Glass Ball as Bullet Solubility System: Anthracene with Methylbenzene

Components:
   (1) Methylbenzene; C7H8; [108-88-3]  NIST Chemistry WebBook for detail
   (2) Anthracene; C14H10; [120-12-7]  NIST Chemistry WebBook for detail

Original Measurements:
   Smutek, M.; Fris, M.; Fohl, J., Collection Czech. Chem. Commun. 1967, 32, 931-943.

Variables:
   Temperature = 293 K, 313 K and 333 K

t/°CMole Fraction x1Mole Fraction x2
20.00.006450.9935
40.00.01240.9876
60.00.02300.9770
Method/Apparatus/Procedure:
   Constant temperature bath, thermometer, and a precision balance. Excess solute and solvent placed in closed glass container and allowed to equilibrate for several hours at constant temperature. Aliquots of saturated solutions were transferred into tared containers and weighed.  Solubilities calculated from weight of solid residue that remained after solvent had evaporated.

Source and Purity of Materials:
   (1) 95 % initial purity, Urxovy Zavady, Czech., was recrystallized several times from pyridine and cyclohexane to give a final purity of 98.3 %.
   (2) 99 %, Commercial sample, source and purification method was not specified.

Estimated Errors:
   Solubility: x1: ± 3 % (relative error; compiler).
   Temperature: T/K: precision ± 0.05.
