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.

Abstract: The production of combustion gas containing little or no carbon black by mixing a starting mixture of oxygen and methanol with more oxygen in specific proportions, igniting the mixture thus prepared and incompletely burning the methanol in the flame formed. The gas may be used advantageously in all cases where deposition of soot would be troublesome. It may be used with advantage for heating catalysts in catalytic syntheses, for example silver catalysts to be used for catalyzing the reaction of methanol with oxygen to form formaldehyde.
