Peracetic acid in single-ingredient disinfection solution and preparation method thereof

Abstract

The invention discloses a peracetic acid in single-ingredient disinfection solution and a preparation method thereof, aims to provide a peracetic acid disinfection solution which is low in causticity and high in stability, and adopts the technical key points that the disinfection solution comprises the following components in percent by weight: 25-35% of hydrogen peroxide, 25-35% of acetic acid, 0.01-1.5% of HWP integrated coordination stable system based on a polyhydric and polycarboxylic multi-ligand structure compound, 0.01-1.5% of special block nonionic surface active agent, and the balance of water. The preparation method comprises the following steps: 1), compounding an HWP integrated coordination stable system compound; 2), weighting the raw material according to the weight ratio required by claim 1; and 3), filling water, hydrogen peroxide, the HWP integrated coordination stable system, and the special block nonionic surface active agent in a reactor sequentially, stirring, dissolving, filling the acetic acid is filled in the reactor lastly and stirring for 30-45 minutes to obtain the disinfection solution. The invention belongs to the field of preparation of chemical disinfectants.

Description

technical field [0001] The invention discloses a disinfectant solution, specifically a monobasic peracetic acid disinfectant solution, which belongs to the field of chemical disinfectant preparation. Background technique [0002] Domestic and foreign studies have shown that peracetic acid (PAA) is a high-efficiency broad-spectrum chemical disinfectant. It has the advantages of low use concentration, strong bactericidal effect, short disinfection time, and non-toxic decomposition products. It still has a strong bactericidal effect at a low temperature of minus 20-40°C. It is currently an ideal high-efficiency, environmentally friendly, and non-toxic disinfectant. . However, due to the poor stability of peracetic acid, factors such as temperature, light, organic matter, alkali, and various metal ions can rapidly reduce the effective concentration of peracetic acid. Since the 1970s, how to improve the stability of peracetic acid in peracetic acid disinfectants has always been...

AI Technical Summary

Problems solved by technology

However, its stability can generally only be guaranteed for about one month, which cannot meet the objective needs of the market.

Due to the above problems, domestic peracetic acid is usually packaged in binary form. Binary peracetic acid has an unstable effective peracetic acid content and is very corrosive (contains about 3% sulfuric acid). It is inconvenient to use and must be activated on the same day. There are many inconveniences after use, and it is generally only used on a small scale by medical institutions.

The research on monobasic peracetic acid can solve the problems existing in binary finished products, but the stability of monobasic peracetic acid has always been a big technical problem

[0005] The above patents have their own characteristics in improving the concentration or stability of peracetic acid. Most of the production techniques are complicated, and rectification tower rectification or ion exchange resin must be used, and the production cost is high; or it is necessary to add sulfuric acid or heterocyclic compounds (such as 8- hydroxyquinoline, dipicolinic acid) and there are food safety hazards

Its overall stability or security still does not meet production requirements
