开发了一种新型的高活性固载化钌催化剂，该催化剂可成功地用于醇氧化制醛、酮。与大多数固定化催化剂相反，Ru催化剂具有比原始非固定化催化剂更高的活性。在间歇系统中，Ru催化剂被回收并重复使用几次而不损失活性。该催化剂也被应用到流动系统，其中表现出优异的转化率和产率。在这两种情况下都没有观察到钌的浸出。
A novel, highly active immobilized ruthenium catalyst, which can be successfully used in oxidation of alcohols to aldehydes and ketones, has been developed. In contrast to most immobilized catalysts, the Ru catalyst has activity that is higher than that of the original nonimmobilized catalyst. In a batch system, the Ru catalyst was recovered and reused several times without loss of activity. The catalyst was also applied to a flow system, in which excellent conversions and yields were demonstrated. No leaching of Ru was observed in both cases.
