Notes:
     Author reports eutectic point occurs at x1 = 0.348 and T/K = 333.7.

Method/Apparatus/Procedure:
   Phase diagram was determined using a thermal analysis method (described in detail in V.M. Kravchenko, J. Phys. Chem. U.S.S.R. 1939, 13, 133), supplemented by visual observations.

Source and Purity of Materials:
   (1) Purity and chemical source were not specified in paper, was recrystallized before use.
   (2) Purity and chemical source were not specified in paper, was recrystallized before use.

Estimated Errors:

   Temperature: T/K: precision ± 0.2. x1: ± 0.002 (compiler).
