Description

Chlorine dioxide disinfectant and preparation method and application thereof
Technical Field
The invention belongs to the technical field of disinfectants, and particularly relates to a chlorine dioxide disinfectant, and a preparation method and application thereof.
Background
The information in this background section is only for enhancement of understanding of the general background of the invention and is not necessarily to be construed as an admission or any form of suggestion that this information forms the prior art that is already known to a person of ordinary skill in the art.
Chlorine dioxide is a strong oxidant, has high-efficiency and broad-spectrum bactericidal effect, does not generate drug resistance, and is classified as A1-grade safe disinfectant by the United nations World Health Organization (WHO). The disinfectant is widely applied to medical treatment and health, object surface, environmental air disinfection, drinking water disinfection, food processing disinfection, food preservation and other application places, and is also widely applied to the field of water treatment.
The current preparation methods of chlorine dioxide disinfectants are reported more. According to the research of the inventor, the activating agent of the existing chlorine dioxide disinfectant is generally hydrochloric acid, but the hydrochloric acid has high volatility and serious corrosiveness, is easy to cause the disinfectant to lose efficacy and pollutes the environment. Therefore, research relates to a solid chlorine dioxide slow release agent and a preparation method thereof (Chinese patent CN111493069A), and the solid chlorine dioxide slow release agent comprises the following components, by weight, 20-35 parts of a chlorine dioxide precursor, 10-15 parts of a modified carbon nano tube, 10-15 parts of an adsorbent, 15-25 parts of a stabilizer, 15-25 parts of a water-soluble adhesive and 10-15 parts of a water-insoluble filler. In addition, the research relates to a preparation method of chlorine dioxide effervescent tablets (Chinese patent CN 107439541A), which is prepared from the following raw material medicines in parts by weight: 10-50 parts of stable chlorine dioxide, 10-50 parts of citric acid, 10-50 parts of sodium carbonate, 01-10 parts of PEG600, 1-10 parts of vaseline, 1-10 parts of white oil, 0-1 part of pigment and 1-10 parts of sophora flavescens extract.
It can be seen that, in order to avoid the defect of using hydrochloric acid as an activating agent, other kinds of activating agents (such as citric acid and the like) have been adopted at present, but the inventor researches and discovers that the activating efficiency of the existing activating agent replacing hydrochloric acid is low, so that it is necessary to develop a new chlorine dioxide disinfectant, improve the activating efficiency of chlorine dioxide, enrich the kinds of the disinfectant, make the production cost of the disinfectant lower and the production process simpler, and meet the application requirements of market users.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a chlorine dioxide disinfectant and a preparation method thereof, wherein the chlorine dioxide disinfectant has low production cost and simple production process.
In order to achieve the technical purpose, the invention adopts the following technical scheme:
in a first aspect of the invention, there is provided the use of 2-acrylamido-2-methylpropanesulfonic acid (abbreviated as AMPS) as an activator for chlorine dioxide disinfectants.
AMPS is generally used as a polymer monomer, a modifier, and a stabilizer in the field of oil fields and water treatment, and even if it is expanded to other fields, it only utilizes its properties of polymerization, modification, and stabilization. However, the invention has been found through experiments unexpectedly that AMPS can replace hydrochloric acid and citric acid as the activator of the chlorine dioxide disinfectant. AMPS contains a sulfonic acid group, which is different from a conventional organic acid such as citric acid in nature, and not all of the organic acid can be used as an activator of chlorine dioxide disinfectant (for example, malonic acid cannot be used as an activator of chlorine dioxide disinfectant), and at the same time, contains an amide group which affects the acidity of the sulfonic acid group, so that, theoretically, even though AMPS can be used as an activator, the activation effect should be weaker than that of hydrochloric acid, and similar to citric acid, even though the activation effect is worse than that of citric acid due to the influence of the amide group. However, experiments show that AMPS is adopted as the activating agent of the chlorine dioxide disinfectant, the activating effect is better than that of polybasic organic acids such as citric acid, malonic acid and the like, and the activating effect is even similar to that of hydrochloric acid.
In a second aspect of the present invention, there is provided a chlorine dioxide disinfectant comprising: a main agent and an activating agent;
the main agent is sodium chlorite aqueous solution or stable chlorine dioxide solution;
the activating agent is 2-acrylamide-2-methylpropanesulfonic acid solid.
The invention develops a novel chlorine dioxide disinfectant, enriches the types of the disinfectant, has lower production cost and simpler production process, and meets the application requirements of the market.
In a third aspect of the present invention, there is provided a method for preparing the chlorine dioxide disinfectant, comprising:
and (3) uniformly mixing the main agent and the activating agent at room temperature, and carrying out an activation reaction to obtain the catalyst.
In a fourth aspect of the invention, there is provided the use of a chlorine dioxide disinfectant as described above in medical hygiene disinfection, in disinfection of surfaces of objects, in disinfection of ambient air or in disinfection of food processing.

(1) the chlorine dioxide disinfectant prepared by the invention has good use performance, and can be widely applied to the fields of medical treatment and health, object surface and ambient air disinfection, food processing disinfection, food preservation and the like.
(2) The chlorine dioxide disinfectant has the advantages of cheap production raw materials, wide sources and low production cost of chlorine dioxide.
(3) The activation efficiency using 2-acrylamido-2-methylpropanesulfonic acid was high, as shown in example 1 in comparison with comparative examples 1 and 4. The activation efficiency with 2-acrylamide-2-methylpropanesulfonic acid is higher than that with citric acid or malonic acid. In addition, the slow release effect (namely after being placed for 7 days) of the chlorine dioxide by adopting the 2-acrylamide-2-methylpropanesulfonic acid is better than that of the chlorine dioxide by adopting hydrochloric acid, and the corrosion inhibition effect on metals is also better.
(4) After activation, 2-acrylamido-2-methylpropanesulfonic acid (C)7H13NSO4) Conversion to sodium 2-acrylamido-2-methylpropanesulfonate (C)7H12NSO4Na)。
(5) Compared with the activator adopting liquid hydrochloric acid, the activator AMPS is solid, and is easy to produce, package and transport.
(6) The method is simple, convenient to operate, high in practicability and easy to popularize.

And (4) conclusion: based on the above examples and comparative examples, chlorine dioxide disinfectant can be prepared only by reasonable selection of reaction raw materials and control of reaction conditions. In the invention, a specific raw material, namely sodium chlorite (or stable chlorine dioxide solution), is selected to be mixed with 2-acrylamide-2-methylpropanesulfonic acid for activation reaction to obtain the chlorine dioxide disinfectant, and in the experimental research process, the inventor surprisingly discovers that the 2-acrylamide-2-methylpropanesulfonic acid can be used for preparing the chlorine dioxide disinfectant. The activation efficiency of 2-acrylamide-2-methyl propanesulfonic acid is the same as that of hydrochloric acid, and is much higher than that of citric acid or malonic acid. And malonic acid also does not produce a useable chlorine dioxide disinfectant.
Experimental example 1

The weight loss method is to determine the corrosion rate according to the weight change of the material before and after corrosion, and the average corrosion rate is represented by the weight loss in unit area in unit time in the experimental example.
The experimental results show that:
the chlorine dioxide disinfectant prepared by adopting 2-acrylamide-2-methylpropanesulfonic acid has better corrosion inhibition effect on metals than the chlorine dioxide disinfectant prepared by adopting hydrochloric acid.
