More Information
Summary:A method and catalyst system for economically producing aromatic carbonates from aromatic hydroxy compounds is disclosed. 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 at least one Group 8, 9, or 10 metal source; an effective amount of at least one bromide composition; an effective amount of at least one activating organic solvent; an effective amount of a combination of inorganic co-catalysts comprising at least one titanium source and at least one copper source; and an effective amount of at least one base.
