Definitions
- Oxygen-producing mixture and a process for the enzymatic production of peracids are used in oxidation reactions for the production of chemical compounds. Such mixtures are also effective as oxidative bleaches in detergent compositions.
- the process according to the invention can be used in particular in the synthesis of organic compounds in which the peracid formed in situ participates as an oxidizing reaction partner.
- peracid production takes place via the reaction of acid anhydrides and acid halides with hydrogen peroxide.
- peracids can be produced from carboxylic acids and hydrogen peroxide in the presence of mineral acids.
- the Persaurs are extremely unstable. When heated, such connections can explode without warning.
- this system first sets an elaborate synthesis of defined compounds - here Glyzerideuren - expected.
- longer-chain peracids develop here, whose reactivity towards low-chain organic peracids is reduced.
- the temperature range of such enzymatic systems is also restricted, which limits their use as bleaching agents, for example in the case of full and cold detergents.
- the object of the invention is to produce enzymatically organic peracids in a simple manner and to provide a mixture as a supplier of active oxygen for a wide variety of applications.
- the enzymatic, active oxygen-producing mixture consists of
- Oxidoreductase with an ⁇ / ⁇ hydrolase fold and a catalytic triad of the amino acids serine, histidine and aspartic acid a peroxide source and an organic acid or its salt
- the peroxide source is kept separate from the other components.
- the enzyme according to the invention can be freeze-dried and stored at room temperature for a long time, the enzyme can e.g. be used in conjunction with sodium acetate and sodium perborate in a solid mixture.
- the enzyme catalyzes the conversion of the organic acid into peracid with the participation of the peroxide source.
- the enzymes used according to the invention can be isolated from different organisms (pro and eukaryotes).

- the organic acid used is preferably mono- and dicarboxylic acids and hydroxycarboxylic acids with 2 to 4 carbon atoms, such as, in particular, acetic acid, propionic acid or lactic acid or salts thereof.
- Hydrogen peroxide or compounds releasing hydrogen peroxide, such as perborates, in particular sodium perborate, percarbonates, in particular sodium percarbonate, and persulfates are preferably used as the peroxide source.
- the amount of enzyme used depends on the volume of the overall system and is preferably 0.15 to 50 ⁇ mol Hydrogen peroxide and 8 to 16 mU enzyme per 100 ⁇ mol acid or salt. If another peroxide source is used instead of hydrogen peroxide, for example sodium perborate, the amount to be used relates to the hydrogen peroxide released therefrom.
- the enzyme unit U denotes the amount of enzyme that converts one ⁇ mol substrate per minute.
- the pH range of the mixture according to the invention is buffered in the range 3.5 to 6 by the organic acid or its salts involved.
- the application temperature of the mixture according to the invention can be between 20 and 80 ° C., depending on the enzyme used.
- the oxidoreductases according to the invention have the same structural features, namely an ⁇ / ⁇ hydrolase fold and a catalytic triad of the amino acids serine, histidine and aspartic acid.
- the bacterial non-heme haloperoxidases used in contrast to the hemoperoxidases containing heme, do not require a heme group as a prosthetic group and, in contrast to the eukaryotic non-heme
- Haloperoxidases also have no metal ions or other cofactors for their activity.
- the enzymes according to the invention form peracids by hydrolysis of a serine ester in conjunction with hydrogen peroxide, which then act as an oxidizing agent.
- the ester is formed by reaction of the organic acid with a serine residue in the active center of the enzyme.
- the oxidoreductases used according to the invention can easily be prepared in large amounts by cloning the genes and overexpression.
- the mixture according to the invention can be used in various ways due to its oxidative effect, e.g. B. in the Synthesis of organic compounds, or generally as an oxidation reagent.
- Such an area of application is bleaching agents, for example bleaching agents for paper and textiles, in particular for bleaching processes in the acidic to neutral pH range.
- the mixture according to the invention is also suitable as a disinfectant for disinfecting aqueous solutions and surfaces or for producing disinfectants.
- the peracids formed in situ from the mixture according to the invention react by oxidation with contaminants, coloring components and microorganisms.
- the process for the enzymatic production of organic peracids is carried out in such a way that
- bacterial non-heme haloperoxidase e.g. B. chlorine peroxidase or bromine peroxidase, hydrogen peroxide or sodium perborate as the peroxide compound and acetic acid or propionic acid or lactic acid or its salts as the organic acid.
- the enzyme content is preferably 0.1 to 50 ⁇ mol hydrogen peroxide and 100 ⁇ mol acid or salt 8 to 16 mU enzyme. If sodium perborate is used instead of hydrogen peroxide, the amount to be used relates to the hydrogen peroxide released therefrom.
- the peracid produced by the process according to the invention is extremely reactive. It oxidizes compounds or decomposes to form active oxygen and free acid. The active oxygen can thus be used as a reaction partner.
- the peracid formed in situ can also be detected by such oxidation reactions, for example by oxidation of aniline to nitrobenzene.
- oxidation reactions for example by oxidation of aniline to nitrobenzene.
- halide ions these are oxidized in situ and in the presence of substrates suitable for electrophilic substitution, halogenation reactions occur. Irrespective of the fact that the peracids formed in situ can be detected via the aforementioned oxidation reactions, these examples show an advantageous field of application of the method according to the invention in the synthesis of organic compounds.
