Method and catalyst system for producing aromatic carbonates |
摘要 |
A method and catalyst system for economically producing aromatic carbonates from aromatic hydroxy compounds. In one embodiment, the present invention provides a method of carbonylating aromatic hydroxy compounds by contacting at least one aromatic hydroxy compound with oxygen and carbon monoxide in the presence of a carbonylation catalyst system that includes an effective amount of a Group VIII B metal source; an effective amount of a bromide composition; an effective amount of an activating organic solvent; an effective amount of a combination of inorganic co-catalysts comprising a lead source and a copper source; and an effective amount of a base.
