    摘要: 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.
