| 摘要 |
The present invention relates to a process for producing ethylene glycol from ethylene oxide wherein ethylene oxide in a gas resulting from oxidation of ethylene is absorbed in a specific absorbing solution, is allowed to react with carbon dioxide, converted into ethylene carbonate, and then subjected to hydrolysis to produce ethylene glycol. According to the present invention, a large energy consuming step such as stripping of ethylene oxide and separation of excess amounts of water during the ethylene glycol production becomes unnecessary and the process can be greatly simplified by combining the ethylene oxide absorption step and the carbonation step. |
