A process for producing an aldehyde of the invention allows a 1,2-diol (vic-diol) to react with oxygen in the presence of a ruthenium catalyst supported on a carrier to oxidatively cleave a bond between two carbon atoms, where hydroxyl groups are combined with the carbon atoms, to thereby yield a corresponding aldehyde. The carrier includes, for example, an activated carbon. As a catalytic component to be supported on the carrier, dichlorotris(triphenylphosphine)ruthenium(II), and other organic ruthenium complexes, for example, can be used. The invention can efficiently produce a corresponding aldehyde by oxidative cleavage of a 1,2-diol with oxygen.
本发明的一种醛生产工艺允许 1,2-二醇(vic-diol)在载体上支撑的钌催化剂存在下与氧气反应,氧化裂解两个碳原子之间的键,其中羟基与碳原子结合,从而生成相应的醛。载体包括活性炭等。作为支撑在载体上的催化成分,可以使用二氯三(三苯基膦)钌(II)和其他有机钌络合物等。本发明可以通过氧氧化裂解 1,2-二醇有效地生成相应的醛。
