| 摘要 |
A method wherein ethylene is oxidized in the vapour phase with molecular oxygen in the presence of catalyst to produce a gas composition comprising ethylene oxide, ethylene, carbon dioxide and water vapour and wherein at least a major portion of the ethylene oxide of a stream of the gas composition is converted in a reactor system to ethylene carbonate or a mixture of ethylene carbonate and ethylene glycol, which comprises introducing the stream of the gas composition in its substantial entirety to the reactor system. |
