Process for the hydrogenolysis of C--O and C.dbd.O bonds in organic substances
First Claim
1. A process for the hydrogenolysis of a compound represented by the structural formula I or II to give a compound represented by the structural formula III or IV ##STR3## comprising reacting I or II with hydrogen in the presence of a catalyst system that is a solid catalyst which contains at least one metal from Group VIII and/or Group IB of the Periodic System of Elements on a support consisting of at least one solid acid with an acid activity index of at least 90%, wherein the substituents R1 to R8, are the same or different, and are each a member selected from the group consisting of hydrogen, alkyl, substituted or non-substituted aryl, hydroxyl, alkoxy, substituted or non-substituted aryloxy, halogen, carboxyl, a carboxylic acid derivative group, acyloxy, nitro, a sulphonic acid, mercapto, amino, alkyl-substituted amino and substituted or non-substituted aryl-substituted amino.

Abstract
A process for hydrogenolysis of C--O and C═O bonds in organic substances by reaction with hydrogen in the presence of a catalyst system which contains at least one metal from Groups VIII and/or IB of the Periodic System of Elements on a support consisting of at least one solid acid with an acid activity index of at least 90%.

12. A process for the hydrogenolysis of a compound represented by the structural formula I or II to give a compound represented by the structural formula III or IV and which does not require use of corrosive media ##STR4## comprising reacting I or II with hydrogen in the presence of a catalyst system that is a solid catalyst which contains at least one metal from Group VIII and/or Group IB of the Periodic System of Elements on a support consisting of at least one solid acid with an acid activity index of at least 90%, said acid activity index determinable by passing a gas stream consisting of 5 vol. % isopropanol and 95% vol. % helium through 100 grams of catalyst particles of a size range of 0.5 to 2.0 mm and with a flow rate of 50 ml/minute to thereby decompose said isopropanol to propene and water and then measuring the degree of conversion of isopropanol at 250°
- C., wherein the substituents R1 to R8, are the same or different, and are each a member selected from the group consisting of hydrogen alkyl, substituted or non-substituted aryl, hydroxyl, alkoxy, substituted or non-substituted aryloxy, halogen, carboxyl, a carboxylic acid derivative group, acyloxy, nitro, a sulphonic acid, mercapto, amino, alkyl-substituted amino and substituted or non-substituted aryl-substituted amino.
