Abstract
Due to the increase in energy consumption at the global level, it is necessary to examine new possibilities of substitution of classical energy-intensive separation processes based on evaporation of more volatile components, separation processes based on liquid-liquid equilibria (LLE), i.e. extraction of components from liquid solutions. This procedure would also include the replacement of standard industrial solvents with environmentally harmful characteristics with new, green solvents. Diethyl adipate can be used for these purposes because it is relatively non-toxic, obtained from renewable sources and is biodegradable. In order to examine the possibilities of using green solvents, the possibilities of adequate replacement and process design, it is necessary to know thermodynamic data such as liquid-liquid equilibria data, the corresponding binodal curve and equilibrium lines. The liquid-liquid equilibria data of the ternary system water + ethanol + diethyl adipate will be determined experimentally at a temperature of 298.15 K and atmospheric pressure. Binodal curves will be determined using the synthetic blur method using both the titration technique and the equilibrium lines via the refractive index. The obtained experimental data will be used in determining the complete phase diagram of the mentioned system.
