Supercritical carbon dioxide (scCO2) is an effective reaction medium to perform the oxidation of primary and secondary aliphatic alcohols to the corresponding carbonyl compounds with chromium trioxide supported on silica. These reactions were performed by flowing a solution of the alcohol in scCO2 through a column containing the supported reagent and recovering the product by depressurization. This

三氧化铬将伯和仲脂族醇氧化为相应的羰基化合物。通过使醇在sc CO 2中的溶液流过含有负载的试剂的柱并通过减压回收产物来进行这些反应。这种方法避免了使用有机溶剂,避免了产品被
铬污染。
