Blue Crystal Printing and Dyeing Industry Nickel Sulfate

Blue Crystal Printing and dyeing industry Nickel sulfate
There are three kinds of water, six water and seven water. Commodities are more than six water content, there are alpha - type and beta - type two variants, the former is blue crystal, the latter for the green - crystalline. When heated to 103 degrees C lost six crystal water. Soluble in water, slightly soluble in ethanol, methanol, its aqueous solution is acidic, slightly soluble in acid, ammonia, toxic. Mainly used in electroplating industry, is the main nickel and nickel and chemical nickel salt, is also the source of nickel ions, can be in the electroplating process, the dissociation of nickel ions and sulfate ions.
Chinese name English name Nickelous sulfate chemical nickel sulfate NiSO4 6H2O relative molecular mass of 262.84 categories of inorganic chemicals - sulfate - nickel salt control does not control the storage environment sealed in cool and dry preservation CAS10101-97-0

Chemical property
The alpha type containing 6 molecules of crystal water is blue and green tetragonal crystal, and is converted into a beta type green transparent crystal at 53 degrees c.. 40 stable at room temperature, room temperature become blue opaque crystal. Green transparent crystal containing 7 parts of crystal water. Have a sweet taste. Slightly weathered. At about 100 C, the 5 molecules are lost to form a water, and the water is a yellow green water at 280 degrees centigrade. Half lethal dose (rat, abdominal) 500mg/kg. Carcinogenic potential. Nickel sulfate has no water, six water, seven water 3 species, mainly six water. 

The anhydrous substance is yellow green crystal, and the relative density is 3.68. Soluble in water, insoluble in ethanol, ether. 31.5 to 53.3 degrees C crystallization of six water nickel sulfate, six water is blue or emerald green fine crystal, the relative density of 2.07. Soluble in water, aqueous solution is acidic. Soluble in concentrated ammonia (nickel ammonia ion), but in organic solvents in a very small (a common problem, the crystal lattice can be too large end). 280 C 840 c lose all crystal water starts to decompose, releasing three sulphur trioxide, into nickel oxide. 

Less than 31.5 DEG C for seven nickel sulfate crystallization water, seven water green transparent orystal, sweet and astringent, slightly easy to weathering, the relative density is 1.948. Melting point 100 ~ 98. Loss of 6 crystalline water at 103. Soluble in water and ethanol, easy deliquescence. Nickel sulfate is exposed to dust and organic matter, which can sometimes cause combustion or explosion. Toxic, the highest allowable concentration of air in the air 0.5mg/m3.

Function and Application
1.Mainly used in electroplating industry, is the main nickel and nickel and chemical nickel salt, is also the source of nickel ions, can be in the electroplating process, the dissociation of nickel ions and sulfate ions. In the production of hardened oil, it is a catalyst for hydrogenation of oils and fats. The pharmaceutical industry for the production of vitamin C in the oxidation reaction of the catalyst. 

The inorganic industry is used as the main raw material for the production of other nickel salts such as ammonium sulfate, nickel oxide and nickel carbonate. For the production of phthalocyanine blue complexing agent for printing and dyeing industry, used as a dye vat dye. In addition, it can be used in the production of nickel cadmium battery etc..
