Dibromonitrilopropionamide (alias dibromocyanoacetamide, DBNPA for short) is a fast-acting, non-oxiziding biocide. It's easily hydrolyzes under both acidic and alkaline conditions.
DBNPA is a new and efficient bactericidal algaecide and water treatment agent. It is preferred for its instability in water as it quickly kills and then quickly degrades to form a number of products, depending on the conditions, including ammonia, bromide ions, dibromoacetonitrile, and dibromoacetic acid. DBNPA acts similar to the typical halogen biocides. 
Properties:
Melting point of 125℃, it can soluble in common organic solvents (such as acetone, benzene, dimethylformamide, ethanol, polyethylene glycol, etc. Slightly soluble in water (25 ℃, 100g water dissolved 1.5g). Its aqueous solution is more stable under acidic conditions, and easy hydrolysis in alkaline conditions. Increasing the pH value, heating with ultraviolet light or fluorescent light, can make its dissolution rate greatly accelerated. Easy to be reductant.
DBNPA has the following features and advantages.
(1) Broad-spectrum bactericidal performance The substance has strong bactericidal power and broad-spectrum antibacterial properties. Both bacteria and fungi have a good killing effect and can be applied to the sterilization of various environments and materials. Especially in water treatment systems, the effect is better and the effect is lasting.
(2) Excellent environmental performance After the substance is used, it is easily degraded. Therefore, after use, there is no residue and no residual toxicity, and there is no pollution to the environment. It meets the requirements of green production and environmental protection and is an ideal environmentally friendly fungicide.
(3) One-time multi-effect composite function This material not only has high-efficiency bactericidal effect, but also has strong functions of algae killing, killing and descaling. In addition, the substance has very little corrosion to equipment and has corrosion inhibition ability. It is a typical multi-effect agent that meets the development trend of fungicides and water treatment agents.
(4) Good synergistic performance The substance and other chlorine-containing fungicides form a compounding agent, which has a good synergistic effect, can improve the effect of other chlorine-containing bactericides, and can reduce the corrosion rate of the chlorine-containing bactericide to the equipment.
