Specification
The Nickel acetate tetrahydrate, with the CAS registry number 6018-89-9 and EINECS registry number 206-761-7, has the systematic name of nickel(2+) acetate hydrate (1:2:4). It is a kind of hygroscopic green monoclinic crystal. And the molecular formula of this chemical is C4H16NiO8. What's more, it is usually used as chemical reagent, and it is also used as catalyst in the nickelage and coloration of metal and nickelage.
The physical properties of Nickel acetate tetrahydrate are as followings: (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: Dissolve the basic nickel carbonate in excessive dilute acetic acid. Then, after a series of filtration, evaporation, cooling crystallization and drying, you can get product.
