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

Essential oils have been used in diverse areas such as packaging, agriculture and cosmetics, for their antimicrobial and pesticide activity. The organic volatile compounds of the essential oils are involved in its activity. Controlling their release helps to prolong their functionality. In this study, a functionalized calcium carbonate porous coating was employed to control the release of thyme and rosemary oil in a confined space. The release rate was evaluated at 7 °C and 23 °C, gravimetrically. It was shown that the capillary effect of the porous coating slowed down the release of the volatiles into the headspace compared to the bulk essential oil. A linear drive force model was used to fit the obtained data from both essential oils. The model showed that rosemary reached the asymptotic mass loss equilibrium faster than thyme. This result can be explained by the diverse composition and concentration of monoterpenoids between the two essential oils. Temperature and degree of loading also played important roles in the desorption of the essential oils. It was observed that at high degrees of loading and temperatures the desorption of essential oils was higher. The above-described technology could be used for applications related to food preservation, pest control among others.

“…Because of the high boiling points and high viscosities of the mixture of β-caryophyllene, dipentene, and α-pinene, a modified Ellis vapor–liquid equilibrium still as shown in Figure was used to obtain the VLE data of the binary and ternary systems. The pressure was regulated using a pressure control system, which comprises of a vacuum pump, a WT3000 intelligent absolute pressure transmitter (Shanghai Welltech Automation Co., Ltd.) with an accuracy of 0.001 kPa, and a U-shaped mercury manometer with an accuracy of 0.5 mmHg, giving an uncertainty of 0.3 kPa.…”

The experimental vapor–liquid equilibrium (VLE) data for a ternary system of β-caryophyllene + dipentene + α-pinene and two binary systems composed of β-caryophyllene (1) + dipentene (2) and dipentene (2) + α-pinene (3) were measured using a modified Ellis still in the temperature range from 428.4 to 529.1 K at 100.7 kPa. The thermodynamic consistency test of the VLE data was carried out using the van Ness test and the McDermott–Ellis method. The binary VLE data were correlated using the Margules, Nonrandom Two-Liquid (NRTL), Wilson, and Universal Quasi Chemical (UNIQUAC) activity coefficient models. The mean absolute deviation values of vapor-phase mole fraction and temperature are 0.0103 and 1.11 K for the β-caryophyllene (1) + dipentene (2) system and 0.0025 and 0.17 K for the dipentene (2) + α-pinene (3) system, respectively. The Wilson model parameters obtained from the binary systems were used to predict the ternary VLE data. By comparing the experimental values for the ternary system with the values calculated using the Wilson model, the mean absolute deviation value of the equilibrium temperature was determined to be 0.49 K; the absolute deviation values of the vapor-phase composition of β-caryophyllene and dipentene were determined to be less than 0.0078 and 0.0062, respectively.
