Synthesis of Fluoropolymers in Supercritical Carbon Dioxide

Science, 1992
Fluoropolymers are used in many technologically demanding applications because of their balance of high-performance properties. A significant impediment to the synthesis of variants of commercially available amorphous fluoropolymers is their general insolubility in most solvents except chlorofluorocarbons (CFCs).

Solubility of Cannabinol in Supercritical Carbon Dioxide

Journal of Chemical & Engineering Data, 2010
Cannabinol (CBN) is a decomposition product of the cannabinoid (-)-¿9-tetrahydrocannabinol (¿9-THC), the main active compound of cannabis. The solubility of CBN in supercritical carbon dioxide was determined at (314, 327, and 334) K and in the pressure range from (13.0 to 20.2) MPa by using an analytical method with a quasi-flow apparatus.

Olefin Metathesis in Supercritical Carbon Dioxide

Journal of the American Chemical Society, 2001
Liquid or supercritical carbon dioxide (scCO(2)) is a versatile reaction medium for ring-opening metathesis polymerization (ROMP) and ring-closing olefin metathesis (RCM) reactions using well-defined metal catalysts. The molybdenum alkylidene complex 1 and ruthenium carbenes 2 and 3 bearing PCy(3) or N-heterocyclic carbene ligands, respectively, can be

Dispersion Polymerizations in Supercritical Carbon Dioxide

Science, 1994
Conventional heterogeneous dispersion polymerizations of unsaturated monomers are performed in either aqueous or organic dispersing media with the addition of interfacially active agents to stabilize the colloidal dispersion that forms. Successful stabilization of the polymer colloid during polymerization results in the formation of high ...

Precipitation of Proteins in Supercritical Carbon Dioxide

Journal of Pharmaceutical Sciences, 1996
Supercritical CO2 was used as an antisolvent to form protein particles that exhibited minimal loss of activity upon reconstitution. Organic protein solutions were sprayed under a variety of operating conditions into the supercritical fluid, causing precipitation of dry, microparticulate (1-5 microns) protein powders.

Pharmaceutical Processing with Supercritical Carbon Dioxide

Journal of Pharmaceutical Sciences, 1997
Replacement of traditional solvents with "environmentally benign" carbon dioxide is receiving increased attention in pharmaceutical processing. Among the reported applications, particle formation with dense carbon dioxide and the "clean" synthesis of drug compounds using carbon dioxide as a reaction medium hold immense potential for large-scale ...

Dissolution of uranium dioxide in supercritical fluid carbon dioxide

Chemical Communications, 2001
Uranium dioxide can be dissolved in supercritical CO2 with a CO2-philic TBP-HNO3 complexant to form a highly soluble UO2(NO3)(2).2TBP complex; this new method of dissolving UO2 that requires no water or organic solvent may have important applications for reprocessing of spent nuclear fuels and for treatment of nuclear wastes.
