Definitions
- metal complex compounds as catalysts for oxidation using molecular oxygen or air
- the present invention relates to the use of metal complex compounds having terpyridine ligands as oxidation catalysts for oxidation processes using molecular oxygen and/or air and also to formulations comprising such metal complex compounds.
- the metal complex compounds are used especially for bleaching various substrates, for example in the treatment of stains on textile material, without at the same time causing any appreciable damage to fibres and dyeings.
- peroxide-containing bleaching agents have been used in washing and cleaning processes. They have an excellent action at a liquor temperature of 90°C and above, but their performance noticeably decreases with lower temperatures.
- peracid precursors are used to activate peroxide-containing bleaching agents.
- Tetraacetyl ethylene- diamine is mainly used as the activator in European washing systems.
- US systems are frequently based on sodium nonanoylbenzosulfonate (Na-NOBS).
- Activator systems are effective in general, but possess a number of disadvantages. Inter alia, activators must be used in stoichiometric amounts. Large quantities are therefore required and the bleaching components take up a great deal of space in the detergent.
- the bleaching action of currently customary activators is often inadequate under certain but desirable washing conditions (e.g. low temperature, short wash cycle).
- transition metal complexes are capable of activating hydrogen peroxide and thus accelerating bleaching processes.
- WO00/60043 describes ethylenediamine derivatives as transition metal complexes in bleaching processes that use atmospheric oxygen, e.g. in bleaching stains on laundry.
- WO01/16272 describes triazocycloalkyl compounds, especially triazacyclononane derivatives, as transition metal complexes in bleaching processes that use atmospheric oxygen, e.g. in bleaching stains on laundry.
- metal complexes with selected terpyridine ligands are capable of acting as catalysts in oxidation processes that use molecular oxygen and/or air in various fields of use.
- the advantage of those compounds is that, in use, they have a catalytic action and can therefore be used in small amounts.
- neither an activator component nor a peroxide component is required, which is advantageous in terms of the environmental properties.
- the invention accordingly relates to the use, as catalysts for oxidation reactions using molecular oxygen and/or air, of at least one metal complex of formula (1)
