Measurement and correlation of vapor–liquid equilibrium data for binary systems composed of camphene, (+)-3-carene, (-)-β-caryophyllene, p-cymene, and α-pinene at 101.33 kPa

Measurement and Prediction of Isothermal Vapor–Liquid Equilibrium and Thermodynamic Properties of a Turpentine + Rosin System Using the COSMO-RS Model

“…Moreover, comparing the two temperatures, it was found that the higher the temperature was, the faster the mole fraction of each component increased or decreased. The isobaric data for α-pinene (1) + β-pinene (3), 14 α-pinene (1) + p- cymene (4), 15 α-pinene (1) + longifolene (6), 16 and α-pinene (1) + camphene (2) 17 have already been reported. However, the pressure and temperature range measured in this work were beyond that available in the literature.…”

“…In their work, the activity coefficients of each component in each binary system were derived, and the excess Gibbs energy and excess enthalpy were obtained. Wu et al 17 reported the isobaric VLE data of binary systems with camphene, (+)-3-carene, (−)-β-caryophyllene, p -cymene, and α-pinene at 101.33 kPa. They found calculated values by NRTL, Wilson, and UNIQUAC models that were in good agreement with the experimental VLE data.…”

Vapor–Liquid Equilibria for Binary and Ternary Systems with β-Caryophyllene, Dipentene, and α-Pinene at 100.7 kPa

“…The uncertainties of temperature and pressure are 0.4 K and 0.3 kPa, respectively. 10 The expanded uncertainty for chromatographic analysis includes the five aforementioned elements, which are described by eq 4 19…”

“…The VLE data for the ternary β-caryophyllene (1) + dipentene (2) + α-pinene (3) mixture were estimated using the Wilson model with the binary interaction parameters obtained from the regression of the binary data as stated above and the binary data of β-caryophyllene (1) + α-pinene (3). 29 The comparison of the experimental and calculated ternary VLE data is shown in Figure 9. The mean absolute deviations and maximum absolute deviations of temperature (T), vapor-phase mole fraction (y 1 ), and vapor-phase mole fraction (y 2 ) are presented in Table 8.…”

“…Although heavy terpene components are widely used in fine chemical and pharmaceutical synthesis and flavor and fragrance industries, there are few studies on the vapor−liquid equilibrium (VLE) data of terpenes because of their high boiling points and high viscosities. Wu et.al 10 obtained vapor−liquid equilibrium data for binary systems composed of camphene, (+)-3-carene, (−)-β-caryophyllene, p-cymene, and α-pinene at 101.333 kPa. The vapor−liquid equilibrium data for the binary and ternary systems composed of (−)-β-caryophyllene, p-cymene, and 3carene at 101.333 kPa were determined by Yao et al 11 Furthermore, Kuswandi et.al 12 (2) + water (3) system at the temperatures 303.15, 313.15, and 323.15 K. In this paper, experimental VLE data for the binary systems βcaryophyllene + dipentene and dipentene + α-pinene as well as the ternary system β-caryophyllene + dipentene + α-pinene were obtained using a modified Ellis still at 100.7 kPa.…”
