Method for reactivating a deactivated catalyst composition |
摘要 |
The present invention is directed to a method for reactivating a deactivated carbonylation catalyst composition previously used in a carbonylation reaction involving an aromatic hydroxy compound, carbon monoxide and oxygen, such that the reactivated catalyst composition is effective at carbonylating an aromatic hydroxy compound in a subsequent oxidative carbonylation reaction.
