Supercritical carbon dioxide
The different techniques used for the determination of the solubility of compounds in supercritical carbon dioxide are described. A comparative study is made of the methods used in the measurement of the concentration of benzoic acid and caffeine in supercritical carbon dioxide. The difference in measurement techniques did not have much effect on the solubility data at lower pressures. However, at higher pressures, the solubility data obtained by different techniques began to deviate from each other.
Further, the method used by different researchers in generating the solubility data in supercritical carbon dioxide is also discussed. A number of data sheets have been prepared from these articles containing important information like the solubility, pressure range, temperature range, error in measurement of solubility. and also a brief explanation of the measurement technique. These data sheets form part of an IUPAC-NIST solubility data series project.
