DBDCB Usage And Synthesis
- Description1,2-Dibromo-2,4-dicyanobutane is the main sensitizer of Euxyl K400, a widely used preservative agent in cosmetics, toiletries or metalwork fluids.
- Chemical PropertiesWhite crystal
- Chemical PropertiesLight yellow crystalline solid or powder. Commercial products may be soluble concentrate (liquid or solid); pellets/tablets. Mild, acrid, sweet odor.
- Uses1,2-Dibromo-2,4-dicyanobutane is a preservative for metalworking fluids, cosmetics, adhesives, latex emulsions and paints, dispersed pigments and detergents; active ingredient in Euxyl K 400 and Tektamer 38.
- DefinitionChEBI: An organobromine compound that consists of pentanedinitrile bearing bromo and bromomethyl substituents at position 2.
- General DescriptionCrystals with a pungent odor. Insoluble in water. Used as a preservative in latex paint, adhesives, etc.
- Air & Water ReactionsInsoluble in water.
- Reactivity ProfileDBDCB may polymerize in the presence of metals and some metal compounds. Incompatible with acids; mixing nitriles with strong oxidizing acids can lead to extremely violent reactions. Nitriles are generally incompatible with other oxidizing agents such as peroxides and epoxides. The combination of bases and nitriles can produce hydrogen cyanide. Nitriles are hydrolyzed in both aqueous acid and base to give carboxylic acids (or salts of carboxylic acids). These reactions generate heat. Peroxides convert nitriles to amides. Nitriles can react vigorously with reducing agents.
- Agricultural UsesMicrobiocide: Tolerances have been established by the U.S. Food and Drug Administration when this substances is used as a preservative in food-grade adhesives and as a slimicide in the manufacture of food-grade paper and paperboard. Used to control slime-forming bacteria and fungi in recirculating water cooling system; oil-recovery drilling mud systems; paper mill and pulp mill water systems and similar industrial processing and chemical systems.

- Potential ExposureNitrile microbiocide used as a preser- vative in food grade adhesives and as a slimicide in the manufacture of food grade paper and paperboard; used to control slime-forming bacteria and fungi in recirculating water cooling system; oil recovery drilling mud systems; paper mill and pulp mill water systems and similar indus- trial processing and chemical systems.
- ShippingUN3261 Corrosive solid, acidic, organic, n.o.s., Hazard class: 8; Labels: 8-Corrosive material, Technical Name Required. UN3439 Nitriles, solid, toxic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.
- IncompatibilitiesCorrosive. Strong oxidizers and reducing agents, strong acids and bases. Reacts with acids, steam, warm water producing toxic and flammable hydrogen cya- nide fumes. Hydrogen cyanide is produced when propioni- trile is heated to decomposition. Nitriles may polymerize in the presence of metals and some metal compounds. They are incompatible with acids; mixing nitriles with strong oxidizing acids can lead to extremely violent reactions. Nitriles are generally incompatible with other oxidizing agents such as peroxides and epoxides. The combination of bases and nitriles can produce hydrogen cyanide. Nitriles are hydrolyzed in both aqueous acid and base to give car- boxylic acids (or salts of carboxylic acids). These reactions generate heat. Peroxides convert nitriles to amides. Nitriles can react vigorously with reducing agents. Acetonitrile and propionitrile are soluble in water, but nitriles higher than propionitrile have low aqueous solubility. They are also insoluble in aqueous acids .
- Waste DisposalRecycle any unused portion of the material for its approved use or return it to the manu- facturer or supplier. Ultimate disposal of the chemical must consider: the material’s impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations .
