Abstract:
     A new method for production of potassium argentocyanide is to use the basic material or base-releasing materiol to neutralize silver nitrate solution, then the neutrolizes silver nitrate solution is added to potassium cyanide solution to directly precipitate silver cyanide, and finally, silver cyanide reacts again with potassium cyanide to obtain potassium argentocyanide. As compared with the existing method, this invention does not pass through such procedures of evaporation, cooling, crystallization, drying, etc., greatly shortens the flow-path, and raises the economic benefit.
