摘要

DIARILY CARBONATE PRODUCTION PROCESS, METHOD FOR REACTIVATING SOLID CATALYST COMPOSITION, AND SOLID CATALYST COMPOSITION. A process for the production of various organic carbonates by performing the vapor / double liquid phase transesterification and disproportionation reactions preferably in the presence of solid catalyst composition selected from the group consisting of oxides, hydroxides, oxyhydroxides or alkoxides of two. to four elements of group IV, V, VI of the Periodic Table supported on porous material having surface hydroxyl groups and the method for reactivating the catalyst deactivated by polymer deposition by contacting the deactivated catalyst with a solution of hydroxy containing compound in a solvent, such as benzene or THF.
