Specification
The CAS registry number of Nickel(II) acetate (1:2) is 373-02-4. With the EINECS registry number 239-086-1, its IUPAC name is nickel(2+) diacetate. It is an inorganic compound of nickel and acetic acid. What's more, it is a dull green odorless solid which soluble in water. It is used for electroplating. Besides, this inorganic compound is usually found as the tetrahydrate.
Physical properties about this chemical are: (1)ACD/LogP: -0.29; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): -1.07; (4)ACD/LogD (pH 7.4): -2.86; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1; (7)ACD/KOC (pH 5.5): 2.73; (8)ACD/KOC (pH 7.4): 1; (9)#H bond acceptors: 2; (10)#H bond donors: 1; (11)#Freely Rotating Bonds: 0; (12)Polar Surface Area: 37.3 Å2; (13)Flash Point: 40 °C; (14)Enthalpy of Vaporization: 23.7 kJ/mol; (15)Boiling Point: 117.1 °C at 760 mmHg; (16)Vapour Pressure: 13.9 mmHg at 25°C.
Preparation of Nickel(II) acetate (1:2): At first, add Ni(NO3)2·6H2O into acetic anhydride. Then heat the mixture until fierce reaction. After the reaction, via a series of cooling, washing by ethanoic anhydride and ethyl ether, vacuum drying in 80-90 °C you can get the desired product. The equation is as follows: Ni(NO3)2·6H2O+6(CH3CO)2O→Ni(CH3COO)2+2NO2+12O2+10CH3COOH+H2O.
