Embodiment

[0026] A disinfectant containing 2,2-dibromo-3 cyanopropionamide, comprising the 2,2-dibromo-3 cyanopropionamide composition of the following components

[0027] Component Content (WT%)

[0028] 2,2-Dibromo-3 cyanopropionamide 23-70

[0029] Cyanoacetamide 20-67

[0030] Disintegrant 5-15

[0031] Sodium sulfate 5-15.

[0032] The disintegrant consists of sodium bicarbonate, citric acid, and sodium carboxymethylcellulose;

[0033] The 2,2-dibromo-3 cyanopropionamide composition also contains an appropriate amount of povidone, sodium lauryl sulfate, magnesium stearate, and sodium benzoate, and each of the added ingredients generally accounts for 1% of the composition. %.

Abstract

A composite disinfectant contains 2,2-dibromo-tricyano propanamide, cyanoethanamide and disintegrant proportionally. Its advantages are high solubility and dissolving speed in water, broad spectrum, high effect, safety and stability, and low poison.

Description

technical field [0001] The invention relates to a water-soluble halogen-containing disinfectant. Background technique [0002] 2,2-Dibromo-3-cyanide (cyanide can also be translated as nitrile) propionamide (DBNPA), English name: 2,2-Dibromo-3-Nitrilopropion Amide, structural formula: Molecular weight: 242, appearance: white crystalline powder, effective content ≥ 98%, melting point (MP): 122°C-125°C, pH value 4.0-6.5, mainly used for water treatment, paper pulp, and pharmaceutical intermediates, 2 , 2-dibromo-3 cyanopropionamide is soluble in organic solvents, which can release activated effective bromine in a slow manner and play a bactericidal effect. It can be used as a bromine-releasing disinfectant with high effective bromine content, no pungent odor, and stable It has many advantages, such as good antibacterial effect, strong bactericidal effect, and no irritation to skin and mucous membranes. Because it is basically insoluble in water and cannot exert its bacterici...
