Property:
DBNPA is white crystals, mp. 125& ordm, C, soluble in actone. Polyethyleneglycol, benzen, ethanol and the like. It' s stable in acidic conditions, and decomposed in alkaline conditions or in the presence of hydrogen sulphide. It' s an efficient germicide for recycling water system, can Penetrate in the cytocyst of microbes quikly and kill them by reacting with some Proteins in it, Stopping the Redox of cells.
DBNPA has a good stripping properties, little poison, and no foam in system. The organic solutions can miscible with water.
Specifications:
Assay: 99% min
Melting Point: 122-128 C
PH( 1% aqueous solution) : 4.0-6.5
Loss on drying: 1% max
Usage:
Biocides in broad spectrum. It is widely used in industrial circulating water system, large air-condition and the large center of sewage treatment to eliminate microorganism and alga and shuck off clay. It is also used in the process of paper making to prevent reducing quality of paper by generation of microorganism. It is suitable for metal cutting of cooling liquor, recovery system of oil, latex and ply-woods as anti-spy biocides. It has 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 efficacy against in bio-films and against a broad spectrum of bacteria, fungus and yeasts. Coating and Fillers
DBNPA series products are used in the short-term preservation of 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

2-BROMO-2-NITRO-1, 3-PROPANEDIOL ( BRONOPOL)

CAS No.: 52-51-7 Molecular Formula: C3H6BrNO4
Molecular Weight: 199.99
Synomas: BRONOPOL, 2-Bromo-2-Nitro-1, 3-Propanediol, Bronopol, BNP
Property:
Appearance - Bronopol is supplied as crystals or crystalline powder, which may vary from white to pale yellow in colour depending on the grade of material being offered.
Melting Point - As a pure material, Bronopol has a melting point of about 130& ordm, C. However due to its polymorphic characteristics, Bronopol undergoes a lattice rearrangement at 100 to 105& ordm, C and this can often be wrongly interpreted as the melting point.
At temperatures above 140& ordm, C Bronopol will decompose exothermically releasing Hydrogen bromide and oxides of Nitrogen.
Solubility - Bronopol is readily soluble in water although the dissolution process is endothermic. Solutions containing up to 28% w/ v are possible at ambient temperature.
Bronopol is poorly soluble in non-polar solvents but shows a high affinity for polar organic solvents.
Specifications:
Characteristics: White or almost white crystalline powder
