Characteristics of DBNPA (Dibromonitrilopropionamide)

Dibromonitrilopropionamide (alias dibromocyanoacetamide, DBNPA for short) is a fast-acting, non-oxiziding biocide. DBNPA is a new and efficient bactericidal algaecide and water treatment agent. It acts similar to the typical halogen biocides.

Product Name

DBNPA Biocide

Chemical Name

2,2-Dibromo-3-nitrilo-propionamide; Dibromocyanoacetamide;



Active content:

99% min; Water: 0.5% max or 2.0% max;

DBNPA is white powder, with 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 powder

DBNPA has features and advantages as below:

1) 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.

2) 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.

3) 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.

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.

The DBNPA biocide has the advantages of high-efficiency broad spectrum, easy degradation, no residual residue, no pollution to the environment, and at the same time, it has a multi-effect function such as sterilization and algae killing, killing and descaling and corrosion inhibition. Widely used in paper mill pulp and circulating cooling water systems. Used to prevent the growth of bacteria and algae in papermaking, industrial circulating cooling water, metalworking lubricants, pulp, wood, paints and plywood, as well as slime control agents.
