发明名称 Method for reactivating a 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, so that the re-activated catalyst composition is effective at carbonylating an aromatic hydroxy compound in a subsequent oxidative carbonylation reaction.
