= 0.582 and T/K = 337.7.
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.
