Abstract:Namen diplomske naloge je izmeriti ravnotežne topnosti organskih topil v plinih pri nizkih tlakih. Za sistema ogljikov dioksid-metil acetat ter propan-propil acetat smo raziskali fazno obnašanje, kar pomeni vpliv tlaka in temperature na mešljivost, topnost in morebitno inverzijo faz v sistemu. Topnosti smo določili s statično-analitično metodo pri temperaturah 40°C, 60°C in 80°C v visokotlačni optični celici v območju tlakov od 10 bar do 60 bar. Nato smo z ustreznimi računalniškimi orodji izračunali topnost ter določili vpliv temperature in tlaka na topnost. Opazimo, da lahko že z majhnimi spremembami tlaka in temperature povzročimo velike spremembe gostote fluida ter s tem njegove sposobnosti raztapljanja oz. različne topnosti snovi v super kritičnem topilu. Rezultati so podani v obliki tabel in grafov, ki prikazujejo topnost v masnih deležih kot funkcijo tlaka, temperature oz. gostote plina.

Title:SOLUBILITY OF ORGANIC SOLVENTS IN GASES AT LOW PRESSURES
Abstract:The aim of this thesis is to measure equilibrium solubility of organic solvents in the gases at low pressures . For systems carbon dioxide - methyl acetate and propane - propyl acetate phase behavior was studied, which means the influence of pressure and temperature on miscibility, solubility and possible inversion of phases. Solubilities were determined by a static - analytical method, at temperatures of 40°C, 60°C and 80°C in a high pressure optical cell in the range of pressures from 10 bar up to 60 bar. Then, solubility was calculated using appropriate computer software and effect of temperature and pressure on solubility was investigated. It is evident that even small changes in presssure and temperature reflect in large changes of fluid density and its solvent power. Results are shown in tables and graphs where solubility is presented as a function of pressure, temperature or gas density.
Keywords:binary systems, methyl acetate, propyl acetate, propane, carbon dioxide, solubility
