Problems solved by technology

According to the method disclosed by the former, the coated tetraacetylethylenediamine and the coated sodium perborate are mixed in a certain molar ratio, and then the mixed solid is dissolved in a certain amount of normal temperature water to prepare peroxygen. Acetic acid, though solved difficult storage, the problem of transportation and inconvenient use, but solubility is poor, preparation speed is slow, and active ingredient is volatile; And the method disclosed by the latter will contain N-acetyl activator...

Abstract

The invention provides a peroxyacetic acid generator which consists of acetylsalicylic acid, tetraacetylethylenediamine, sodium percarbonate, a surfactant, a corrosion inhibitor and a pH regulator at a mass ratio of 1:(1.5-2.0):(3.5-5):(0.02-0.05):(0.1-0.3):(3-6). Meanwhile, the invention also discloses a preparation method of the peroxyacetic acid. Through the invention, by adding the pH regulator, the pH value of the mixed solution is stabilized at about 7-8, and then the prepared peroxyacetic acid solution has higher stability and lower corrosivity.

Description

technical field [0001] The present invention belongs to the technical field of sterilizing and disinfecting agents, and in particular relates to a solid generating agent and a method for preparing peracetic acid. Background technique [0002] Peracetic acid is a widely used high-efficiency broad-spectrum disinfectant, which has played an important role in the prevention and control of nosocomial infections and outbreaks of large-scale infectious diseases (such as atypical pneumonia). However, traditional peracetic acid exists in liquid form, which not only has poor stability, is not easy to store and transport, but also has risks of explosion and strong corrosion. A solid dosage form of peracetic acid has been developed, which can overcome many shortcomings of liquid preparations. [0003] Chinese patents CN1128257A and CN1542000A disclose the preparation method of peracetic acid solid medicine. According to the method disclosed by the former, the coated tetraacetylethylen...
