0.1, ur(x1) = 0.01, ur(w3) = 0.001, and ur(w4) = 0.003. refers to the experimental mole fraction solubility. refers to the calculated solubility data using the Apelblat and λh model equations. RD represents the corresponding relative deviation. w3 is the mass fraction of acetone (3) in binary IPA (2) + acetone (3) mixture. w4 is the mass fraction of hexane (4) in ternary IPA (2) + acetone (3) + hexane (4) mixture.
