Embodiment 1
[0014] Add 0.3 grams of catalyst into the reactor, feed methanol at a flow rate of 0.02 ml / min, and feed CO and o 2 , After reacting for 3 hours, the reacted mixture was separated by a gas-liquid separator to obtain a liquid phase mixture, and then the liquid phase mixture was distilled to obtain dimethyl carbonate.
Embodiment 2
[0016] Add 0.3 grams of catalyst to the reactor, feed methanol at a flow rate of 0.08 ml / min, and feed CO and o 2 , After reacting for 5 hours, the reacted mixture was separated by a gas-liquid separator to obtain a liquid phase mixture, and then the liquid phase mixture was distilled to obtain dimethyl carbonate.
Embodiment 3
[0018] Add 0.4 grams of catalyst to the reactor, feed methanol at a flow rate of 0.1 ml / min, and feed CO and o 2 , After reacting for 4 hours, the reacted mixture was separated by a gas-liquid separator to obtain a liquid phase mixture, and then the liquid phase mixture was distilled to obtain dimethyl carbonate.
