DBDCB Chemical Properties,Uses,Production

Chemical Properties

White crystal

Chemical Properties

Light yellow crystalline solid or powder. Commercial products may be soluble concentrate (liquid or solid); pellets/tablets. Mild, acrid, sweet odor.

Definition

ChEBI: An organobromine compound that consists of pentanedinitrile bearing bromo and bromomethyl substituents at position 2.

General Description

Crystals with a pungent odor. Insoluble in water. Used as a preservative in latex paint, adhesives, etc.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

DBDCB 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 Uses

Microbiocide: 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.

Contact allergens

Methyldibromoglutaronitrile is a biocide widely used as a preservative agent in cosmetics, toiletries, and metalworking fluids. It is a potent allerg

Safety Profile

Experimental reproductive effects. When heated to decomposition it emits toxic fumes of NO, and Br-.

Potential Exposure

Nitrile 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.

First aid

Move victim to fresh air. Call 911 or emergency medical service. Administer oxygen if breathing is difficult. If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 min- utes, occasionally lifting upper and lower lids. Seek medi- cal attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions) if breathing has stopped, and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Use amyl nitrate capsules if symptoms develop. All area employees should be trained regularly in emergency measures for cyanide poisoning and in CPR. A cyanide antidote kit should be kept in the imme- diate work area and must be rapidly available. Kit ingredi- ents should be replaced every 1 2 years to ensure freshness. Persons trained in the use of this kit, oxygen use, and CPR must be quickly available. Give artificial respira- tion if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately lush skin or eyes with running water for at least 20 min- utes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion, or skin contact) to sub- stance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmo- nary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.

Shipping

UN3261 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.

Incompatibilities

Corrosive. 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 Disposal

Recycle 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 .
