Experimental Data:   (Notes on the Nomenclature)
  

T/K	Mole Fraction x1	Mole Fraction x2
306.2	0.0502	0.9498
319.8	0.0910	0.9090
331.8	0.1515	0.8485
342.2	0.2435	0.7565

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 same temperature at which the last trace of solid solute disappeared.*

Source and Purity of Materials:
   (1) Purity not given, Gesellschaft fur Teerverwertung, was passed over an alumina column with benzene as eluant.
   (2) Purity, source and purification method was not specified.

Estimated Errors:

   Temperature: T/K: precision ± 0.1. x₁: ± 0.0003 (compiler).
