Abstract
A carbonic acid diester is stably and safely produced at a high selectivity and at a high yield by catalytically reacting carbon monoxide with a nitrous acid ester in a gas phase in the presence of a solid catalyst comprising a catalytic solid material carried on a solid carrier and comprising: (a) a platinum group metal and/or a compound thereof, (b) a compound of Fe, Cu, Bi, Co, Ni and/or Sn, and (c) a vanadium compound, molybdenum compound, tungsten compound, sulfuric acid and/or phosphoric acid.
Claims18
A method of producing a carbonic acid diester, characterized by catalytically reacting carbon monoxide with a nitrous acid ester in a gas phase in the presence of a solid catalyst composed of a solid carrier and a catalytic solid material carried on the carrier, and comprising:
- (a) at least one member selected from the group consisting of platinum group metals and compounds thereof;
- (b) at least one member selected from the group consisting of iron compounds, copper compounds, bismuth compounds, cobalt compounds, nickel compounds and tin compounds;
- and
- (c) at least one member selected from the group consisting of vanadium compounds, molybdenum compounds and tungsten compounds, sulfuric acid and phosphoric acid.
