Method/Apparatus/Procedure:
The points on the binodal curve were determined by the formation of a cloudy mixture on shaking after the addition of a known mass of one component to a mixture of known masses of the other two components. Precision weighing syringes were used as described in Ref. 1. Tie line compositions were determined by the refractive index method reported in Ref. 2 and a complementary method using the Karl Fischer titrations as reported in Ref. 3.
Source and Purity of Materials:
(1) Merck, AR grade; distilled, dried by refluxing with Mg and I
2
; purity better than 99.6 mole % by glc; d=0.786 88, n=1.3265.
(2) BDH; used as received; purity better than 99.6 mole % by glc.
(3) Source not specified.
Estimated Errors:
Solubility: Not reported.
Temperature: Estimated comp. 0.005 mole fraction on the binodal curve and 0.01 mole fraction for tie lines (estimated by the authors).
