Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 48 N° 16 (Août 2009) . - pp. 7821–7827 Titre : High-pressure phase behavior for poly[dodecyl methacrylate] + supercritical solvents + cosolvents and carbon dioxide + dodecyl methacrylate mixture Type de document : texte imprimé Auteurs : Liu Shuang, Auteur ; Ha-Yeon Lee, Auteur ; Soon-Do Yoon, Auteur Année de publication : 2009 Article en page(s) : pp. 7821–7827 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Cloud-point curve Poly(dodecyl methacrylate) Dodecyl methacrylate Binary mixtures Ternary Résumé : Experimental cloud-point curves for poly(dodecyl methacrylate) [P(DDMA)] + dodecyl methacrylate (DDMA) or dimethyl ether (DME) in supercritical CO2 are reported for the binary and ternary mixtures up to 473 K and 248.0 MPa. The location of the P(DDMA) + CO2 cloud-point curve shifts to lower temperatures and pressures when DDMA or DME is used as a cosolvent. P(DDMA) does not dissolve in pure CO2 to the temperature of 493 K and the pressure of 260.0 MPa. High-pressure phase behavior data are presented for the CO2 + DDMA system at 313.2−393.2 K and up to ca. 25.2 MPa. The system exhibits type-I phase behavior with a continuous mixture-critical curve, and the system is adequately modeled with the Peng−Robinson equation of state. High-pressure phase behavior data are reported for P(DDMA) in supercritical propane, propylene, butane, and 1-butene. Cloud-point curves for the P(DDMA) in C4 hydrocarbons are at lower temperatures than the P(DDMA) + C3 hydrocarbons curves at fixed pressures.
