Solubility and Phase Behavior of CL20 in Supercritical Fluids
Abstract
The solubility of CL20 in supercritical carbon dioxide (CO2) was evaluated using the Peng-Robinson cubic equation of state. Thermodynamic properties of CL20 were required for this estimation. A comprehensive search of the literature revealed little data regarding the critical point of the compound. Also lacking were vapor pressure data for the compound. Critical properties as well as other required thermodynamic properties were estimated using a variety of available estimation techniques, including the group contribution methods of Lydersen and of Joback. The solubility of CL20 in supercritical CO2 was estimated using a Fortran program developed during the course of this project. Estimations spanned a reduced temperature range of 1.003 to 1.21 K and a reduced pressure range of 1.01 to 2.06 atm with respect to CO2. The Fortran program was validated using available literature data for the solubility of naphthalene and of biphenyl in supercritical CO2. The applicability of the estimation techniques employed for the critical properties for CL20 was established using these same techniques to estimate the critical properties of comparable compounds, including RDX and HMX. Solubility data for RDX in supercritical CO2 reported in the literature were also used to establish the validity of the estimation approach.
