Published solubility data for N-ethylcarbazole dissolved in binary (ethanol+petroleum ether) solvent mixtures has been reanalyzed by using the combined nearly ideal binary solvent/Redlich-Kister (CNIBS/R-K) and Jouyban-Acree models. The CIBS/R-K model was found to describe the observed solubility data to within an overall absolute mean deviation of 1.7%. Slightly larger mean deviations of approximately 6.6% were noted for the Jouyban-Acree model. Mathematical expressions are derived for predicting the solubility N-ethylcarbazole dissolved in binary (ethanol+petroleum ether) solvent mixtures as a function of both temperature and binary solvent composition.
