Owing to extend the applicability of analytical solution of groups (ASOG) to the systems composed of the hydrofluoroethers, hydrofluorocarbons, and the solvents, its group pair parameters of CF2/CH2, CF2/O(HFE), CF2/O(ether), and CF2/OH have been newly determined using 10 binary vapor-liquid equilibrium data at 101.3 kPa. The group pair parameters relating CHF2, CH2F, and CBF groups were assumed to equate to those containing CF2 group. The vapor-liquid equilibria at 101.3 kPa were predicted with good accuracy using the determined parameters for 11 binary systems constituted by the hydrofluoroethers and alcohols.
