Amphiphiles for supercritical CO2

Biochimie, 2012
A semi-fluorinated hybrid amphiphile, pentadecafluoro-5-dodecyl (F7H4) sulfate, has been shown to form reversed micelles in dense CO(2); the aggregates evolve to form water-in-CO(2) (w/c) microemulsion droplets on addition of water. Aggregation structures in these w/c phases have been characterised by small-angle neutron scattering (SANS), showing the ...

Materials Performance in CO2 and Supercritical CO2

2020
Past and current gas-cooled nuclear reactors rely on CO2-rich gases as a coolant to transfer heat from the reactor core, while future reactors may utilize a supercritical CO2 Brayton cycle for power production. The alloys used to construct these systems can experience serious corrosion issues induced by CO2 in the high temperature portions of the ...

Supercritical CO2 fractionation of jasmine concrete

The Journal of Supercritical Fluids, 1995
Abstract Jasmine fragrance is usually produced by hexane extraction. The extraction product called a “concrete,” undergoes further processing to separate fragrance compounds from undesired coextractives such as paraffins and fatty acid methyl esters. This study reports supercritical CO 2 fractionation of jasmine concrete to avoid thermal degradation

Use of supercritical CO2 for bone delipidation

Biomaterials, 1994
Supercritical carbon dioxide was used for bone delipidation. It appeared that this technology is very efficient since supercritical CO2 is able to diffuse into microporous solids much better than liquids and that it has a good solvent capacity for lipids.

Extractive fermentation of aroma with supercritical CO2

Biotechnology and Bioengineering, 1999
This work deals with the feasibility of achieving an extractive fermentation of 2-phenylethyl alcohol, the rose aroma, coupling fermentation with Kluyveromyces marxianus and supercritical carbon dioxide (SCCO2) extraction. The extractive process is, in this case, of special interest due to the strong yeast inhibition by 2-phenylethyl alcohol.

Rose concrete fractionation by supercritical CO2

The Journal of Supercritical Fluids, 1996
Abstract Supercritical CO2 extraction was used to post-process a solid rose extract produced by liquid solvent extraction. Single step supercritical extraction at 80 bar, 40 °C, and a two-stage separation procedure at 80 bar and −16 °C and at 15 bar and 0 °C, were the optimum process conditions to produce a volatile rose oil with an overall 2-phenyl ...
