Description

The vapor-liquid equilibria of solutions 0.0002 to 1.0 mole fraction methanol in carbon tetrachloride at 10, 20, 30, 40 and 50°C have been examined. The equilibrium vapor and liquid compositions and the total pressure above these solutions at the five temperatures are reported. The "pure" vapor pressure of methanol, [unable to transcribe] (a function calculated from the quotient Pa/Na of partial pressure of methanol Pa and mole fractions of methanol in the liquid Na), and the calculated values of the heat of vaporization of methanol both conclusively indicate that in solutions more dilute than 0.001 mole fraction methanol there still … continued below

Description

The vapor-liquid equilibria of solutions 0.0002 to 1.0 mole fraction methanol in carbon tetrachloride at 10, 20, 30, 40 and 50°C have been examined. The equilibrium vapor and liquid compositions and the total pressure above these solutions at the five temperatures are reported. The "pure" vapor pressure of methanol, [unable to transcribe] (a function calculated from the quotient Pa/Na of partial pressure of methanol Pa and mole fractions of methanol in the liquid Na), and the calculated values of the heat of vaporization of methanol both conclusively indicate that in solutions more dilute than 0.001 mole fraction methanol there still exists strong intermolecular attraction. This interaction is attributed to the existence of methanol dimers. A value of 7.6 to 11.2 kcal/mole is estimated for the dissociation of the dimer; this is the energy of the hydrogen bond if there is one hydrogen bond per dimer, and if there are two hydrogen bonds per dimer the energy of the bond is one-half this value.
