Abstract

The present invention relates to a method for producing stable and easily identifiable peracetic acid using an anthraquinone compound structurally, and to an agricultural disinfectant containing easily identifiable peracetic acid, comprising a) a first-stage reaction in which acetic acid and hydrogen peroxide are sequentially introduced and reacted, b) a second-stage reaction in which a stabilizer is introduced and reacted with the reaction product of the first stage, and c) a third-stage reaction in which an anthraquinone-based compound is introduced and aged to produce colored peracetic acid, and the agricultural disinfectant containing easily identifiable peracetic acid containing colored peracetic acid produced according to the above method as an active ingredient. Acetic peroxide produced according to the manufacturing method of the present invention has the advantage of being easily identifiable visually during use, allowing anyone to easily identify and use it as an agricultural disinfectant. Additionally, the anthraquinone compound used in the present invention is stable against acetic peroxide, so it has the characteristic of being able to be stored and used for a long time without a change in color. Furthermore, the agricultural disinfectant has the advantage of allowing additional effects such as plant growth, seed germination, and control of soil-borne diseases to be expected through the action of the anthraquinone compound.

Description

Method for producing peracetic acid easily identifiable by eye The present invention relates to a method for manufacturing peracetic acid (PAA) that is easily identifiable by visual inspection, and specifically, to a method for manufacturing peracetic acid for use as a disinfectant that is easily identifiable by visual inspection. Peracetic acid (PAA) is a powerful oxidizing agent and disinfectant that is utilized in various fields, such as as a pesticide or preservative to eliminate mold, bacteria, and pests, and especially as an insecticide in organic farming. It is evaluated as a very useful chemical that can minimize environmental pollution due to its characteristic of decomposing into water and carbon dioxide without leaving any residue in the environment after use. The aforementioned acetic peroxide is a colorless liquid that is not easily distinguishable from water and can be identified by its strong smell, but since acetic peroxide used as an agricultural fungicide is a high-concentration product, it is not desirable to identify it by inhaling the vapor through the nose as it is harmful to the human body. Generally, food colorings registered as food additives are used to distinguish products such as food during manufacturing, but acetic peroxide is a strong oxidizing agent and a decolorizing agent, so it reacts chemically with these food colorings, causing the color to gradually fade over time. Additionally, a significant number of inorganic dyes contain metals, which may accelerate the decomposition of acetic peroxide, making them unsuitable for use. For example, prior art related to the visual identification of peracetic acid includes Patent Document 1, which discloses a disinfectant system characterized by comprising: (a) a first portion comprising a first reagent in a carrier medium; and (b) a second portion that is miscible with the first portion and comprises a second reagent in a carrier medium; wherein the first reagent and the second reagent react when the first portion and the second portion are mixed to provide a chlorine dioxide disinfectant composition; wherein the first portion or the second portion further comprises a dye that is oxidized in the presence of chlorine dioxide to produce a visible color change when the first portion is mixed with the second portion; wherein the color change does not occur when the dye-containing portion is exposed to a disinfectant composition containing hydrogen peroxide and/or peracetic acid; and wherein the dye comprises an anthocyanin dye, an anthocyanidin dye, or a betanin dye. In addition, other prior art cannot be presented, but as a close art, Patent Document 2 discloses a method for labeling and identifying petroleum products or solvents characterized by including one or more labeling substances selected from unsaturated fatty acids, carboxylic acids, and alkylphenols that have excellent dispersibility in oil or solvents to label a product, adding a color-developing agent composed of metal ions to form a complex compound to develop color, and performing quantitative analysis; and Patent Document 3 discloses a liquid pesticide composition comprising a pesticide and a colorant, characterized in that the weight ratio of the powders of the pesticide and the colorant is 1:1 to 1:10. The inventor of the present invention manufactured a colored peracetic acid disinfectant using an anthraquinone compound that is structurally stable and can be used as a colorant, and completed the present invention. The present invention is described in detail below through specific details for implementing the invention, but the present invention is not limited by the description below. The method for producing peracetic acid that is easily identifiable by the naked eye according to the present invention comprises a) a first-step reaction in which 10 to 50 parts by weight of acetic acid ( CH₃COOH ) and 50 to 90 parts by weight of hydrogen peroxide ( H₂O₂ ); b) a second-step reaction in which 0.1 to 2 parts by weight of a stabilizer are reacted with 100 parts by weight of the first-step reactant; and c) a third-step reaction in which 0.01 to 2 parts by weight of an anthraquinone compound are added with 100 parts by weight of the second-step reactant and aged at 20 to 40°C for 12 to 72 hours to produce colored peracetic acid. The first step reaction according to the present invention is a reaction for the production of peracetic acid, and for a stable reaction, it is preferable to perform an efficient reaction while controlling the reaction by adding hydrogen peroxide (H₂O₂ ) in 3 to 5 divided steps. The stabilizer added in the second step reaction of the present invention is selected from one or more components from aliphatic dicarboxylic acid, aliphatic tricarboxylic acid, diphosphoric acid, and phosphorylated carboxylic acid. Examples of the above aliphatic dicarboxylic acids include malonic acid, succinic acid, oxalic acid, tartaric acid, maleic acid, and diglycolic a
