Supercritical carbon dioxide hop extraction [PDF]
Acta Periodica Technologica, 2005 The hop of Magnum cultivar was extracted using supercritical carbon dioxide (SFE-as extractant). Extraction was carried out in the two steps: the first one being carried out at 150 bar and 40°C for 2.5 h (Extract A), and the second was the extraction of ...

Synthesis of dimethyl carbonate in supercritical carbon dioxide [PDF]
Brazilian Journal of Chemical Engineering, 2006 The reactivity of carbon dioxide with methanol to form dimethyl carbonate was studied in the presence of the n-butylmethoxytin compounds n-Bu3SnOCH3, n-Bu2Sn(OCH3)2 , and [n-Bu2(CH3O)Sn]2 O. The reaction occurred under solventless conditions at 423 K and was produced by an increase in CO2 pressure.

Sterilization of microorganisms with supercritical carbon dioxide. [PDF]
Agricultural and Biological Chemistry, 1987 The sterilizing effect of supercritical carbon dioxide (SC-C02) is described as compared with gaseous C02(G-C02) and liquid C02(L-C02). Baker’s yeast, Escherichia coli, Staphylococcus aureus and conidia of Aspergillus niger were sterilized by treating with SC-C02 at 200 atm and 35°C when the water content of each microorganism was 70 ~ 90%.

Continuous Formation of Limonene Carbonates in Supercritical Carbon Dioxide
Organic Process Research & Development, 2022 We present a continuous flow method for the conversion of bioderived limonene oxide and limonene dioxide to limonene carbonates using carbon dioxide in its supercritical state as a reagent and sole solvent. Various ammonium- and imidazolium-based ionic liquids were initially investigated in batch mode.
