| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| use | catalyst for xylene oxidation, desiccant, printing and dyeing mordant, glass fiber reinforced plastic curing accelerator and hidden ink for the production of coatings. catalyst for xylene oxidation is used for surface treatment of aluminum profiles, desiccant for producing coatings, printing and dyeing mordant, glass fiber reinforced plastic curing accelerator and hidden ink, etc. |
| production method | cobalt nitrate solution is prepared by reacting metal cobalt or cobalt oxide with nitric acid, and then reacting with ammonium bicarbonate (or soda ash) solution to generate cobalt carbonate precipitation; The precipitate is washed, separated, and acidified with acetic acid to obtain cobalt acetate; After filtration, adjust the reaction solution to pH = 2, concentrate until the relative density of the solution is 1.17-1.20, then add 1kg of acetic acid every 200L of concentrated solution, crystallize for 7-10d at a temperature lower than 20 ℃, centrifuge and dry at 30-40 ℃ to obtain the finished product. The industrial grade cobalt acetate content is not less than 45%. Raw material consumption quota: metal cobalt (>99%)265kg/t, acetic acid 1000kg/t, nitric acid 1100kg/t. |
