Abstract:S statično analitično metodo smo izmerili ravnotežne topnosti etilmaltola v ogljikovem dioksidu in propanu pri temperaturah 40, 60 in 80°C v območju tlakov od 30 do 250 bar. Analizo vzorcev smo opravili z UV-VIS spektrofotometrom z metodo umeritvenih krivulj. Rezultate smo podali v obliki tabel in grafov v odvisnosti molskega deleža od tlaka in temperature ter odvisnosti masnega deleža od gostote in temperature.

Title:SOLUBILITY OF ETHYLMALTOL IN GASES AT HIGH PRESSURES
Abstract:The equilibrum solubilities of ethylmaltol in carbon dioxide and propane were measured by a static-analytic method at temperatures 40, 60 and 80 °C and in the pressure range from 30 to 250 bar. Analyses of samples were performed with UV-VIS spectrophotometer by using calibration curves. Results are given in form of tabels and graphs, presenting the dependence of the mole fraction on the pressure and the temperature and the dependence of the mass fraction on the density ant the temperature.
Keywords:supercritical fluids, ethylmaltol, equilibrium solubility, propane, CO2
