| Use | used as oxidant and paint drying agent, printing and dyeing mordant, glass fiber reinforced plastic curing accelerator, etc. used as analytical reagent, Catalyst, dry paint, also used for ceramic glaze ingredients oxidation catalyst, paint drying agent, ceramic pigments, Analytical reagents. |
| production method | (1) metallic cobalt or cobalt oxide method? First, cobalt metal or cobalt oxide and nitric acid or sulfuric acid reaction, cobalt nitrate or cobalt sulfate, and then with sodium carbonate or ammonium bicarbonate reaction, cobalt carbonate, and then add acetic acid reaction, reaction products after evaporation, concentration, crystallization, spin drying to obtain the finished product. Each ton of product consumption of metal cobalt (>99%)265kg, acetic acid (industrial) 1000kg, sodium carbonate (industrial) 1200kg, nitric acid (industrial) 1100kg. (2) cobalt sulfate method? The cobalt sulfate and soda ash are heated to react to generate cobalt carbonate, and then react with acetic acid. The reaction product is filtered, concentrated, crystallized, dehydrated and packaged to obtain the product. 3. Add 5g of cobalt nitrate hexahydrate to 25ml of acetic anhydride, mix well, heat and boil for 10min, and precipitate crystals after standing. Suction filtration, washing with a small amount of acetic anhydride and ether. Dry. Dry under vacuum at 100 °c for 1H. |
