Chapter 19 - Organometallic compounds solubility in supercritical carbon dioxide (SCCO2): Measurement techniques, variables affecting solubility, recent developments, and thermodynamic modeling

Abstract

Organometallic compounds can widely be applied as reagents in the production and processing of new and advanced inorganic substances, as catalysts or precursors in preparation of different chemicals, and as chemotherapy drugs or in the design of novel medical therapeutics. Solubility data of the organometallic compounds in the supercritical fluids (SCFs) are required for establishing optimum operating conditions and designing of SCF processes. In addition, better knowledge on the dissolution phenomenon can be provided by mathematical modeling of organometallic compounds solubility in SCFs. Furthermore, solubility modeling can provide an approach to estimate solubility at different operating conditions with a minimum of experimental data. All this can enhance the development and progress rate of an SCF process. In this chapter, types of organometallic compounds, their solubility in supercritical carbon dioxide (SCCO2), measurement techniques, variables affecting solubility, recent developments, and thermodynamic modeling (model based on regular solution theory, empirical models, and equations of states (EOSs)) are discussed.
