  2. 2. History • Reaction was discovered by Bosch and was published in his 1905 book1,2 • Fritz Haber received a Nobel price in 1918 for the synthesis of ammonia from its constituents elements2 • Carl Bosch made it an industrial process to make explosives • First commercial high-pressure synthesis of ammonia in 19132 using Haber process • Ammonia is very useful – explosives, fertilizer, Ostwald process (1) Haber, F. The synthesis of ammonia from its elements Nobel Lecture, June 2, 1920. Resonance. 2002, 7, 86-94. (2) Fritz Haber – Biographical. 2014.
