Ternary and quaternary (liquid+liquid) equilibria for (water+ethanol+α-pinene, +β-pinene, or +limonene) and (water+ethanol+α-pinene+limonene) at the temperature 298.15K

(Ternary liquid+liquid) equilibria for (water+acetone+α-pinene, or β-pinene, or limonene) mixtures

“…So the phase equilibria data for ternary mixtures containing a-pinene, b-pinene, and limonene with water and acetone is necessary in the extraction process design and development. For example, the (liquid + liquid) equilibria of ternary mixtures containing terpene with alcohol had been investigated in the recent years [1][2][3][4][5]. In this work, the (liquid + liquid) equilibria for the ternary (water + acetone + a-pinene) mixtures at T = (288.15, 298.15, and 308.15) K and the ternary (water + acetone + b-pinene, or limonene) mixture at T = 298.15 K have been studied.…”

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

“…LLE has also been determined by Arce [11,12]. On the other hand, Li and Tamura studied ternary and quaternary LLE for {water + ethanol + a-pinene, + bpinene (or + limonene)} and (water + ethanol + a-pinene + limonene) at T = 298.15 K [13]. However, as far as we know, there is only one report on LLE data at T = 298.15 K for the ternary system studied here [7], but no measurements were performed at other temperatures.…”

Liquid-Liquid Equilibrium for System Composed of α-Pinene, α-Terpineol and Water

“…It is expected that the RMSD can represent the goodness of fit. In the UNIQUAC model, the values of volume and surface area parameter of pure component r i and q i , for water and α-pinene have been taken from literature [3]. The volume and surface area of the α-terpineol was estimated from the Bondi's method [12].…”

“…LLE information for α-pinene + Δ3 carene + polar compound (acetonitrile, nitromethane, and dimethylformamide) systems has been studied [2]. Hengde Li studied the ternary LLE for water + ethanol + α-pinene, + β-pinene, or + limonene and quaternary LLE for water + ethanol + α-pinene + limonene systems at the temperature of 298.15K [3]. The authors also report data for ternary LLE for water + terpene + 1-propanol or 1-butanol systems at the same temperature [4].…”
