Title:
超臨界または未臨界二酸化炭素により膨張した有機溶媒中での遷移金属錯体による有機基質の接触酸化
Document Type and Number:
Japanese Patent JP2004500418
Kind Code:
A
Abstract:
Improved oxidation methods are provided wherein a reaction mixture comprising a substrate to be oxidized (e.g., phenols, alkenes) and an oxidation catalyst (typically dispersed in an organic solvent system) is supplemented with a compressed gas which expands the reaction mixture, thus accelerating the oxidation reaction. In preferred practice pressurized subcritical or supercritical carbon dioxide is used as the expanding gas, which is introduced into the reaction mixture together with an oxidizing agent. The inventive methods improve the substrate conversion and product selectivity by increasing the solubility of the oxidizing agent in the reaction mixture.
