Abstract

Evtektična topila so novejša alternativa za ionske tekočine, saj imajo podobne lastnosti, vendar je njihova priprava enostavnejša in cenejša, zato se jih vse bolj poslužujejo predvsem v farmacevtski industriji. Njihova dobra lastnost pa je tudi ta, da so prijaznejša okolju. V tem diplomskem delu sem predstavila rezultate merjenja zmrzišč, gostote in viskoznosti petih evtektičnih topil L-mentola in oktanojske kisline. Evtektična topila L-mentol/oktanojska kislina sem pripravila v množinskih razmerjih 1:3, 1:2, 1:1, 2:1 in 3:1 ter jim izmerila gostoto in viskoznost pri temperaturah med 5 °C in 55 °C, v razmaku 10 °C. Poleg tega pa sem za primerjavo pri višjih temperaturah (35 °C, 45 °C, 55°C) izvedla meritve tudi za obe čisti komponenti. Rezultate sem predstavila v obliki tabel in grafov.

Secondary title: L-menthol and octanoic acid deep eutectic solvents
Secondary abstract: Deep eutectic solvents are a newer alternative to ionic liquids, as they have similar characteristics, but their preparation is less complex and cheaper, so they are increasingly used, especially in the pharmaceutical industry. Their good feature is also that they are more environmentally friendly. In this work, the results of measuring freezing points, density and viscosity of five eutectic solvents L-menthol and octanoic acid were presented. L-menthol/octanoic acid eutectic solvents were prepared with molar ratios of 1:3, 1:2, 1:1, 2:1 and 3:1 and their density and viscosity were measured at temperatures between 5 °C and 55 °C, with an interval of 10 °C. In addition, for comparison at higher temperatures (35 °C, 45 °C, 55 °C), I also performed measurements for both pure components. I presented the results in the form of tables and graphs.
