Conditions:
Room Temp: Temperature $\pu{K}$
Compiler:
Methodology:
Differential scanning calorimeter.
Mixtures (1.5 - 2.0 mg) of known concentration were weighed into alumina pans, which were then crimped to preclude sample loss during the heating process. Solubilities determined by measuring melting points of binary mixtures using a PerkinElmer DSC-2 differential scanning calorimeter and scan rate of 5 k/min.
Sample Information:
- Gold Label, 99+%, Aldrich Chemical Company, Milwaukee, Wisconsin, USA, was used as received.
- 99%, Aldrich Chemical Company, was vacuum-distilled before use.
Measurement Errors:
Ambient temperature: T/K: precision ±0.3 (compiler). x1: ±0.0003 (compiler).
System Components:
- Naphthalene, $\ce{ C10H8 }$; [91-20-3] NIST WebBook
- Octadecane, $\ce{ C18H38 }$; [593-45-3] NIST WebBook
