Ebook: Solubilization of Oxymatrine in Water-in-Supercritical Carbon Dioxide Microemulsions

Статья "Солюбилизация оксиматрина в микроэмульсиях вода/сверхкритический диоксид углерода" журнала Journal of Chemical & Engineering Data, 2008 год, #53 (8), страницы 1705-1707The solubilization amount of oxymatrine in ammonium carboxylate perfluoropolyether (PFPE-NH4) water-in-supercritical carbon dioxide microemulsions with a water-to-surfactant molar ratio of (10.2, 14.8, and 21.0) was determined at temperatures of (308.15, 313.15, 318.15, 323.15, and 328.15) K and a density of 0.822 g ·mL-1 using a static apparatus with a sampling part. The determined solubilization amount of oxymatrine was 2 orders of magnitude higher than the solubility of oxymatrine in supercritical carbon dioxide and about 1/6 to 1/5 of the solubility of oxymatrine in bulk water. It was indicated that the solubilization amount of oxymatrine increased with an increase of the water-to-surfactant molar ratio and temperature in all experimental conditions.
