In a process to avoid the formation of waste water in the production of hexamine from ammonia and the stream of gas containing formaldehyde resulting from the catalytic oxidation of methanol on metallic oxide catalysts, or by oxidative dehydrogenation to formaldehyde, the liquid volume during reaction for the production of hexamine is kept constant, and carbon monoxide, the organic components of the exhaust gas and also hydrogen, if present, are oxidized to carbon dioxide and water, thus avoiding an energy-consuming condensation of the condensable components from the stream of exhaust gas and their treatment.
