Description

Unitary peroxyacetic acid disinfectant and preparation method thereof
Technical Field
The invention belongs to the technical field of disinfection, and particularly relates to a monoperoxyacetic acid disinfectant and a preparation method thereof.
Background
The peroxyacetic acid solution is an oxidative green ecological bactericide, is a novel sporicide compared with the traditional disinfectant, generally consists of peroxyacetic acid, hydrogen peroxide and acetic acid, and mainly contains the peroxyacetic acid as an active ingredient. It destroys the outer cell membrane and cell wall of microorganism by oxidation, so that the enzyme system is destroyed, the microorganism is inactivated, the peracetic acid can permeate the polypeptide shell of spore, and destroy the macromolecules in spore, such as saccharide, nucleic acid, lipid, etc., finally causing cell lysis and death. The peroxyacetic acid sold in the current market is of two types, one type is binary, the product is divided into A, B components, the A liquid is glacial acetic acid and sulfuric acid, the B liquid is hydrogen peroxide, the two components are separately stored at ordinary times, the A, B components are mixed according to a certain proportion before use, the mixture is reacted to generate peroxyacetic acid solution, and the peroxyacetic acid solution is diluted to the required concentration for use after being placed for 24 to 48 hours.
However, the concentration of peracetic acid after mixing decreases relatively quickly, and the tendency to decrease increases with increasing concentration of peracetic acid. Therefore, in practical application, the preparation can be carried out only according to the required amount of the peroxyacetic acid, which brings great inconvenience to the use and limits the application of the peroxyacetic acid. The other is a primary peroxyacetic acid, which overcomes the defects that some secondary peroxyacetic acids have poor stability, need to be prepared on site, need to be operated by professional personnel, are extremely inconvenient to use and cannot be marketed on a large scale, but the improvement of the stability is a great technical problem in the disinfection field.
