ABSTRACT:
The present disclosure is directed to a catalyst composition used in the production of aromatic carbonates, and in particular to a catalyst composition which comprises an activating solvent. In one embodiment the disclosure relates to a catalyst composition which comprises to a combination of two activating solvents, a first activating solvent chosen for its coordinative properties, and a second activating solvent chosen for its dielectric constant properties. In alternative embodiments, the present disclosure also pertains to a method for producing aromatic carbonates using the catalyst compositions disclosed herein.
