MindMap Gallery Method for producing potassium hydroxide
The method for producing potassium hydroxide mainly includes the electrolytic process and chemical process. The electrolytic process involves electrolyzing a molten salt mixture containing potassium hydroxide to obtain metallic potassium and potassium hydroxide. The chemical process typically uses calcium hydroxide reacting with potassium carbonate, generating calcium carbonate precipitate and potassium hydroxide solution, which is then filtered, evaporated, crystallized, and other steps to produce the final product. Additionally, there is the causticizing process using natural minerals as raw materials, suitable for small-scale production. The choice of these methods depends on the availability of raw materials, cost, and production scale.
