WERKWIJZE TER BEREIDING VAN ETHYLEENGLYCOL DOOR KATALYTISCHE HYDROGENERING. |
| 摘要 |
The life of the hydrogenation catalyst in reducing a mixture of glycolate ester to ethylene glycol can be extended by lowering the polyglycolide ester content of the mixture by transesterification, that is, heating in the presence of alcohol, after which the resulting mixture is hydrogenated. |
