ABSTRACT:
A method for making aromatic organic carbonate, such as diphenyl carbonate is provided which employs a transition metal catalyst in the form of a palladium catalyst mixture. The palladium catalyst can be used in combination with an organic cocatalyst, such as a terpyridine and a cobalt cocatalyst in the form of a cobalt complex containing a pentadentate ligand. The aromatic organic carbonate is separated from the carbonylation reaction mixture as a 1:1 molar adduct of aromatic organic carbonate such as diphenyl carbonate and aromatic organic hydroxy compound, such as phenol. The transition metal catalyst has been found to be recyclable allowing for the introduction of make up aromatic organic hydroxy compound into the reactor under ambient conditions.
