Conditions:
Room Temp: Temperature $\pu{K}$
Compiler:
Methodology:
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.
Sample Information:
- Purity and chemical source were not specified in paper.
- Purity and chemical source were not specified in paper.
Measurement Errors:
Ambient temperature: T/K: precision ±0.2 (compiler). x1: ±0.002 (compiler).
System Components:
- Naphthalene, $\ce{ C10H8 }$; [91-20-3] NIST WebBook
- 1,3,5-Trinitrobenzene, $\ce{ C6H6N3O6 }$; [99-35-4] NIST WebBook
