The total vapor pressures and the heats of mixing of the water‐tetrahydrofuran and water‐diethyl ether systems were measured at 25°. Density, index of refraction, and K ARL ‐F ISCHER ‐titration were used to determine concentrations for the total pressure measurements. The partial pressures, activity coefficients, excess free energies, entropy functions, and excess volumes were calculated.
