Method/Apparatus/Procedure:
The titration method, as described in Ref. 1, was used. The titrant, from a weighed pipette, was added to the weighed binary mixture of known composition and the mixture was kept in a thermostated bath. To confirm that the end-point was reached the mixture was shaken automatically for at least 15 min and then reexamined. The plot of refractive index against composition was then used to find compositions of equilibrium phases. The refractive indexes were determined at the temperature of 30.0°C to eliminate an opalescene.
