Solubility of 3,3′-Diindolylmethane in mono-Solvents at various temperatures: Re-analysis of the experimental data and thermodynamic calculations

This communication reports some comments on the published results and illutrates the applicability of a new multi-parameter model to represent the solubility of 3,3′-diindolylmethane (DIM) in various mono-solvents at different temperatures. The accuracy of the model was assessed by computing the relative average deviation (RAD) where an acceptable error range was observed for correlating the data. Moreover, the Hildebrand and Hansen solubility parameters of this organic compound were also calculated and reported, as well as the apparent thermodynamic quantities of dissolution and mixing of DIM in these organic solvents as estimated by means of the van’t Hoff and Gibbs equations.
