WebTeoría de Flory-Huggins. El sistema agua-fenol no muestra comportamiento ideal porque las interacciones entre moléculas, agua-agua, fenol-fenol y agua-fenol, son importantes. De hecho, ya hemos dicho que para explicar su miscibilidad parcial debemos considerar que ΔHmix > 0. Además agua y fenol son moléculas de naturaleza y tamaño distinto. WebApr 22, 2024 · Values of Gibbs energy of mixing polysaccharides with water determined from the isotherms obtained are negative. The calculated Flory–Huggins parameters for polysaccharide solutions are almost the same and equal on average to 0.82.
