Components:
   (1) Benzene; C6H6; [71-43-2]  NIST Chemistry WebBook for detail
   (2) Biphenyl; C12H10; [92-52-4]  NIST Chemistry WebBook for detail

Original Measurements:
   Choi, P.B.; Williams, C.P.; Buehring, K.G.; McLaughlin, E., J. Chem. Eng. Data 1985, 30, 403-409.

Variables:
   Temperature = Temperature

T/K	Mole Fraction x1	Mole Fraction x2
307.95	0.4833	0.5167
313.85	0.5561	0.4439
316.85	0.5932	0.4068
323.65	0.6897	0.3103
328.95	0.7711	0.2289
333.15	0.8422	0.1578

Method/Apparatus/Procedure:
   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 visual noting  the temperature at which the last trace of solid solute appeared.

Source and Purity of Materials:
   (1) 99.6 %, Eastman Kodak Chemical Company, Rochester, New York, USA, was passed over activated alumina and recrystallized from toluene.
   (2) Gold Label, 99.9 %, Aldrich Chemical Company, was used as received.

Estimated Errors:
   Solubility: x₁: ± 0.0003.
   Temperature: T/K: precision ± 0.1.
