APPLICATION OF THE MOBILE ORDER THERMODYNAMICS TO PREDICT THE SOLUBILITY OF SOLID HYDROCARBONS IN PURE SOLVENTS AND NONPOLAR BINARY SOLVENTSYSTEMS

This work extends the application of the thermodynamics of mobile orde r from the solubility prediction in single solvents to that in binary solvent blends without additional new parameters. Predicted solubiliti es are compared to the experimental values for solid n-octadedane, n-n onadecane and naphthalene in various non-polar, polar and hydrogen-bon ded pure solvents as well as in 22 two-component solvent systems invol ving only non-specific interactions. Absolute average deviations betwe en predicted and experimental results do not exceed 10 % in single sol vents and 5 % in binary mixtures. The solubility profiles versus solve nt composition show that the solubilities are additive in mixtures of solvents whose interaction characteristics are very similar.
