Abstract One of the main steps in choosing the drug nanoparticle production processes by supercritical carbon dioxide (SC-CO2) is determining the solubility of the solid solute. For this purpose, the solubility of Ketoconazole (KTZ) in the SC-CO2, binary system, as well as in the SC-CO2-menthol (cosolvent), ternary system, was measured at 308–338 K and 12–30 MPa using the static analysis method. The KTZ solubility in the SC-CO2 ranged between 1.70×10− 6 and 8.02×10− 4, while drug solubility in the SC-CO2 with cosolvent varied from 2.7×10− 5 to 1.96×10− 4. This difference indicated the significant effect of menthol cosolvent on KTZ solubility in the SC-CO2. Moreover, KTZ solubilities in the two systems were correlated by several empirical and semiempirical models. Among them, Sodeifian et al., Bian et al., MST, and Bartle et al. models can more accurately correlate experimental data for the binary system than other used models. Also, the Sodeifian and Sajadian model well fitted the solubility data of the ternary system with AARD,%= 6.45, Radj= 0.995.

The studies of solubility of the paprika extract with a high concentration of carotenoids in carbon dioxide under the pressure of 20–50 MPa and at temperatures of 313.15–333.15 K were carried out using the static method. The highest solubility of paprika extract was achieved at the temperature of 333.15 K and under the pressure of 50 MPa. The obtained experimental data were correlated with five density-based models, applied for prediction of solubility in the supercritical carbon dioxide (the Chrastil, del Valle and Aguilera, Adachi and Lu, Sparks et al. and Bian et al. models). The accuracy of particular models with reference to measurement results was specified with the average absolute relative deviation (AARD) and coefficient of determination (R2). Results showed that solubility calculated based on the selected models was compliant with experimental data.

The solubility data of acetophenone in supercritical carbon dioxide (scCO2) were measured using a static method at several temperatures (313.15, 323.15, 333.15, and 343.15K) and pressures ranging from10 MPa to 28 MPa. The density based models (Chrastil and Del valle– Aguilera models) and the Peng-Robinson equation of state (PR-EOS) with quadratic and Stryjek-Vera combining rules were employed to correlate the experimental data. Good correlations between the calculated and experimental solubility data were obtained. The sum of squared errors (SSE) are 0.38 % and 0.37 % for Chrastil and Del Valle – Aguilera models, respectively; and 9.07 % for Peng-Robinson equation of state with quadratic combining rule and 4.00 % for Peng-Robinson equation of state with Stryjek-Vera combining rule.

Abstract Binary vapour-liquid equilibrium of thymoquinone and carbon dioxide at the isothermal conditions was carried out at temperature 323.15 K and pressures from 6 to 10 MPa. The experimental data were fitted to the Soave-Redlich-Kwong equation of state. Results could be used for selection of process parameters in separation of volatiles from raw oil or for evaluation of existing separation technologies.

Pithecellobium Jiringan (Jack) Prain (P.Jiringan) merupakan salah satu daripada sumber tumbuhtumbuhan yang mengandungi komponen antioksidan. Tujuan kajian ini dijalankan adalah untuk mengkaji kesan-kesan parameter kaedah penyarian bendalir lampau genting dengan menggunkan karbon dioksida sebagai pelarut (SC-CO2) ke atas hasil minyak dan untuk mengukur kebolehlarutan minyak P.Jiringan didalam (SC-CO2) dan mengkorelasi data kebolehlarutan minyak P.Jiringan dengan model Chrastil dan del Valle & Aguilera. Kajian ini telah dijalankan pada suhu antara 40oC sehingga 70oC dan pada tekanan antara 27.58 MPa sehingga 44.82 MPa. Tempoh pengekstrakan adalah 60 minit. Penemuan hasil kajian ini menunjukkan bahawa hasil minyak meningkat dengan peningkatan tekanan dan peningkatan suhu. Pada keadaan suhu malar, kebolehlarutan minyak meningkat dengan peningkatan kepadatan CO2. Analisis keputusan menunjukkan bahawa data keterlarutan minyak P.Jiringan telah berjaya dipadankan dengan model Chrastil. Di samping itu, SC-CO2 memberikan hasil minyak tertinggi berbanding dengan ASE dan proses pengekstrakan Soxhlet. Kata kunci: Kebolehlarutan; Model Chrastil; penyarian bendalir lampau genting; Pithecellobium Jiringan (Jack) Prain Pithecellobium Jiringan (Jack) Prain (P.Jiringan) is one of the medicinal plant sources that consist of antioxidant compounds. The aim of this study was to investigate the effects of supercritical carbon dioxide (SC-CO2) extraction parameters on oil yields and to measure the solubility of P.Jiringan oil in SC-CO2 and correlated the data with Chrastil and del Valle & Aguilera models. The experimental were conducted at temperatures ranging from 40oC to 70oC and pressure from 27.58 MPa to 44.82 MPa. The extraction duration was 60 minutes. The result shows that the oil yields increase as the pressure and temperature increase. The solubility of oil increased as the density of CO2 increased at constant temperature. An analysis of the results show that the solubility experimental data correlated with the Chrastil’s model was successfully matched. In addition, SC-CO2 give the highest oil yields compared to accelerated solvent extraction (ASE) and soxhlet extraction process.
