HIGH PRESSURE PHASE EQUILIBRIUM OF THE BINARY SYSTEM TWEEN 80 AND CARBON DIOXIDENovak, Natalija (Avtor) Škerget, Mojca (Mentor) Knez, Željko (Komentor) supercritical fluidsphase equilibriumcarbon dioxideTween 80In the frame of the diploma thesis we researched the phase equilibrium of the binary system Tween 80 and CO2. Equilibrium compositions of the system have been determined with a static analytical method at temperature 40, 60 and 80 °C and pressures up to 300 bar. The obtained data was plotted in isothermal diagrams where mass percentage is presented as a function of pressure. In this work also the viscosity of Tween 80 was determined in the temperature range between 20 and 80°C and shear rates up to 180 s-1. The measurements were obtained by using coaxial cylinder and compared with available literature data. [N. Novak]20142014-04-08 11:11:17Diplomsko delo44055sl
