Nature
Green or grass-green monoclinic prism-like crystals. Relative density 11 921. Melting point 80 °c. Soluble in water, ethanol, its aqueous solution is slightly acidic. It is easily weathered in dry air and deliquescent in moist air. Upon heating above 140 °c, the water of crystallization is completely lost and the powder is yellow-brown in color.
Preparation Method
metal nickel Method: Add the gold scrap nickel into the acidolysis device containing a suitable amount of water or mother liquor, then add nitric acid and sulfuric acid to react to generate nickel sulfate solution, and send it to the neutralization reactor, adding soda ash solution for neutralization reaction to generate nickel carbonate, after filtering and separating sodium sulfate, wash with water
Nickel carbonate is added to the reactor and acidified with hydrochloric acid to form nickel chloride, hydrogen peroxide and barium salt are added to purify the solution, iron and sulfate are removed by filtration, and then concentrated by evaporation, cooled crystallization and centrifugal separation, finished nickel chloride hexahydrate was obtained. The nitrogen oxide gas released from the reaction can be absorbed by ammonia water to make ammonium nitrate by-product.
Use
used for nickel plating, as an anode activator in rapid nickel plating, and as an ammonia absorber in industrial or gas masks. For the manufacture of catalysts, preservatives, dry batteries. Used in the manufacture of other nickel salts. It is also used in the manufacture of cryptic inks.

Reference Information
| Overview | nickel chloride is green or grass-green monoclinic prism-like crystals at room temperature. In the dry air stroke, deliquescence in the humid air, in the vacuum can quickly absorb ammonia, heat lost part of the crystal water, more than 140 deg C when completely lost crystal water into yellow-brown anhydrous nickel chloride. Soluble in water, ethanol and ammonia, aqueous solution is acidic. The chemical industry is used to manufacture various nickel compounds, preservatives and catalysts for chemical reactions, and is also used to manufacture hidden inks, the electroplating industry is used for nickel plating, and is used as an analytical reagent in analytical chemistry, etc. In addition, the anhydrous substance is used as an ammonia absorbent for a gas mask. nickel reagent is toxic and carcinogenic, so it must be used with caution. |
| Chemical reaction | nickel chloride can be used as a mild Lewis acid to participate in the reaction, and can also catalyze the coupling reaction, and the metal hydride is used as a reducing reagent to participate in the selective reduction reaction. Nickel Chloride, as a mild Lewis acid, can achieve regioselective rearrangement of dienols in aqueous alcohol solutions. If the reaction is under the action of protic acid, the dehydrogenation product will be given. Under the action of other Lewis acids such as nickel acetate, palladium chloride and copper chloride, the yield is low, and only under the action of nickel chloride can a high yield be obtained. Similar to other metal halides, nickel chloride can be converted into low-cost metal reagents under the action of reducing reagents such as lithium aluminum hydride, thereby realizing selective reduction reactions for various functional groups, such as the reduction of olefins to alkanes, the alkyne is reduced to a cis-olefin, and a cleavage reaction of a N-O bond is achieved. Nickel chloride as a Lewis acid can also catalyze the reaction of cyanotrimethylsilanes with α,β-unsaturated acetals to give the corresponding α-cyano derivatives. The combination of nickel chloride and chromium dichloride is also effective in the reaction of aldehydes with vinyl iodide to give Allyl Alcohol compounds. This type of reaction allows the presence of various functional groups such as esters, amides, cyanides, ketones, acetals, ethers, silyl ethers, alcohols, alkenes and alkynes, thus enabling the efficient preparation of various types of allyl alcohol compounds. In the presence of phosphine ligands, nickel chloride and chromium dichloride catalytic systems are also capable of achieving enyne coupling reactions, such as for the formation of intramolecular enyne cyclization reactions. |

| production method | 1. NiCl2 · 6H2O powder was placed in a mill flask, thionyl chloride (SOCl2) was injected to cover the powder, a reflux condenser tube was fitted, and the mixture was heated to reflux for several hours. An amount of SOCl2 was distilled with a water bath. SOCl2 stained on the product can be removed by repeatedly applying a vacuum to the flask. 2. NiCl2. 6H2O was placed in a combustion tube, dried at 150 °c, then passed through a stream of HCl containing Cl2 and heated to 400 °c. After the production of the yellow colored NiCl2, one end of the tube was sealed, and the tube was heated to the maximum temperature that the tube could withstand with an oil pump vacuum to sublimate the product. To remove HCl, the sublimation product may be placed on top of KOH and annealed at 160 °c under high vacuum. |
