6018-89-9 Usage
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.
Chemical Properties
green monoclinic crystal(s); hygroscopic; used in textiles as a mordant [HAW93]
Uses
Different sources of media describe the Uses of 6018-89-9 differently. You can refer to the following data:
1. Nickel(II) acetate tetrahydrate can be used in synthesis of polynuclear-nickel polyoxotungstate cluster compounds that are ideal for the design of molecular magnets.
2. Nickel(II) Acetate Tetrahydrate is a reactant in the synthesis of metalloprophyrazines as active components of membranes of anion-selective electrodes.
3. Used in synthesis of polynuclear-nickel polyoxotungstate cluster compounds that are ideal for the design of molecular magnets.
Safety Profile

COMPOUNDS.
Purification Methods
The acetate crystallises from aqueous AcOH as the green tetrahydrate salt. It is soluble in 6 parts of H2O. It forms lower hydrates and should be kept in a well-sealed container. [Hardt & Pohlmann Z Anorg Allgem Chem 343 92 1966, Beilstein 2 IV 120.]
Check Digit Verification of cas no
The CAS Registry Mumber 6018-89-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,1 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6018-89:
(6*6)+(5*0)+(4*1)+(3*8)+(2*8)+(1*9)=89
89 % 10 = 9
So 6018-89-9 is a valid CAS Registry Number.
