“…Previous research on the purification of essential oils using the liquid–liquid extraction method has been widely applied using appropriate solvent selection such as organic solvents mixed with water alcohol, ionic liquids, and deep eutectic solvents. − Zhang, Sucipto, , Koshima, and Gonçalves have carried out experiments in separating essential oils using mixed solvents of water and alcohol at different temperatures and obtained the solubility of each solvent in separating essential oils. On the other hand, Domańska, Li, and Matsuda use ionic liquid solvents in purifying essential oils using liquid–liquid extraction, but ionic liquids have high viscosity, and the toxicity and price of ionic liquids are higher when compared to organic solvents.…”

Liquid−liquid equilibrium data for ternary systems of geraniol + ethanol + water and citronellol + ethanol + water were obtained experimentally under atmospheric pressure and at temperatures of 303.15 and 323.15 K. The experiment was carried out using a jacketed equilibrium cell as a reference for citronella oil derivative component purification by the solvent extraction method. The experiment was held for 4 h stirring and 20 h settling before the organic and aqueous sample phases were taken to be analyzed. Gas chromatography was used to analyze the equilibrium samples of the organic and aqueous phase compositions. The experimental data were found to be thermodynamically consistent with the Othmer−Tobias and Bachman−Brown correlations. The data were well-correlated by NRTL and UNIQUAC models with rmsd ranging from 0.0086 to 0.0164 and following the type 1 classification by Treybal.
