Method/Apparatus/Procedure:

The method of Treybal [1] was used. For determining the phase distribution data, known mixtures of ternary constituents comprising of (1), (2) and (3) well within the heterogeneous region were placed in a constant temperature bath after vigorous agitation and allowed to separate into two phases after attaining equilibrium. The two phases were separated and weighed. A weighed quantity of each phase was taken in a distilling flask, and water bath. Traces of (1) and (2) remaining were removed under vacuum by drying the esters on a water bath to constant weight under a stream of carbon dioxide. Total weight of the esters thus obtained was checked against the weight of ester taken originally in the mixture.

Source and Purity of Materials:

1. Fluka AG; distilled; BP = 100.5-101.5°C, $n_{D}^{30}$, = 1.3770, $d_{4}^{30}$ = 1.1237.
2. BDH Ltd.; laboratory reagent-grade; distilled; BP = 67-70°C, $n_{D}^{30}$, = 1.3761, $d_{4}^{30}$ = 0.6782.
3. Prepared by methylation of castor oil; using $\ce{HCl}$ as catalyst; dried and distilled.

Estimated Errors:

Ambient temperature: control to ±0.1 K.
