High Pressure Phase Behavior for the Poly[tridecyl methacrylate] and Tridecyl Methacrylate in Supercritical Carbon Dioxide and Dimethyl Ether |
| 초록 |
Experimental cloud-point curves for poly(tridecyl methacrylate) [P(TDMA)] + tridecyl methacrylate (TDMA) or dimethyl ether (DME) in supercritical CO2 show the binary and ternary mixtures up to 200 oC and 2,600 bar. The location of the P(TDMA) + CO2 cloud-point curve shifts to lower temperatures and pressures when TDMA or DME is used as a cosolvent. P(TDMA) does not dissolve in pure CO2 to the temperature of 220 ℃ and the pressure of 2,800 bar. High pressures phase behavior data is presented for the CO2 + TDMA system at 40 ~ 120 ℃ and up to ca. 255 bar. The system exhibit type-I phase behavior with a continuous mixture-critical curve and the system is adequately modeled with the Peng-Robinson equation of state. |
