Abstract
Disclosed herein are new mixed metal oxide catalysts suitable as heterogeneous catalysts for catalyzing the transesterification process of aromatic alcohols with a dialkyl carbonate to form aromatic carbonates. The heterogeneous catalyst comprises a combination of two, three, four, or more oxides of Mo, V, Nb, Ce, Cu, Sn, or an element selected from Group IA or Group IIA of the periodic table.
