Challa, Prathap published the artcileCoupling of CH3OH and CO2 with 2-cyanopyridine for enhanced yields of dimethyl carbonate over ZnO-CeO2 catalyst, Safety of Picolinonitrile, the main research area is methanol carbon dioxide cyanopyridine dimethyl carbonate.
The present work is aimed to produce di-Me carbonate by coupling of CH3OH and CO2 with 2-cyanopyridine over ZnO-CeO2 catalysts prepared by co-precipitation method. These catalysts were characterized by XRD, TEM, UV-Vis DRS, BET surface area, CO2 and NH3-TPD techniques and applied for the titled reaction. Among the investigated catalysts 10ZnO-90CeO2 catalyst with CeO2 crystallite size 8.0 nm exhibited 96% conversion of methanol with 99% selectivity to di-Me carbonate. The superior catalytic activity is a unified effect of crystalline size of CeO2 and presence of an optimum number of acidic and basic sites. This protocol offers enhanced conversion of methanol with the simultaneous conversion of 2-cyanopyridine into 2-picolinamide by removing water mols. formed in the reaction.
