Method for the production of cycloaliphatic compounds (1) having side chains with epoxy groups |
摘要 |
Cycloaliphatic compounds I which have side chains containing epoxide groups are prepared by heterogeneously catalyzed hydrogenation of a compound II which comprises at least one carbocyclic aromatic group and at least one side chain containing at least one epoxide group over a ruthenium catalyst, wherein the ruthenium catalyst is obtainable by i) treating a support material based on amorphous silicon dioxide one or more times with a halogen-free aqueous solution of a low molecular weight ruthenium compound and subsequently drying the treated support material at below 200° C., ii) reducing the solid obtained in i) by means of hydrogen at from 100 to 350° C., where step ii) is carried out directly after step i).
