Abstract
There is provided a catalyst for dimethyl carbonate synthesis which has a high conversion rate under the supercritical condition of COand can be handled easily. The catalyst for dimethyl carbonate is obtained by loading SOor POon a carrier composed of a compound having a solid acid site, and is used to produce dimethyl carbonate from acetone dimethyl carbonate and COin a supercritical state. The component having a solid acid site is preferably one or more of ZrO, AlO, and TiO.
