Production of carboxylic acids from nitriles |
摘要 |
A nitrile, such as terephthalonitrile or nicotinonitrile is hydrolyzed, in the vapor phase, in the presence of a solid acid catalyst, with ammonia which is evolved in the reaction and absorbed by the catalyst being stripped from the catalyst to reduce the production of intermediate amide products.
