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 the same hop sample at 300 bar and 40?C for 2.5 h (Extract B). Extraction kinetics of the system hop-

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.
