Notes:
Compiler: Phase diagram indicates formation of a 1:1 fluorene - 1,3,5-trinitrobenzene molecular compound, with the two eutectic points at about x
1
= 0.252 and T/K = 373.2, and at x
1
= 0.700 and T/K = 358.8.
Method/Apparatus/Procedure:
Binary mixtures prepared by weight. While the experimental details were not given in the paper, compiler speculates (based upon quantity of material used) that the sample was sealed in a glass container, temperature slowly varied, and the phase diagram determined by visually noting the temperature at which the last/first crystal of solid disappeared/appeared.
Source and Purity of Materials:
(1) Purity and chemical source were not specified in paper.
(2) Purity and chemical source were not specified in paper.
Estimated Errors:
Temperature: T/K: precision ± 0.5 (compiler). x
1
: ± 0.002 (compiler).
