1.3 Synthetic Route

Nitric acid is added to cobalt hydroxide or cobalt phosphate, and recrystallized after reaction. Or use metal cobalt to react with nitric acid, add cobalt phosphate, adjust the pH value, filter to remove iron hydroxide, and then use nitric acid acidification, evaporation crystallization, can be prepared cobalt nitrate.

Synthesis method: add 30%~32% nitric acid to the acid-resistant reactor with stirring, slowly add metal cobalt particles under stirring for reaction, after the reaction is close to complete, steam is used to heat out nitrogen oxide gas, the solution is sent to the clarifier, cobalt carbonate is added under stirring to adjust the solution to pH 5 or so, kept warm at 80~90 °C for 1 day, filtered while hot to remove iron hydroxide precipitate, the filtrate is acidified to pH >1 with nitric acid, and then evaporated and concentrated to the relative density of the solution 1.6~1.7, and separated by cooling crystallization and centrifugation.
