| titleOfInvention | Method of mking nitriles from carboxylic acids |
| abstract | Nitriles and dinitriles of monocarboxylic and dicarboxylic acids are produced by evaporating the acid in a film-forming evaporating apparatus, which is preferably made of titanium or stainless steel, in the presence of 0.26 to 40 moles of superheated steam per mole of carboxylic acid, the evaporated acid and steam being then mixed with 4 to 60 moles of gaseous ammonia per mole of carboxylic acid and reacted in the gaseous phase at a temperature between 260* to 500* C. in the presence of a dehydrating catalyst. |
