| titleOfInvention | Improvements in the manufacture and production of formamide |
| abstract | Formamide is prepared by passing the vapour of ammonium formate or formic acid together with free ammonia, and with or without water, over a contact mass heated to a temperature between 100 DEG and 200 DEG C. The contact mass is preferably a dehydrating agent, e.g. bauxite, and is heated to a high temperature before use. The formamide can be separated from the reaction gases by fractional cooling. |
