The production of formaldehyde by oxidizing dehydrogenation of methanol in the presence of a silver catalyst using air which has been washed with a solution of an alkali metal compound in water and methanol in specific proportions. The product is a disinfectant, tanning agent, reducing agent and a starting material for the production of synthetic resins, adhesives and plastics.

Production of formaldehyde

The manufacture of formaldehyde by oxidative dehydrogenation of crude methanol in the presence of a silver catalyst, the crude methanol being caused to impinge against baffle plates before the reaction takes place, the impurities which separate at the baffle plates being collected. The formaldehyde manufactured by the process of the invention is valuable as a disinfectant, tanning agent, reducing agent and intermediate in the manufacture of synthetic resins, adhesives and plastics.
