Griesheim
Griesheim :
(1) An early process for producing chlorine by electrolysis, developed by Chemische Fabrik Griesheim-Elektron, in Germany, and commercialized in 1890. The electrolyte was saturated potassium chloride solution, heated to 80 to 90°C. The byproduct potassium hydroxide was recovered. The process was superseded in the United States by several similar electrolytic processes before being ousted by the mercury cell, invented by H. Y. (2) A process for making potassium by reducing potassium fluoride with calcium carbide: 2KF + CaC2 = CaF2 + 2C + 2K. (Check source for accuracy of chemical formula)
