Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 48 N° 10 (Mai 2009) . - pp. 4966–4974 Titre : Multicomponent inverse gas chromatography : determination of solubility and diffusivity in ternary polymer-solvent systems Type de document : texte imprimé Auteurs : J. Román Galdámez, Auteur ; Ronald P. Danner, Auteur Année de publication : 2009 Article en page(s) : pp. 4966–4974 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Inverse gas chromatography Ternary polymer-solvent-solvent system Solubility Diffusivity Résumé : The inverse gas chromatography technique was applied to measure solubility and diffusivity in a ternary polymer−solvent−solvent system. This method requires the comparison of the experimental elution profiles with theoretically predicted ones. A new simplified model was developed to describe ternary systems. In addition, a new experimental apparatus was constructed to monitor the independent composition profiles during a multicomponent experiment. The model was evaluated using experimental data for the system poly(vinyl acetate)−toluene−tetrahydrofuran at 80 and 100 °C. Solubility and diffusivity of the mixed solvents in poly(vinyl acetate) were collected at 80°.
