PRODUCTION OF CARBOXYLIC ACIDS FROM NITRILES |
| 摘要 |
<p>A nitrile, such as terephthalonitrile or nicotinonitrile is reacted with water, in the vapor phase. in the presence of a catalyst, such as supported phosphoric acid, to produce the corresponding carboxylic acid. The carboxylic acid may be separated from the gas by sublimation, preferably at a temperature above the dew point of the other components of the mixture.</p> |
