Introduction of DBNPA
DBNPA stands for 2,2-Dibromo-3-nitrilopropionamide, which is a biocide commonly used for controlling microbial growth in industrial water treatment systems, including cooling towers, paper mills, and oil field operations.
Physical Features of DBNPA
Appearance: It is a white crystalline powder at room temperature, with a pungent smell of mold.
Boiling point：760 mmHg (℃) 221.5
Melting point：(℃) 122-125
Flash point：℃ (closed type)
Density：G/cm3 2.451
Refractive Index：ND25 1.624
Vapor pressure：MmHg (℃)0.107 (25)
Solubility：Dibromocyanoacetamide can be dissolved in acetone, polyethylene glycol, benzene, ethanol, and other organic solvents, and is slightly soluble in water. 100 grams of water can dissolve 1.5 grams of dibromocyanoacetamide at 25°C. Increasing pH, heating, UV light or fluorescent irradiation can increase solubility.
Stability：Its aqueous solution is relatively stable under acidic conditions and easily decomposes under alkaline conditions. When the pH value increases from 6.7 to 9.7, its half-life decreases from 37 hours to 0.11.
It has good inhibitory effect on biological biofilms.
After DBNPA is added to the system, its active components can quickly attack floating microorganisms and quickly sterilize them. At the same time, due to the good permeability of organic bromine, the active components in the agent can quickly penetrate into the surface of the metal. Acts on smaller microbial communities to rapidly depolymerize and prevent biofilm formation. For a system that has formed a biofilm, its active components react with the slime layer in the biofilm, but quickly penetrate deeper into the biofilm, acting on microorganisms at the interface between the biofilm and the surface. The biomass community is destroyed, its stickiness is destroyed, and the biofilm is induced to fall off.
Effectively kill bacteria
DBNPA has a remarkable effect on controlling bacterial flora. 2-5mg/l DBNPA (effective substance) can reduce the number of bacteria in the car group by 5-6log within 3 hours; 2-4mg/l DBNPA (effective substance) can reduce the bacteria in the car group by 6log in 2 hours. For Legionella in the biofilm, 10mg1 DBNPA (effective substance) can completely kill Legionella in 12 hours. Other data show that the combined use of low-dose organobromine and glutaraldehyde can reduce Legionella bacteria in biofilms to undetectable levels.
Rapid degradation
After completing its sterilization effect, DBNPA can quickly degrade into carbon dioxide, ammonia and bromide salts. It will not cause the accumulation of harmful ions in the water body, has no impact on the environment, and allows unrestricted emissions. This is a significant feature that distinguishes organobromine biocides from other non-oxidizing biocides.
Effectively kills sulfate reducing bacteria
Oilfield wastewater has a high sulfate content, which is extremely conducive to the reproduction of sulfate-reducing bacteria. The massive proliferation of sulfate-reducing bacteria leads to an increasing level of HS in water bodies. DBNPA can quickly act on sulfate-reducing bacteria and kill them quickly before they react with sulfate to form Hs.
Applications of DBNPA
DBNPA (2,2-dibromo-3-nitrilopropionamide) is a broad-spectrum and highly efficient industrial bactericide, mainly used to control and inhibit the growth of bacteria and algae in various aqueous and non-aqueous environments. Its application fields are very wide, including but not limited to:
Papermaking industry: Prevent microbial contamination in the pulp and papermaking process.
Industrial circulating cooling water system: Maintain the cleanliness of the cooling water system to prevent the formation of biofilm and the resulting corrosion, decrease in heat exchange efficiency and other problems.
Lubricating oil for metal processing: Protect lubricating oil from microbial degradation and extend its service life.
Wood preservation: Treat wood to prevent damage to wood by decay fungi and other harmful microorganisms.
Paint and plywood industry: Used as an additive to ensure that products are not affected by microorganisms during production and storage.
Membrane filtration system: Used to prevent membrane fouling and maintain stable membrane flux.
- DBNPA is corrosive to metals, so plastics are preferred for storage and metering pumps. This is not as much of a concern at the very low, concentrations used in RO/NF systems.
- DBNPA has minimal toxicology concerns, but the supplier recommends that for potable water systems, the permeate be dumped during slug-dosing. Only offline use of DBNPA is recommended for potable water systems.
- DBNPA is classified as a "weak sensitizer." When handling any chemical, reference the Material Data Safety Sheet for precautions and proper handling and storage.
- Although DBNPA is useful as a disinfectant, it should not be used for storage since it is not long-acting.
