Experimental Setup for Measuring the Solubility of Substances in Supercritical Carbon Dioxide by the Dynamic Method
Abstract
An experimental setup was created to measure the solubility of substances in supercritical carbon dioxide by a dynamic method, including the possibility of adding a cosolvent to the main solvent: CO2. A new technique has been developed for determining the mass amount of supercritical carbon dioxide that has passed during the experiment, which is important in determining solubility. Experimental data on the solubility of diphenyl in supercritical carbon dioxide are obtained, which are in good agreement with the literature data, at various state parameters: temperature and pressure. The experimental setup will make it possible to obtain new experimental data in the future on the solubility of a wide range of substances in supercritical carbon dioxide as well as in supercritical carbon dioxide with various organic cosolvents.
