Manufacture of aqueous formaldehyde |
| abstract |
Formaldehyde manufacture by oxidative-dehydrogenation of methanol over a silver or copper catalyst. Aqueous formaldehyde solution is obtained from the reaction and is substantially stripped of methanol by a low energy process at relatively low temperature by means of recycled off-gas in a stripping column comprising at least about 1.5 theoretical transfer units for stripping methanol. |
