During the chlorine-alkali electrolysis process, salt (sodium chloride - NaCl) is separated into its components chlorine and sodium. The sodium part is further processed in various derivatives, for example as soda lye or caustic soda, as well as sodium hypochlorite. Chlorine is used in many applications. Its largest application area is the manufacturing of plastics such as polyvinylchloride (PVC), polycarbonate, or as intermediate product isocyanate (MDI) in polyurethane synthesis. For the highest requirements of the various electrolysis technologies, K+S Minerals and Agriculture GmbH offers a great number of rock and vacuum salt qualities.
Due to its low content of secondary components, potassium chloride produced by K+S Minerals and Agriculture GmbH is well suited for chlor-alkali electrolysis (classic amalgam and membrane process). It is used successfully in the production of potassium hydroxide all over the world.
