Abstract
Abstract Catalytically-active metallic glasses containing at least one element from a subgroup of the periodic system and at least one element from a main group of the periodic system. Process for the production of catalytically-active metallic glasses where the metallic glass is produced from at least one element from a subgroup of the periodic system and at least from one element from a main group of the periodic system. The metallic glasses are activated by self-activation or by an oxidative and/or reductive treatment. The catalytically-active metallic glasses can be used as hydration, oxidation or isomerization catalysts.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
55 words
Process for the oxidation of toluene comprising catalytically oxidizing the toluene in the presence of a catalytically effective amount of a catalytically-active metallic glass which consists of V 36 Zr 64 or V 36 Ti 64 , the metallic glass being first activated by an oxidative and/or a reductive treatment or being activated in situ.
Claim 2
Dependent Claim
55 words
Process for the oxidation of toluene comprising catalytically oxidizing the toluene in the presence of a catalytically effective amount of a catalytically-active metallic glass which consists of V 36 Zr 64 or V 36 Ti 64 , the metallic glass being first activated by an oxidative and/or a reductive treatment or being activated in situ.
Claim 3
Dependent Claim
30 words
Process as claimed in claim 1 wherein the metallic glass is V 36 Zr 64 which has been activated by treatment with an acid and which is in ribbon form.
