A new apparatus for the dynamic determination of solid compounds solubility in supercritical carbon dioxide Solubility determination of triphenylmethane

摘要

An apparatus for the determination of solid compounds solubility in supercritical carbon dioxide is presented.It is based on the dynamic saturation method of the supercritical fluid.The concept of the apparatus is introduced.First measurements were made with naphthalene in order to prove the efficiency of the apparatus.The results of experiments with triphenylmethane are presented at three different temperatures.The measured solubilities were correlated using the model of Adachi and Lu.
