Heterogeneous ruthenium catalyst, nucleus-hydrogenated diglycidyl ether of bisphenols a and f, and method for the production thereof

A heterogeneous ruthenium catalyst comprising silicon dioxide as support material, in which the percentage ratio of the Q2 and Q3 structures Q2/Q3 in the silicon dioxide determined by means of solid-state 29Si-NMR is less than 25, a process for preparing a bisglycidyl ether of the formula I where R...

Beschreibung
Zusammenfassung:	A heterogeneous ruthenium catalyst comprising silicon dioxide as support material, in which the percentage ratio of the Q2 and Q3 structures Q2/Q3 in the silicon dioxide determined by means of solid-state 29Si-NMR is less than 25, a process for preparing a bisglycidyl ether of the formula I where R is CH3 or H, by ring hydrogenation of the corresponding aromatic bisglycidyl ether of the formula II in which the abovementioned heterogeneous ruthenium catalyst is used, and a bisglycidyl ether of the formula I which can be prepared using the abovementioned process.
