Abstract: 1425751 Formaldehyde BADISCHE ANILIN- & SODA-FABRIK AG 25 June 1973 [26 June 1972] 30012/73 Heading C2C In a process for producing formaldehyde by oxidizing dehydrogenation of methanol in the presence of a silver catalyst at elevated temperature, the reaction is carried out at a temperature of 550‹ to 750‹ C. and during the reaction an additional vapour mixture of oxygen and water heated to at least 70‹ C. and providing 0À05 to 0À8 mole of water and of 0À005 to 0À06 mole of oxygen (O 2 ) based on 1 mole of feed methanol, is introduced into the vaporous starting mixture which has been heated to at least 60‹ C. and contains from 0À09 to 1À8 moles of water and 0À35 to 0À5 moles of oxygen (O 2 ) per 1 mole of methanol before said starting mixture enters the catalyst bed, the space velocity being 0À9 to 3 metric tons of methanol per square meter of catalyst bed cross-section per hour. The plant may consist of a plurality of reactors in parallel, and not all the reactors need be operated according to the invention, at least not all the time. The reaction temperature may be raised in steps. Baffles at which impurities collected and removed may be provided downstream of the point of introduction of the additional vapour mixture but upstream of the catalyst bed.

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.
