Process for continuous production of organic carbonates or organic carbamates and solid catalysts therefore

摘要: Processes for the alcoholysis, inclusive of transesterification and/or disproportionation, reactants are disclosed. The alcoholysis process may include feeding and a trace amount soluble organometallic compound to reactor comprising solid catalyst, wherein catalyst each independently comprise Group II VI element, which be same element in various embodiments. As an example, diphenyl carbonate continuously produced by performing over followed where is fed reactor. Also disclosed reactivating spent such as useful transesterifications disproportionations, including removing polymeric materials deposited on re-depositing catalytically active metals catalyst.
