Solubilidad
Mezclas de {1,4-dioxano + agua}
Resume: Se informó la solubilidad en equilibrio del triclocarbán en mezclas de {1,4-dioxano (1) + agua (2)} a 293,15 K a 313,15 K. La solubilidad de la fracción molar aumenta continuamente de agua pura a 1,4-dioxano puro a todas las temperaturas. El comportamiento de solubilidad se correlacionó adecuadamente por medio de una serie de modelos de cosolvencia, incluido el modelo Jouyban-Acree. Sobre la base de las ecuaciones de Gibbs y van't Hoff, se calcularon las respectivas cantidades termodinámicas de disolución. Se observa un análisis de compensación de entalpía-entropía no lineal que indica un mecanismo de disolución diferente con la variación en la composición de las mezclas.
Abstract: The equilibrium solubility of triclocarban in {1,4-dioxane (1) + water (2)} mixtures at 293.15 K to 313.15 K was reported. Mole fraction solubility increases continuously from neat water to neat 1,4-dioxane at all temperatures. Solubility behavior was adequately correlated by means of a number of cosolvency models including the Jouyban-Acree model. Based on the Gibbs and van't Hoff equations the respective apparent thermodynamic quantities of dissolution were calculated. Non-linear enthalpy-entropy compensation analysis is observed indicating different dissolution mechanism with the variation in mixtures composition.
