Adsorption of Supercritical Carbon Dioxide on Silica

Langmuir, 2001
In this work, the adsorption isotherms of carbon dioxide on silica have been measured with a gravimetric method at nine different temperature values (from 312 up to 466 K) and at pressure levels up to 366 bar. The adopted technique allows for a direct evaluation of the density that is measured simultaneously to the adsorption load, thus avoiding ...

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 ...

Foaming of polypropylene with supercritical carbon dioxide

The Journal of Supercritical Fluids, 2007
This work is aimed at studying the foaming behavior of polypropylene (PP) with supercritical carbon dioxide (scCO2). The effects of saturation time, foaming temperature, saturation pressure and depressurization rate on the foam structure and volume expansion ratio were investigated.

Dyeing of Cotton in Supercritical Carbon Dioxide

Dyes and Pigments, 1998
Abstract The dyeing of cellulosic fibers with disperse and natural dyes was attempted using supercritical carbon dioxide (CO2SCF) as solvent system. The dye uptake was strongly increased if cotton was pretreated with polyethylene glycol (PEG), a known plasticizing agent of cellulose, while reasonable wet-washing and light fastness properties were ...

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.

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 ...
