Process for the selective hydrogenation of aromatic groups in presence of epoxy groups.

摘要

The aromatic gp. of an organic molecule contg. an aromatic gp. and an epoxy gp. is hydrogenated using hydrogen in the presence of a ruthenium-contg. catalyst and 0.2-10 wt.% water wrt. reaction components. Pref. the catalyst comprises ruthenium hydroxide. Pref. di(p-glycidoxylphenyl) methane or 2,2-di(p-glycidoxylphenyl)propane is hydrogenated. The reaction may be carried out at 40-70 deg.C.
