| titleOfInvention | A method of producing potassium ferricyanide from sodium ferrocyanide from coking industry |
| abstract | The invention relates to a method of producing potassium ferricyanide from sodium ferrocyanide from coking industry. The method includes mixing the sodium ferrocyanide from coking industry with water, adding charcoal to adsorb solid insoluble substances, filtering, adding potassium chloride and calcium chloride into the filtrate, reacting, filtering, adding the filter cake into a sodium carbonate solution, reacting, filtering, adding potassium chloride into the filtrate, feeding chlorine, adding a saturated potassium permanganate solution, adding hydrochloric acid to adjust the pH value of the system to be 7-8, filtering, and performing evaporative crystallization to obtain potassium ferricyanide crystal. The method is advantaged by simple process, easy industrialization, and the like. |
