Problems solved by technology

However, methods for the generation of free radicals in large quantities by perylenequinone derivatives and anthraquinone derivatives under dark conditions have not been found so far.
So far, it is generally believed that perylenequinone derivatives and anthraquinone derivatives cannot generate free radicals or the yield of free radicals is too small under dark conditions, so they have no practical value at all.

Embodiment 1

[0044] Example 1 Preparation of Perylenequinone Derivatives Dark Reaction Free Radical Generating Composition

[0045] The organic solvent extract of the perylenequinone derivatives can be extracted from natural fungi, plants, and animals containing perylenequinone derivatives; or extracted from fungal mycelia cultured by artificial fermentation; or extracted from artificially cultivated plant cells Extraction; or extraction from artificially cultured animal cells; or preparation of target compounds synthesized by chemical methods. The raw materials and techniques for its preparation belong to the prior art. (See the documents submitted by the applicant with application number 021110386.0)

[0046] The composition comprises quinone derivatives (hypocrellin A, Hypocrellin A), surfactant micelles (Triton X-100) and a reducing agent with low redox potential (potato juice). Its mass composition is:

[0047] Acid derivatives: surfactant micellar solution: reducing agent with low...

Embodiment 2

[0104] Example 2 Preparation of Perylenequinone Derivatives Dark Reaction Free Radical Generating Composition

[0105] The composition comprises quinones (select hypocrellin B, Hypocrellin B), micelles (select Tween-20 in polyoxyethylene sorbitan fatty acid ester) and reducing agent (select amino acid and its derivatives substances, such as cysteine). Its mass composition is: quinones: micelles: reducing agent = 1: 50: 20; the rest are the same as in Example 1.

Embodiment 3

[0106] Example 3 Preparation of Perylenequinone Derivatives Dark Reaction Free Radical Generating Composition

[0107] Quinones (select coelomycin A, Elsinochrome A), micelles (select Tween-40 in polyoxyethylene dehydrated pitol fatty acid ester) and reducing agents (select amino acids and their derivatives, such as cysteine acid). Its mass composition is:

[0108] Quinones: micelles: reducing agent = 1:200:2. All the other are with embodiment 1.

Abstract

The present invention belongs to the field of free radical producing chemical reaction technology, and relates to the dark reaction process of quinone derivative composite to produce free radical and its application. The quinone derivative includes perylene quinone and anthraquinone, and the dark reaction process includes dispersing quinone derivative in surfactant solution, adding reductant with lower oxidation-reduction potential to form dark reaction composite for producing free radical. Under dark condition, the dark reaction composite produce great amount of active oxygen to inhibit the growth of fungi effectively in the effect higher than that of chemical sterilizer and less resistance. The present invention has wide application in preparing sterilizer and preparation for degrading dark environment pollutant.

Description

technical field [0001] The invention belongs to the technical field of chemical reactions for generating free radicals, and in particular relates to a method for generating free radicals by dark reaction of a quinone derivative composition and its application. Background technique [0002] Many quinone compounds, such as perylenequinone derivatives and anthraquinone derivatives, are photosensitizers with good performance. This type of compound can produce photosensitization under light conditions, also known as photodynamic action, that is, photosensitizers produce photosensitizers under light conditions. Active oxygen and free radicals can cause damage to organisms. This phenomenon has a wide range of applications in life and production: for example, "Journal of Photochemistry and Photobiology A: Chemistry" 1992, Volume 64, page 273 (J.Photochem.Photobiol.A:chem.1992, 64, 273), Reported the method and effect of hypocrellin A for photodynamic therapy (Photodynamic Therapy, ...
