| titleOfInvention | Process for the simultaneous preparation of concentrated aqueous formaldehyde-urea solutions and formaldehyde solutions |
| abstract | Process for the simultaneous production of concentrated, aqueous formaldehyde solutions and formaldehyde / urea solutions by oxidizing dehydrogenation of methanol with air in the presence of a silver catalyst at elevated temperature, subsequent three-stage absorption of the formaldehyde formed in aqueous formaldehyde / urea solution, then in concentrated, aqueous formaldehyde solution, and then in dilute, aqueous formaldehyde solution under certain conditions with regard to concentration of the absorption solutions, temperature and pH, portions of formaldehyde and water being removed from the absorption mixture from the third absorption stage and being returned to the reaction. The formaldehyde which can be prepared by the process of the invention is a disinfectant, tanning agent, reducing agent and valuable starting material for the production of synthetic resins, adhesives and plastics. |
