Heterogeneous ruthenium catalyst, useful for hydrogenating bis-glycidyloxyphenyl-alkanes to cyclohexane analogs, for use in lacquers, has silica carrier with specific nuclear magnetic resonance characteristics

摘要

Heterogeneous ruthenium catalyst (A) comprises silicon dioxide (B) as carrier, in which the percentage ratio of signal intensities of the Q2 and Q3 structures, determined by 29Si solid-state NMR, is below 25. Independent claims are also included for: (1) method for preparing bis-glycidyl ethers of formula (I) by hydrogenating the corresponding aromatic compounds (II) in presence of (A); and (2) bis-glycidyl ethers of formula (I). R : hydrogen or methyl. [Image].
