Abstract: A process for producing formaldehyde by oxidizing dehydrogenation of methanol in the presence of a silver catalyst, wherein a vaporous mixture of water and oxygen is introduced into the vaporous starting mixture containing water, methanol and oxygen before entry into the catalyst bed. Formaldehyde produced by the process is a disinfectant, tanning agent, reducing agent and raw material for the production of synthetic resins, adhesives and plastics.
