Cobalt acetate

The Cobalt acetate, with the CAS registry number 71-48-7 and EINECS registry number 200-755-8, has the systematic name and IUPAC name of cobalt(2+) diacetate. It is the cobalt(II) salt of acetic acid with apparent of violet crystalline powder, and it belongs to the following product categories: Organic-metal salt; Cobalt; Micro/Nanoelectronics; Solution Deposition Precursors. The molecular formula of this chemical is C₄H₆CoO₄. What's more, it is usually used as catalyst for the produce of desiccant in coating, dye mordant and curing accelerator in glass.

The physical properties of Cobalt acetate 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: It may be prepared by the reaction between cobalt oxide or hydroxide and acetic acid:
CoO + 2 HC₂H₃O₂ → Co(C₂H₃O₂)₂ + H₂O

Uses of Cobalt acetate: It can react with salenH₂ to give salcomine, an oxygen-transport compound:
Co(OAc)₂ + salenH₂ → Co(salen) + 2 HOAc

You should be cautious while dealing with this chemical. It irritates to eyes, respiratory system and skin, and it is also harmful if swallowed. What's more, it may cause sensitization by skin contact and long-term adverse effects in the aquatic environment. Therefore, you had better take the following instructions: Do not breathe dust; Wear suitable protective clothing, gloves and eye/face protection, and in case of contacting with eyes, rinse immediately with plenty of water and seek medical advice; In case of accident or if you feel unwell, seek medical advice immediately (show label where possible).

You can still convert the following datas into molecular structure:
