Experimental cloud-point curves of binary and ternary mixtures for poly(butoxyethyl acrylate) [P(BEA)] in supercritical carbon dioxide, dimethyl ether (DME), propane, propylene, butane and 1-butene were measured at temperature range of (40 ~ 180)℃ and pressures up to 2243 bar. Cloud-point behavior of those systems were showed in changed of the pressure-temperature (P-T) when solvent content was changed. Also, experimental data of phase behaviors for BEA in supercritical carbon dioxide was performed at temperature range of (40 ~ 120)℃ and pressure range of 47 ~ 204 bar. The experimental results were modeled with the Peng-Robinson equationof state with two adjustable parameters. |
