<p>Formaldehyde is prepared by oxidative dehydrogenation of methanol in the presence of a silver catalyst, specific amounts of steam and specific amounts of an off-gas, of a specific composition, taken from the manufacture of formaldehyde. The reaction is started at a lower throughput of methanol and at a lower temperature. The formaldehyde obtainable by the process is a disinfectant, tanning agent and reducing agent, and a starting material for the manufacture of synthetic resins, adhesives and plastics.</p> |
