Notes:
Continuous solid solutions were found in the chrysene - benz[a]anthracene system. T
in
refers to the temperature at which crystallization begins; T
fin
is the temperature at which crystallization of the solid solution concludes.
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.
