PREPARATION OF DIMETHYL CARBONATE FROM METHANOL AND CARBON-DIOXIDE IN THE PRESENCE OF ORGANOTIN COMPOUNDS

Dibutyltin dialkoxides react with methanol and carbon dioxide to give dimethyl carbonate in 60 to 220 mole % yields with respect to the organotin compound. The higher yields of the carbonate (150 up to 330 mole %) have been achieved with the use of chemical scavengers of the reaction water.
