Low-corrosion peracetic acid solid generating agent as well as preparation method and application thereof

Abstract

The invention discloses a peracetic acid solid generating agent as well as a preparation method and an application thereof. The peracetic acid solid generating agent consists of tetra acetyl ethylene diamine, anion active agents and antiseptic agents. A reagent kit used for preparing the peracetic acid consists of peracetic acid solid generating agents and sodium percarbonate. The mol ratio of tetra acetyl ethylene diamine to sodium percarbonate to anion active agents to antiseptic agents is 1 / (0.5 to 2) / (0.2 to 0.5) / (0 to 0.5). The peracetic acid solid generating agent can accelerate the preparation speed of the peracetic acid and is favorable for maintaining effective ingredients of solution, and simultaneously, the washing and cleaning effect of the solution can also be enhanced. The antiseptic agents are added into the system, the corrosion effect of the peracetic acid on various kinds of metals can be reduced, and the stability of the solution is enhanced.

Description

technical field [0001] The invention relates to a low-corrosion peracetic acid solid generating agent and its preparation method and application. 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, avian influenza, and H1N1 influenza). effect. However, traditional peracetic acid exists in liquid form, which not only has poor stability and is not easy to store, but also has many explicit and hidden risks such as explosion and strong corrosion. A solid dosage form of peracetic acid has been developed, which can overcome many deficiencies of liquid peracetic acid. The performance of its solid raw material is relatively stable, it can be stored for a long time, and it can be prepared and used when needed, so that the new type of peracetic acid has new advant...

AI Technical Summary

Problems solved by technology

According to the method disclosed by the former, the film-coated N, N, N'N'-tetraacetylethylenediamine (TAED) and the film-coated sodium perborate are mixed in a certain molar ratio, and then Dissolve the mixed solid in a certain amount of normal temperature water to produce peracetic acid. Although the problems of inconvenient storage, transportation and use are solved, the solubility is poor, the reaction for preparing peracetic acid is slow, and the active ingredients are volatilized and reduced. and other problems; and the disclosed method of the latter is composed of N-acetyl activator, inorganic peroxide and surfactant, although the preparation speed of peracetic acid has been accelerated, it still does not solve the problem of poor stability and corrosion of peracetic acid. high sex problem
