20.500.12556/DKUM-44055 HIGH PRESSURE PHASE EQUILIBRIUM OF THE BINARY SYSTEM TWEEN 80 AND CARBON DIOXIDE VISOKOTLAČNA FAZNA RAVNOTEŽJA BINARNEGA SISTEMA TWEEN 80 IN OGLJIKOVEGA DIOKSIDA In 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. Diplomsko delo obsega študijo faznih ravnotežij binarnega sistema Tween 80 in CO2. Ravnotežne sestave sistema smo določili s statično analitično metodo pri temperaturah 40, 60 in 80 °C ter tlakih do 300 bar. Pridobljene rezultate smo prikazali v izotermnih diagramih, ki prikazujejo odvisnost masnega deleža od tlaka. Z rotacijskim viskozimetrom (Haake RS75)smo določili viskoznost Tweena 80 v temperaturnem območju med 20 in 80 °C ter pri strižnih napetostih do 180 s-1. Meritve smo primerjali z obstoječimi podatki iz literature. supercritical fluids phase equilibrium carbon dioxide Tween 80 superkritični fluidi fazna ravnotežja ogljikov dioksid Tween 80 true true false [N.
