Abstract

The invention discloses a preparation method of a disinfectant perglutaric acid. The disinfectant perglutaric acid is prepared from the following components in parts by mass: 21 to 31 parts of sodiumpercarbonate, 15 to 22 parts of urea peroxide, 40 to 60 parts of purified water, 40 to 60 parts of glutaric acid, 0.001 to 0.05 part of 1, 3-propylene glycol and 0.01 to 0.05 part of sodium nitrite. According to the invention, the perglutaric acid produced by the method is a liquid preparation, the preparation process is simple, the content can be up to 98% or above, the liquid preparation is moreconvenient to use compared with solid perglutaric acid, dissolution, dilution and activation are not needed, the influence of temperature is avoided, and the solid perglutaric acid needs to be dissolved in warm water of 50 DEG C quickly when being used; compared with solid perglutaric acid powder, liquid perglutaric acid is safe to use, and the risk of dust explosion is avoided; and the perglutaric acid disinfectant is high in purity, good in stability and free of pungent smell, the stabilizer of perglutaric acid is uniquely added in the synthesis process, the normal-temperature storage validity period of the disinfectant can reach 3 years, and the 3-year content reduction rate is smaller than 10%.

Description

technical field [0001] The invention relates to the field of disinfectant technology, in particular to a preparation method of disinfectant perglutaric acid. Background technique [0002] Peroxides are widely used in the field of medical disinfection at home and abroad, because of their strong oxidizing properties, they have a good killing effect on bacteria and viruses at extremely low concentrations. At present, there is a published patent in Germany DE2654164 A method of using glutaric anhydride and hydrogen peroxide to synthesize peroxyglutaric acid liquid formulations, the product content can reach up to 60%, overcomes the shortcomings of peracetic acid fungicides, the disinfectant has a strong bactericidal effect and is relatively stable. Low toxicity, no irritating smell, basically no volatility, it is an ideal disinfectant. But the perglutaric acid content that this invention produces is low, is about 50%, is aqueous solution, and stability is not ideal enough, is i...
