Glass Ball as Bullet Solubility System: Anthracene with Benzene
Components:
   (1) Benzene; C6H6; [71-43-2]  NIST Chemistry WebBook for detail
   (2) Anthracene; C14H10; [120-12-7]  NIST Chemistry WebBook for detail
Evaluator:
   W.E. Acree, Jr. Department of Chemistry University of North Texas Denton, Texas 76203-5068 (USA) June, 1994.

 Critical Evaluation:
   Anthracene solubilities in benzene were retrieved from papers by Coon et al. (1), Somayajulu and Palit (2), McLaughlin and Zainal (3), Smutek et al. (4), Acree and Rytting (5) and Mahieu (6). The first three studies report observed values at several temperatures, Smutek et al. report values at 293 and 298 K, and the latter two papers report the mole fraction solubility at 298 K. There is not a prior reason to exclude any of the six studies from the critical evaluation.
          Regressional analysis of the experimental data as Ln x1 versus 1/T yielded the following mathematical relationship:
          Ln x1 = -3200.1 (1/T) + 5.7899 (r = 0.9987)
for variation of anthracene solubility with absolute temperature (see graph below). Back-calculated solubility at 298 K is x1 = 0.00713, and differs by less then 4 % from experimental values of x1 = 0.00711 (4), x1 = 0.007418 (5) and x1 = 0.00740 (6).
