2 2-dibromo-3-nitrilo-propionamide (DBNPA)

CAS No.: 10222-01-2
Molecular Formula: C3H2ON2Br2
Molecular Weight: 241.84

Structural Formula:

Properties:

2 2-dibromo-3-nitrilo-propionamide (DBNPA) is white crystals. The melting point is 125°C. It can soluble in acetone, polyethylene glycol, benzene, ethanol and the like. DBNPA is stable in acidic conditions and decomposed in alkaline conditions or in the presence of hydrogen sulfide. DBNPA is an efficient germicide for recycling water system.

DBNPA can penetrate in the cytocyst of microbes quickly. And then kill them by reacting with some proteins in it. In this way, it can stop the redox of cells. It has a good stripping property, little poison, and no foam in the system. The organic solutions can miscible with water.

Usage:

Biocides are in a broad spectrum. DBNPA is widely used in the industrial circulating water system, large air-condition and the large center of sewage treatment. It is used to eliminate microorganism and alga and shuck off clay. DBNPA is also used in the process of papermaking to prevent reducing the quality of paper by a generation of microorganism.

It is suitable for metal cutting of cooling liquor, recovery system of oil, latex, and ply-woods as anti-spy biocides. DBNPA has the following advantages.

  1. Easy to handle.
  2. No unusual oxidation hazards.
  3. Similar performance and safety in paper and oilfield applications.
  4. Slime control in the wet-end of the paper mill and performs exceptionally well against slime-forming bacteria.

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

Additionally, DBNPA series products are used in the short-term preservation of coatings and coating additives. Such as latex, starch and mineral slurries. It is a quick-kill biocide that is broad-spectrum and does not contain or release formaldehyde.

Package and Storage:

25 kg fiber drum. Keep dry.
