摘要: The aim of this study was to elucidate the catalytic partial oxidation propane oxygenates on vanadyl pyrophosphate ((VO)2P2O7) in dense carbon dioxide acting as a solvent. reaction carried out continuous flow experiments at 673 K molar ratio CO2 :synthetic airpropane 86131, residence time 19 s and sub- supercritical pressures ranging from 2.4 9.7 MPa. tests revealed formation acrylic acetic acid besides total products. selectivity increased with rising pressure, whereas that decreased. These results may be attributed diverging adsorption both which investigated by fluid chromatography. Additionally, critical data feed product mixture were determined high-pressure optical cell opalescence method.
