Problems solved by technology

[0005] 3. It has an unpleasant chlorine odor and is irritating to the skin
But when this dibromohydantoin is used alone, its solubility in water is small and the dissolution rate is slow, which greatly restricts its promotion and application

Embodiment 1

[0023] Take by weighing 54 kilograms of sulfamic acid, 39 kilograms of anhydrous sodium carbonate, and 7 kilograms of anhydrous sodium sulfate, and mix uniformly to obtain a composite cosolvent. Then get 50 kilograms of above-mentioned composite auxiliary solvents, 40 kilograms of dibromohydantoin, 5 kilograms of anhydrous sodium carbonate, 5 kilograms of dimethylhydantoin and mix homogeneously, promptly make a kind of bromine-containing disinfectant of the present invention.

Embodiment 2

[0025] Take by weighing 60 kilograms of sulfamic acid, 35 kilograms of anhydrous sodium carbonate, and 5 kilograms of anhydrous sodium sulfate, and mix uniformly to obtain a composite cosolvent. Then get 40 kilograms of above-mentioned composite auxiliary solvents, 30 kilograms of dibromohydantoin, 15 kilograms in anhydrous sodium carbonate, 15 kilograms in dimethylhydantoin and mix homogeneously, promptly make a kind of bromine-containing disinfectant of the present invention.

Embodiment 3

[0027] Weigh 50 kilograms of sulfamic acid, 40 kilograms of anhydrous sodium carbonate, and 10 kilograms of anhydrous sodium sulfate, and mix them uniformly to obtain a composite cosolvent. Then get 30 kilograms of above-mentioned composite auxiliary solvents, 20 kilograms of dibromohydantoin, 25 kilograms in anhydrous sodium carbonate, 25 kilograms in dimethylhydantoin and mix homogeneously, promptly make a kind of bromine-containing disinfectant of the present invention.

Abstract

The invention provides a bromine-containing disinfectant, which is prepared from the following components in percentage by weight: 20 to 60 percent of bromine-containing compounds, 30 to 50 percent of compound cosolvents, 0 to 25 percent of anhydrous sodium carbonate, and 0 to 25 percent of dimethylhydantoin. The bromine-containing disinfectant improves the bioavailability of bromide, wherein the bromine-containing compound has the advantages of high dissolution velocity and strong effects of disinfection and sterilization. The bromine-containing disinfectant is used to prepare thimerosal at a concentration of 250 to 400 ppm to wash and disinfect beer production equipment and pipelines of a beer brewery, can completely kill various bacteria and meets the CRB microbiological standards.

Description

technical field [0001] The invention relates to a disinfectant, in particular to a bromine-containing disinfectant. Background technique [0002] For a long time, chlorine-containing disinfectants have been widely used in the field of disinfectants. The sterilization and disinfection principle of chlorine-containing disinfectants is based on the biocidal effect of hypochlorous acid generated after chlorine-containing disinfectants undergo hydrolysis reactions in water. However, during the long-term use of chlorine-containing disinfectants, the following disadvantages were found: [0003] 1. The pH range of the effective killing of chlorine-containing disinfectants is very narrow, and the lowest dissociation reaction occurs at pH 7.0. When the pH value continues to rise, hypochlorous acid is easily dissociated into hypochlorous acid with extremely poor killing power ion. Because hypochlorite ions have a negative charge, when they are close to microorganisms, they are repell...
