Solubility assessment of castor ( Ricinus communis L) oil in supercritical CO 2 at different temperatures and pressures under dynamic conditions

Study of Solubility in Supercritical Fluids: Thermodynamic Concepts and Measurement Methods - A Review

“…As the main advantage of the analytic-flow method, the sampling in this method is faster and easier than the sampling in other methods, and it does not disturb the equilibrium state. This method was used by Shimoyama et al (2008) to investigate phase equilibria; it is applied by many other researchers (Suzuki et al, 1991;, Xing et al, 2003;Ferri et al, 2004;Ghaziaskar and Kaboudvand, 2008;Tang et al, 2011;Jin et al, 2012;Li et al, 2013;Danlami et al, 2015;and Wu et al, 2016) to examine solubility.…”

Effect of particle size on yield extract and antioxidant activity of peanut skin using modified supercritical carbon dioxide and soxhlet extraction

“…The extract was separated by a vacuum dry. The temperature of vacuum dry was set at 40 °C and pressure at 80 mBar to avoid degradation of the bioactive compound (Danlami, Zaini, Arsad, & Yunus, ).…”

Optimization of Supercritical Carbon Dioxide and Co-solvent Ethanol Extraction of Wasted Peanut Skin Using Response Surface Methodology

“…Increasing of pressure on the extraction process increases the density of carbon dioxide may affect of diffusivity of carbon dioxide to carry out of extract from solute [14]. This is similar funding with extraction of castor oil that increasing of pressure will increase the yield extracts [15]. It proofed that in the table 3 p-value of pressure X 1 is lower than p-value (0.05 > 0.0096) Fig.4.…”

“…At the highest temperature condition, temperature will degrade the bioactive compound inside of extract, but in the lowest temperature condition, effect of the solute vapour is not dominant that solvent is difficult to carried out the extract and its bioactive compound from solute. Effect of pressure is not dominant in this extraction process to enhance the antioxidant of extract because increasing of pressure will not degrade the bioactive compound [15,18]. It was proofed that p-value on the coefficient of model was higher than 0.05.…”
