| 摘要 |
A halogenated compound I containing one or more >C=O, olefinic and/or aromatic >C=C< groups is hydrogenated for producing a halogenated compound II having no or a decreased level of >C=O, olefinic and/or aromatic >C=C< groups. In the hydrogenation process a liquid feed stream comprising one or more of these compounds I is contacted with a hydrogen-rich gaseous stream and a liquid recycle stream comprising one or more of these compounds II in the presence of a catalyst. |
