Organcide DBNPA

Description

CASE: 10222-01-2

NAMES: DBNPA organicide, DBNPA, 2,2-dibromo-3-nitrilopropionamide, 2,2-dibromo-2-cyanoacetamide

SOLVENT: Water

ACTIVE INGREDIENT CONCENTRATION: 20%

ADVANTAGES It is a fast-acting, broad-spectrum, low-residue, biodegradable biocide that:
> eliminates a broad spectrum of microorganisms (bacteria, fungi, and algae)
> reduces production stoppages and delays
> is more environmentally friendly because it is biodegradable and rapidly breaks down into non-hazardous compounds.
> is easy to handle
> under normal conditions of use, does not pose significant risks to human health or the environment
> is stable under normal conditions of use but should not be used at temperatures above 70°C or with strong reducing agents
> has acceptable transport, storage, stability, and handling characteristics

USES
It has a wide range of uses:
> in the paper industry as a preservative in paper coating and slurries
> for sludge control on paper machines
> in hydraulic fracturing wells
> in cooling water systems, evaporative condensers and heat exchangers
> in air washing systems
> for reverse osmosis membranes
> as a preservative for paints, coatings and industrial adhesives

DISADVANTAGES
> It is a hazardous material to be handled with care, especially in concentrated form.
> It must not be used at temperatures above 70°C.
> It is inactivated by strong reducing agents, mercaptobenzothiazole, ammonia and hydrogen sulfide.

ACTION MODE
DBNPA is a fast-acting biocide which exerts its biocidal action directly after application, acting via bromine which inactivates enzymes by converting -SH functional groups into the oxidized S-S form.
DBNPA's easy reaction with sulfur nucleophiles common to micro-organisms, such as glutathione or cysteine, is the basis of its antimicrobial mode of action. DBNPA reacts via its bromine chemistry, i.e. via bromine which inactivates amino acids and thiol-based enzymes (R-SH) by converting their -SH functional groups into oxidized S-S form and forming disulfide bridges:
This reaction irreversibly disrupts the function of cell surface components, interrupting transport across cell membranes and inhibiting key biological functions.
DBNPA acts in a similar way to typical halogenated biocides.

RECOMMENDED DOSAGES (DBNPA at 20%)
> Bacteria – 90 to 420 ppm
> Fungi and algae – 480 to 1500 ppm
> Continuous feeding – 12 to 36 ppm

DEGRADATION
DBNPA is a biocidal organic compound which degrades readily (hydrolysis) in both acidic and basic aqueous media.
It hydrolyzes rapidly to form a number of products, depending on conditions, including ammonia, bromides, dibromoacetonitrile and dibromoacetic acid.
