WERKWIJZE TER BEREIDING VAN ETHYLEENGLYCOL. |
摘要 |
A process for the preparation of ethylene glycol by the vapor phase hydrogenation of oxalate esters, such as a dibutyl oxalate, at elevated temperatures and at relatively low hydrogen pressures in the presence of a suitable hydrogenation catalyst, such as a copper chromite catalyst, while minimizing the hydrogenolysis of the glycol and other side reactions and maximizing the hydrogenation catalyst activity. |
