Method for the production of cycloaliphatic compounds having side chains with epoxy groups by hydrogenation on ru/s102 catalysts

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 DEG C., ii) reducing the solid obtained in i) by means of hydrogen at from 100 to 350 DEG C., where step ii) is carried out directly after step i).
