(Liquid+liquid) equilibria of (water+linalool+limonene) ternary system at T=(298.15, 308.15, and 318.15)K

Fractionation of lemon essential oil by solvent extraction: Phase equilibrium for model systems at T=298.2K

“…The behaviour of the distribution coefficients of citral, an oxygenated compound, and the terpenic hydrocarbons (limonene, c-terpinene, and b-pinene) qualitatively agrees with results previously reported by Chiyoda et al [6], Arce et al [19,28] and Gramajo de Doz et al [20]. In these studies, using water or an (ethanol + water) mixture as a solvent, the authors obtained the highest reported partitioning of the oxygenated terpene linalool from the hydrocarbon limonene.…”

“…Previous studies on optimising the process of deterpenation by liquid extraction have tested many different types of solvents, including ionic liquids [14][15][16]; glycols [17,18]; water [19,20]; aminoethanol [21]; acetonitrile, nitromethane and dimethylformamide [22]; and short chain alcohols, such as methanol [23,24], ethanol [6,19,[25][26][27][28], propanol, and butanol [29].…”

Extraction of aroma compounds of fruit juices by air stripping using a bubble column operating with antifoam and its effect on juice properties

“…Similar problem was observed by Gramajo de Doz et al (2008). We added 130 lL/L of limonene to the solution, but we could quantify just 1.64 ± 0.96 lL/L.…”

Improved concentration of citrus essential oil by solvent extraction with acetate ionic liquids

“…As a consequence, deterpenation by distillation techniques needs to be combined with solvent extraction, or there is risk of loss of quality of the oil due to polymerisation and resinification reactions [7]. Regarding extraction with solvents, a few extractants that have been explored at a research level are the following: ethanol, methanol, and their aqueous solutions; and also ethyl acetate and acetone; among others [8][9][10]. Countercurrent liquid-liquid extraction is also a possibility with pentane being used as a second solvent along with diluted methanol or ethanol.…”
