| titleOfInvention | Method for purifying adipic acid in water |
| abstract | The present invention discloses a process for purifying adipic acid in water. More specifically, the present invention discloses an improvement in the crystallization or recrystallization of adipic acid in water, characterized in that the crystallization or recrystallization is carried out in the presence of a strongly protic acid and / or carbon monoxide. Crystallization or recrystallization can in particular reduce the content of trace metal catalysts of adipic acid. |
