Resume: La solubilidad del triclocarbán (TCC) se determinó en mezclas de codisolvente de {etilenglicol (EG) + agua} a 7 temperaturas (288,15–318,15 K). La solubilidad de TCC aumenta al aumentar la temperatura y la polaridad del sistema de codisolvente disminuye al aumentar la concentración de EG. En ese caso, el TCC alcanza su mínima solubilidad en agua pura a 288.15 K y su máxima solubilidad en EG a 318 K. Las funciones termodinámicas se calcularon mediante la ecuación de van Hoff, y se determinó que el proceso es endotérmico y, según la entropía entalpía El análisis de compensación está impulsado por la entropía en mezclas ricas en agua y por la entalpía en mezclas intermedias y ricas en EG. De acuerdo con las funciones de transferencia, TCC tiende a transferir de medios polares a menos polares. En cuanto al análisis de solvatación preferencial, realizado mediante el modelo IKBI,
Abstract: The solubility of triclocarban (TCC) was determined in {ethylene glycol (EG) + water} cosolvent mixtures at 7 temperatures (288.15–318.15 K). The solubility of TCC increases with increasing temperature and the polarity of the cosolvent system decreases with increasing EG concentration. In that case, TCC reaches its minimum solubility in pure water at 288.15 K and maximum solubility in EG at 318 K. The thermodynamic functions were calculated using the van Hoff equation, and it was determined that the process is endothermic and, according to entropy enthalpy compensation analysis, is driven by entropy in water-rich mixtures, and by enthalpy in intermediate and EG-rich mixtures. According to transfer functions, TCC tends to transfer from polar to less polar media. Regarding preferential solvation analysis, carried out using the IKBI model, TCC is preferentially solvated by water in water-rich mixtures and by EG in intermediate and EG-rich mixtures.
