Method/Apparatus/Procedure:

The titration method was used. Binary mixtures of known volumes were titrated with the third component in glass-stoppered bottles until, after vigorously shaking, the mixture became turbid. The equilibrium phases were determined by titrating with water binary methanol-xylene mixtures. The xylene-rich phase was at the beginning the lower layer, but addition of water caused this phase to separate as the upper layer. To determine tie immersed in a thermostat bath, shaken, and after separation one component of each phase was analyzed by the Karl Fischer reagent and xylene, in the hydrocarbon-rich phase, was determined by extraction with water. The results were presented on a Gibbs triangle together with binodal curve.
