Problems solved by technology

[0003] Although dibromohydantoin has many advantages as above, the solubility of dibromohydantoin in water is very low, the dissolution rate is relatively slow, and the stability after being dissolved in water is very poor, so the application of dibromohydantoin is now subject to very large limit
However, the solubility of dibromohydantoin in this invention is still very small, and the solid disinfectant will have dust hazards during use, which will threaten the health of disinfection operators
In addition, it involves solubilizers, disintegrants and other additives, the process is relatively cumbersome and the cost will be high
CN10123142.8 has made the aqueous disinfectant of dibromohydantoin by adding solubilizer, synergist, stabilizer and water, but the dibromohydantoin disinfectant produced by this method has poor stability and cannot meet the requirements of real-world conditions at all. production needs

Embodiment Construction

[0018] The present invention will be further described below in conjunction with specific examples.

[0019] The chemical name of dibromohydantoin of the present invention is 1,3-dibromo-5,5-dimethylhydantoin, referred to as: DBDMH, and its molecular formula is C 5 h 6 o 2 N 2 Br 2 , Dibromohydantin is light yellow crystalline powder, slightly soluble in water, soluble in chloroform, ethanol and other organic solvents, stable when dry, easy to decompose in strong acid or strong alkali, can be further processed into granules and tablets, and its disinfection is the most effective The optimal pH value is 5-7, and the residue after disinfection can be biodegraded in a short time without any pollution to the environment. Dibromohydantoin can continuously release Br in water - ions to form hypobromous acid, the reaction formula is: C 5 h 6 o 2 N 2 Br 2 +2H 2 O→C 5 h 8 N 2 o 2 +2HOBr. Hypobromous acid can oxidize and decompose the microcystins produced after the deat...

Abstract

The invention relates to high-concentration high-stability dibromohydantoin disinfectant. The high-concentration high-stability dibromohydantoin disinfectant comprises the following components in part by weight: 1 to 20 parts of dibromohydantoin, 0.1 to 10 parts of cosolvent, 1 to 10 parts of stabilizing agent, 0.1 to 2 parts of synergistic agent, 1 to 5 parts of pH regulating agent and 50 to 90 parts of water. The high-concentration high-stability dibromohydantoin disinfectant is prepared by the following steps of: dissolving the cosolvent into water; adding dibromohydantoin to mix; adding the stabilizing agent, the synergistic agent and the pH regulating agent; and mixing uniformly to obtain the dibromohydantoin disinfectant. The high-concentration high-stability dibromohydantoin disinfectant solves the problem of dissolution of the dibromohydantoin, provides conditions for sterilization in various places, has the stability more excellent than the using effect of the like disinfectant in the conventional market, and can wet the surface of microorganisms so as to achieve the synergistic effect.

Description

technical field [0001] The invention relates to a disinfectant solution, in particular to a high-concentration and high-stability dibromohydantoin disinfectant solution. Background technique [0002] Dibromohydantoin is a new type of release disinfectant, which has a good bactericidal effect because it can release active ingredients. The available bromine in dibromohydantoin is the main component for killing microorganisms. In aqueous solution, dibromohydantoin can react with water to generate hypobromous acid and free bromine. Hypobromous acid and free bromine have strong oxidizing properties, which can oxidize and decompose the biological enzymes in microorganisms to make them invalid, thereby achieving the effect of eliminating microorganisms. Hypobromous acid and free bromine can also react with nitrogen-containing compounds to form ammonium bromide, which still has a certain bactericidal effect. As a carrier, 5,5-dimethylhydantoin can be decomposed into nitrogen and c...
