摘要
The synthesis of dimethyl carbonate (C<sub>3</sub>H<sub>6</sub>O<sub>3</sub>) by the reactions of methanol carbonylation over carbon-supported palladium catalysts at atmospheric pressure is studied in this letter. Therein methyl nitrite (CH<sub>3</sub>ONO) was introduced as a cyclic reagent in the heterogenous catalytic reactions. Since <sup>+</sup>NO in methyl nitrite
