Conditions:
Room Temp: 333.3 - 502.2 $\pu{K}$
Compiler:
Methodology:
Constant temperature bath and a precision thermometer. Mixtures of known concentrations sealed in glass ampoules and placed in constant temperature to equilibrate. Samples were rotated while bath temperature slowly increased. Solubility determined by noting the temperature at which the last trace of solid solute disappeared.
Sample Information:
- 99+%, Aldrich Chemical Company, Milwaukee, Wisconsin, USA, was used as received.
- 99+%, Aldrich Chemical Company, having isomer ratio of 60.6% cis and 39.4% trans, stored over molecular sieves.
Measurement Errors:
Ambient temperature: T/K: precision ±0.1.
Mole fraction - Liquid (1): x1: ±0.0003.
System Components:
- Carbazole, $\ce{ C12H9N }$; [86-74-8] NIST WebBook
- Decahydronaphthalene, $\ce{ C10H18 }$; [91-17-8] NIST WebBook
