2 2-Dibromo-3-Nitrilopropionamide (DBNPA)

CAS No.:

10222-01-2

Molecular Formula:

C₃H₂Br₂N₂O

Molecular Weight:

242

Structure Formula:

Properties:

DBNPA is white crystals, mp.125℃, soluble in acetone, polyethyleneglycol, benzene, ethanol, etc. DBNPA is stable in acidic conditions and decomposed in alkaline conditions or the presence of Hydrogen Sulphide.

DBNPA is an efficient germicide for the recycling water system. DBNPA can penetrate the cytocyst of microbes quickly and kill them by reacting with some proteins, stopping the cells’ Redox.

DBNPA has good stripping properties, little poison, and no foam in the system. However, the organic solutions can be miscible with water.

Specifications:

Uses:

Biocides in a broad spectrum. DBNPA is widely used in industrial circulating water systems, large air-conditioning, and large sewage treatment centers to eliminate microorganisms, algae, and shuck-off clay. DBNPA is also used in the papermaking process to prevent reducing paper quality by generating microorganisms.

DBNPA is suitable for metal cutting of cooling liquor, oil, latex recovery system, and plywood as anti-spy biocides. DBNPA has the following advantages: easy to handle; no unusual oxidation hazards; similar performance and safety in paper and oilfield applications; used for slime control in the wet-end of the paper mill and performs exceptionally well against slime-forming bacteria.

DBNPA has exhibited outstanding efficiency against bio-films and a broad spectrum of bacteria, fungi, and yeasts.

Additionally, DBNPA series products are used to preserve coatings and coating additives such as latex, starch, and mineral slurries. DBNPA is a fast-acting/quick-kill biocide that is broad-spectrum and does not contain or release formaldehyde

Packing and Storage:

25 kg fiber drum, keep dry.
