Verfahren zur kontinuierlichen Oxydation aromatischer, oxydierbare Seitenketten enthaltender Verbindungen

摘要

In a continuous process for side-chain oxidation of benzene or pyridine compounds to the carboxylic acids with HNO3, cooling is effected by recirculating part of the cooled reaction filtrate. Numerous benzene and pyridine compounds are listed as starting materials, but the examples relate to the production of terephthalic acid.
