The first hydrogen peroxide plant to go on-stream based on the electrochemical process was in 1908 at the Osterreichische Chemische Werke in Weissenstein. The Weissenstein process was adapted in 1910 to afford the Miincher process developed by Pietzsch and Adolph at the Elecktrochemische Werke, Munich. In 1924, Reidel and Lowenstein used ammonium sulfate under the conditions of electrolysis instead of sulfuric acid, and the resulting ammonium peroxodisulfate (Reidel-Lowenstein process) or potassium peroxo-disulfate (Pietzsch-Adolph process) was hydrolysed to hydrogen peroxide. As a result of this process, production of hydrogen peroxide as 100% m/m rose to approximately 35 000 metric tonnes per annum.5... 

First operated in 1908 at the Osterreichische Chemische Werke, Weissenstein, Austria, and then by Degussa, Germany. This process, as well as the other electrolytic processes, was made obsolete by the invention of the AO process. 

Haber s work on ammonia synthesis began during the summer of 1904 not because of any planned, determined effort to solve an elusive task, but because of an unexpected request from the Osterreichische Chemische Werke in Vienna, a company set up by the brothers O. and R. Margulies. Haber did not immediately take up the offer he advised the brothers to take what was at that time the easiest route and recover by-product ammonia from coking. As he knew something about Ostwald s earlier work on the problem (but not about his unsuccessful deal with BASF and about the withdrawal of Ostwald s 1900 patent application), he wrote to him hoping that he would cooperate with the Margulies brothers.
