Production method
Derived from the reaction of diacetyl monooxime and hydroxylamine-sodium sulfonate. Add diacetyl monooxime to the hydroxylamine-sodium sulfonate solution, heat to 70°C and maintain the temperature for several hours, and precipitate diacetyl oxime crystals. After cooling, filter immediately and wash with ice water until it no longer contains sulfate radicals. , That is. Hydroxylamine-sodium sulfonate can be prepared as follows: Mix sodium nitros Chemicalbook with crushed ice, add a suspension of sodium bisulfite and water while stirring, and then add glacial acetic acid from below the liquid surface under stirring. Then add concentrated hydrochloric acid and crushed ice to keep the reaction solution below 0°C, test the acid reaction with Congo red paper, filter to remove the insoluble precipitate to obtain hydroxylamine-sodium sulfonate solution.
