Abstract

Dimethyl carbonate (DMC) is expected to be used widely,since it is a low toxic chemical. A novel preparation method of DMC, in which DMC is prepared via methyl nitrite (MN) by the oxidative carbonylation of methanol, has been developed. This method in volves two separated reactions, those are, DMC synthesis and MN synthesis. DMC is synthesized in gas phase from CO and MN over Pd(2) compound supported catalyst with generating nitrogen monoxide(NO). The MN for DMC synthesis is synthesized fromNO generated in DMC synthesis, methanoland O{sub 2}. As both of two reactions show high selectivities to DMC and MN, respectively, DMC is actually prepared from CO, methanol and O{sub 2}. According to this method DMC is prepared with high effiency and little catalyst deactivation since neither O{sub 2} nor H{sub 2}O are present over the catalyst. (author)
