FLUID PHASE-EQUILIBRIUM STUDIES ON BINARY AND TERNARY MIXTURES OF CARBON-DIOXIDE WITH HEXADECANE, 1-DODECANOL, 1,8-OCTANEDIOL AND DOTRIACONTANE AT 393.2-K AND AT PRESSURES UP TO 100 MPA

Isothermal p(w) diagrams were determined for the binary systems CO2 + hexadecane, CO2 + 1-dodecanol, CO2 + 1,8-octanediol, CO2 + dotriacontane and hexadecane + 1,8-octanediol at 393.2 K and pressures from 10 to 100 MPa. In addition isothermal measurements were performed on the ternary systems CO2 + hexadecane + 1-dodecanol, CO2 + hexadecane + 1,8-octanediol, CO2 + 1-dodecanol + 1,8-octanediol and hexadecane + 1-dodecanol + 1,8-octanediol at the same conditions; an isobar of the system CO2 + hexadecane + 1-dodecanol at 25 MPa was also measured.
