The vapor pressures of fluoroethers(1,1,2,3,3,3-hexafluoropropyl 2,2,2-trifluoroethyl ether and nonafluorobutyl methyl ether) were measured at 283.15 - 323.15 K using a gas stripping method. The infinite dilution activity coefficients of fluoroethers in hexadecane or water were measured at 283.15 - 313.15 K using a gas stripping method. The experimental results were correlated by the modified ASOG previously proposed.
