Abstract: Formaldehyde is manufactured by oxidative dehydrogenation of methanol in the presence of a silver catalyst and of certain amounts of steam and formaldehyde, some formaldehyde and a part of the water being withdrawn from the reaction mixture and recycled. The formaldehyde manufactured by the process may be used as a disinfectant, tanning agent, reducing agent and starting material for the manufacture of synthetic resin, 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.
