Supercritical carbon dioxide (scCO2) could be one aspect of a significant and necessary movement towards green chemistry, being a potential replacement for volatile organic compounds (VOCs). Unfortunately, carbon dioxide has a notoriously poor solubilising power and is famously difficult to handle. This review examines attempts and breakthroughs in enhancing the physicochemical properties of ca...

We present our initial results on the use of supercritical carbon dioxide as both a reactant and as a reaction medium to photo-chemically produce carboxylic acids from polycyclic aromatic hydrocarbons via radical anion intermediates. In the present work, we have found that photolysis of anthracene in supercritical carbon dioxide produces up to 57% yield of 9,10-dihydroanthracene-9-carboxylic ac...

Supercritical fluids have a unique and valuable potential for the enhanced processing of many materials. This review describes research in the applications of supercritical fluids to polymer processing. The ability of supercritical carbon dioxide to swell and plasticize polymers is crucial to the impregnation, extraction, and modification of polymeric materials. This plasticization also reduces...

In the new global economy, consumption has become a central issue for many fields of industries. This project work studied on the effectiveness of pulse duration of supercritical carbon dioxide (SCCO2) in machining performance in terms of cutting temperature, cutting force and surface roughness in turning AISI 1045 medium carbon steel by uncoated cemented carbide insert. Pulse mode reduces the ...

The aim of this research project is to study the applicability of supercritical extraction with carbon dioxide to the decontamination of soils containing pesticides. In this work, after a brief but important introduction to the subject, the results of a preliminary study of the extraction of atrazine from sand with supercritical carbon dioxide are reported. These results, which were obtained wi...

The binary diffusion coefficients of ferrocene and 1,1’-dimethylferrocene at infinite dilution in supercritical carbon dioxide, D12, were measured by the chromatographic impulse response (CIR) method at temperatures from 308.2 to 323.2 K and pressures from 9 to 40 MPa. The D12 data for ferrocene were also measured by the Taylor dispersion method. The diffusion data of ferrocene measured by the ...
