Evaluation
Naphthalene solubilities in tetrachloromethane were retrieved from papers by Ward (1), McLaughlin and Zainal (2), Heric and Yeh (3), Acree et al. (4), Heric and Posey (5) and Chang (6). The first three studies report values at several temperatures, Acree et al. determined values at 303, 308 and 313 K, and both Heric and Posey and Chang measured the mole fraction solubility at the single temperature of 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 = - 2626.1 (1/T) + 7.4567 (r=0.9999) for variation of naphthalene solubility with absolute temperature (see graph below).
