摘要:
An α-oxocarboxylate is manufactured by vapor-phase oxidation of α-oxoaldehyde and/or α-hydroxyaldehyde (which may have been formed by vapor-phase oxidation of 1,2-diol) with an alcohol or olefin using oxygen and a catalyst. This method provides an economical and effective route for α-oxocarboxylate manufacture from such inexpensive diols as ethylene glycol and propylene glycol.
