Conditions:
Room Temp: 300.1 - 342.3 $\pu{K}$
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:
- C.P. grade, Eastman Chemicals, was recrystallized from alcohol to give a MP = 69.1°C.
- Purity and chemical source were not specified, was purified by distillation.
Measurement Errors:
Ambient temperature: T/K: precision ±0.1.
Mole fraction - Liquid (1): x1: ±0.001.
System Components:
- Biphenyl, $\ce{ C12H10 }$; [92-52-4] NIST WebBook
- 1,4-Dichlorobenzene, $\ce{ C6H4Cl2 }$; [106-46-7] NIST WebBook
