Nickel chloride

 

Chloride Nickel (II) NiCl2. Shiny Golden yellow rhombohedral crystals melting point=1001°C, boiling point=1627°C, the density is 3.53 g/cm3 (anhydrous). Soluble in water, alcohol, ether. Is transformed into NiO by calcination in air or in oxygen. Is reduced by hydrogen when heated. Molar the conductivity at infinite dilution at 25 °C is equal 260,7 Cm•cm2/mol. Get the action of chlorine on heated to 600-800°C Nickel, dehydration of crystalline hydrates of NiCl2•пН2О (n=1, 2, 4, 6, 7).

Used in electroplating; as a catalyst-carrier of the chlorine with the participation of Hcl or Cl2. It turns out at combustion of powder Ni in the current Сl2. Physical properties. Golden-yellow hygroscopic crystals. Wash. at 970°; tight. To 3.55 g/cm3 (anhydrous); solution in water and 59.5 g/100 g (10), Forms a series of crystalline hydrates.

Chloride Nickel hexahydrate - is a monoclinic crystal grass-green, weathered in dry air. Soluble in water, ethanol, in an aqueous solution of ammonia in diethyl ether. In the humid air blurry and green due to the formation of crystalline. The salts of Nickel there is an admixture of ions of iron and cobalt. With alkaline and other chlorides it forms double salts (corniculate).

Anhydrous NiCl2 - brilliant Golden yellow rhombohedral crystals, hygroscopic. Get the action of chlorine on heated to 600-800° C Nickel, dehydration crystalline hydrates of NiCl2•пН2О (n=1, 2, 4, 6, 7).

Density: To 3.55 g/cm3. Boiling point - sublimation at 973° C.

Nickel chloride (II) (or Nickel (II) chloride) is an organic salt of II valent Nickel and hydrochloric acid, chemical formula NiCl2. Anhydrous chloride of Nickel yellow, but a commercial product, which is produced in the form of hexahydrate NiCl2•6H2O, is green. The chlorides of Nickel is a solid crystalline substance, hygroscopic, absorb moisture from the air.

Solutions Nickel (II) chloride are quite acidic, with a pH of about 4.

Most often chloride of Nickel is produced from residues obtained during roasting of Nickel ore.

Heating the hexahydrate in the range 66-133 °C leads to the formation of yellowish dihydrate, NiCl2•2H2O. Anhydrous form by simple heating cannot be obtained, it get by heating in thionyl chloride or by heating in a stream gaseous hydrogen chloride.

In General, Nickel (II) chloride in various forms is the most important source of Nickel for chemical synthesis.

Examples the use of Nickel chloride and its hydrates in organic synthesis is the following:

• for regioselective isomerization dienes;

• for the synthesis of allyl alcohols;

• for the selective synthesis of alkanes from alkenes;

• as a catalyst for the synthesis of dialkylated arylphosphonate.

 

Chloride Nickel is also used for Nickel plating of various metal products.

Upon contact with skin this reagent causes irritation, possible burns, especially if skin is wet. May cause irritation of the respiratory and digestive tract if inhaled. Could potentially cause cancer based on studies on animals. Toxic. Harmful if swallowed.

Nickel chloride(II) 6-water belongs to the 1st class of hazard. The maximum allowable the concentration in the air of the working zone of production areas in the form sea spray aerosol composition (in recalculation on Nickel) - 0,005 mg/m3. With increasing concentrations can cause acute and chronic poisoning with defeat the vital organs and systems, and cause irritation of the skin with development hypersensitivity to the drug (dermatitis).

When working with the drug should to apply individual means of protection (respirators, sewn glasses, rubber gloves) and personal hygiene and to prevent direct contact of the preparation with skin and ingested.

The premises where works are conducted with the drug should be equipped shared supply and exhaust mechanical ventilation.

Chloride Nickel is transported by all modes of transport in accordance with transport regulations cargoes effective for this transport. Chloride of Nickel stored in packages manufacturer in closed ventilated warehouse.
