373-02-4 Usage
Uses
Different sources of media describe the Uses of 373-02-4 differently. You can refer to the following data:
1. Nickel acetate is used as a catalyst. It also is used as a dye mordant in textiles. Other applications are in electroplating nickel and as a sealer for anodizing aluminum.
2. Textiles (mordant), catalyst.
Preparation
Nickel acetate is prepared by reacting nickel hydroxide or nickel carbonate with dilute acetic acid. The tetrahydrate is crystallized from solution.
Ni(OH)2 + 2CH3COOH → (CH3COO)2Ni + 2H2O
NiCO3 + 2CH3COOH → (CH3COO)2Ni + CO2 + 2H2O
On heating, the solution hydrolyzes depositing nickel hydroxide.
Description
Nickel (II) acetate (Ni (CH3 COO)2 ) is an inorganic compound of nickel and acetic acid. This inorganic compound is usually found as the tetrahydrate. It is used for electroplating. It can be made by reacting nickel or nickel (II) carbonate with acetic acid. Ni + 2 CH3 COOH → C4 H6 NiO4 + H2 NiCO3 + 2 CH3 COOH → C4 H6 NiO4 + CO2 + H2 O The green tetrahydrate has been determined by X-ray crystallography to be octahedral about the central nickel atom, coordinated by four water molecules and two acetate fragments.It may be dehydrated in vacuo, by reaction with acetic anhydride,or by heat.
Chemical Properties
Different sources of media describe the Chemical Properties of 373-02-4 differently. You can refer to the following data:
1. Nickel(II) acetate crystallizes from solutions of the hydroxide in acetic acid at room
temperature as the green tetrahydrate. This is isomorphous with the cobalt(II) salt having a
distorted octahedral structure with the nickel atoms surrounded by four water molecules
and two oxygens from two acetato groups which are trans to each other. Its magnetic
moment is 3.30 BM at room temperature. The hygroscopic anhydrous acetate is obtained
by dehydration of the tetrahydrate in vacuo or by heating the tetrahydrate under reflux with
acetic anhydride. Like the tetrahydrate it is magnetically dilute at room temperature.
Upon thermal decomposition in nitrogen (or in vacuo) at 300° it evolves acetone, acetic acid,
carbon monoxide, carbon dioxide and water leaving nickel and N13C.
2. Green, monoclinic crystals; effloresces
somewhat in air.Soluble in water and alcohol.
Physical properties
The tetrahydrate is a green crystalline solid; sweet taste; odor of acetic acid; density 1.744 g/cm3; loses water on heating to form a yellow-green powder of anhydrous nickel acetate; decomposes above 250°C; soluble in water, 17g/100mL at 20°C; sparingly soluble in alcohol.
General Description
Dull green odorless solid. Sinks and mixes slowly with water.
Air & Water Reactions
Water soluble.
Reactivity Profile
Nickelous acetate is a green, crystalline material, mildly toxic and carcinogenic. Combustible when exposed to heat or flame. When heated to decomposition Nickelous acetate emits acrid smoke and irritating fumes [Lewis, 3rd ed., 1993, p. 909].
Hazard
Toxic by ingestion, a carcinogen (OSHA).
Health Hazard
Inhalation causes irritation of nose and throat. Ingestion causes vomiting. Contact with eyes causes irritation. May cause dermatitis in contact with skin.
Flammability and Explosibility
Nonflammable
Safety Profile
Confirmed carcinogen
with experimental neoplastigenic and
tumorigenic data. Poison by ingestion,
intraperitoneal, and subcutaneous routes.
Experimental reproductive effects. Mutation
data reported. When heated to
decomposition it emits irritating fumes. See
also NICKEL COMPOUNDS.
Safety
Nickel salts are carcinogenic and irritate the skin.
Check Digit Verification of cas no
The CAS Registry Mumber 373-02-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,7 and 3 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 373-02:
(5*3)+(4*7)+(3*3)+(2*0)+(1*2)=54
54 % 10 = 4
So 373-02-4 is a valid CAS Registry Number.

Late-Stage Derivatization of Buflavine by Nickel-Catalyzed Direct Substitution of a Methoxy Group via C-O Bond Activation
Shimazumi, Ryoma,Morita, Kosuke,Yoshida, Tomoki,Yasui, Kosuke,Tobisu, Mamoru
, p. 3037 - 3044 (2021/05/06)
The nickel-catalyzed cross-coupling of methoxyarenes was applied to buflavine, which allows for the selective monosubstitution of one of the two methoxy groups in the molecule, leading to the formation of 2- and 3-substituted isomers. Trimethylsilylmethyl (TMSCH 2), phenyl, and alkynyl groups can be introduced into buflavine using this method. The resulting TMSCH 2analogue of buflavine can also be converted into several other derivatives.
Synthesis and characterization of unique nickel(II) carboxylates and their coordination complexes
Shavina,Singh, Baljit
, p. 416 - 420 (2018/01/12)
Direct anodic dissolution of nickel metal and cathodic reduction of carboxylic acids (RCOOH) in acetonitrile has proved to be a simple and efficient one-step route to synthesize unique polymeric nickel(II) carboxylate complexes, {Ni(OOCR)2}n in H-type glass Pyrex cell. When the oxidation was carried out in the presence of neutral ligands (L) such as 2,2’-bipyridyl or 1,10-phenanthroline, the complexes of type {Ni(OOCR)2.L}n were obtained. Tetrabutylammonium chloride has been used as a supporting electrolyte in order to increase the electrolytic conductivity of the electrochemical system which in turn affects the current efficiency, cell voltage and energy consumption in the electrolytic cell. The complexes have been characterized by vibrational spectra, CHN elemental analysis, solubility and melting points shows a good agreement with the structure. The result also shows that the direct electrochemical synthetic technique has high current efficiency, extra purity and yield.
