<p>A process for producing an alkylene carbonate through reaction between an alkylene oxide and carbon dioxide gas, wherein as the carbon dioxide gas as raw material, use is made of carbon dioxide gas of 99.5 vol.% or higher purity recovered from at least portion of oxidation reaction waste gas resulting from recovery of ethylene oxide from oxidation reaction gas obtained by vapor-phase oxidation of ethylene. In this process, carbon dioxide gas can be effectively utilized, and the wasting of carbon dioxide gas as raw material and alkylene oxide as raw material can be reduced. Through the process, there can be produced an alkylene carbonate of high quality.</p> |
