NICKEL BROMATE Chemical Properties,Usage,Production

Description

Nickel bromide (chemical formula: NiBr2) is the nickel salt of hydrobromic acid. It is a weak reducing agent made by the reaction of nickel, nickel oxide, nickel carbonate or nickel hydroxide with hydrobromic acid, or the reaction between nickel and bromine. Nickel bromide has many kinds of applications. It is mostly an electron acceptor, being capable of catalyze organic structure such as carbonamides, and convert aryl bromides into aryl phosphines. It can also be used as a catalyst in cross-coupling reactions. It is also applied for bonding to other ligands. For example, graphene supported NrBr2 is used in a condensation reaction consisting of aromatic aldehyde, acetoacetate and urea for manufacturing 3, 4- dihydropyrimidiones.

Chemical Properties

Brownish powder

Uses

Nickel(II) Bromide, is used as a source of bromide ion. It is also an important raw material used in various chemical synthesis and also as a catalyst in cross-coupling reactions.

General Description

Yellowish-green odorless solid. Sinks in and mixes with water.

Air & Water Reactions

Deliquescent. Soluble in water.

Reactivity Profile

NICKEL BROMATE is a yellow, crystalline material, mildly toxic, carcinogenic. On contact with strong acids or acid fumes NICKEL BROMATE produces highly toxic and corrosive hydrogen bromide gas. When heated to decomposition NICKEL BROMATE emits toxic bromide fumes. [M. K.]

Health Hazard

Inhalation of dust causes irritation of nose and throat. Ingestion causes vomiting; if large amount is swallowed and not thrown up, it can cause drowsiness and other symptoms of bromide poisoning. Dust irritates eyes and may cause dermatitis in contact with skin.

Fire Hazard

Special Hazards of Combustion Products: Irritating hydrogen bromide vapors may form in fire.

Purification Methods

Crystallise it from dilute HBr (0.5mL/g) by partial evaporation in a desiccator. The anhydrous salt is yellow, but the trihydrate is green.
