Ammonia Fritz Haber

In 1918, Fritz Haber won the Nobel Prize for the synthesis of ammonia from its elements. In other words, Fritz Haber was the first chemist to create ammonia in a laboratory. His discovery made it possible to manufacture industrial-sized quantities of ammonia that could be added to fertilizers. (Check out Chapter 17 for details on why ammonia is a useful fertilizer.) Manufacturing ammonia led to increased crop yields and transformed farming, shaping the production of foods you eat today. It s arguably the most important development in agriculture since the development of irrigation (6,000 BC) and the use of draft animals (4,000 BC). [Pg.316]


Chemistry s relationship to the public is unique among the sciences. Chemistry s products become part of our everyday lives and are profoundly intertwined with society s tastes, needs, and desires. Fritz Haber s ammonia for fertilizing crops helped raise chemistry s prestige to such a peak early in the twentieth century that an adoring public supported the massive deploy-... [Pg.199]

M Fritz Haber first used osmium for the synthesis of ammonia. The rare and expensive element was soon replaced by the cheapest iron. [Pg.73]

A second and greater opportunity came his way in the spring of 1922. Professor Fritz Haber, discoverer of the Haber ammonia synthesis process and head of the Kaiser Wilhelm Institute for Physical Chemistry (now known as the Max Planck Institute), contacted Professor Schlenk. [Pg.14]

Before World War I, tbe main source of nitrates for human use was from large deposits of bird droppings in Peru and sodium nitrate from Chile. These sources were becoming scarce and expensive. Then Fritz Haber (1868-1934), a lecturer in a technical college in Germany, began to experiment with ways to manufacture ammonia. Haber knew that ammonia could he easily converted to nitrates and other useful nitrogen... [Pg.367]

A central scientific accomplishment made a huge impact on the fertilizer situation. Fritz Haber developed the means to convert nitrogen to ammonia in the chemistry laboratory. The chemical reaction that leads from elemental nitrogen to ammonia involves combination with elemental hydrogen ... [Pg.68]

Fritz Haber is a major contributor to human welfare through finding the means to convert elemental nitrogen into ammonia. That is the heroic side of Fritz Haber. He is also known as the father of chemical warfare based on his development of chlorine as a lethal gas during World War 1. Haber was Germany s tsar of gas warfare. He went to the front personally to oversee the placement of chlorine tanks as gas warfare weapons. [Pg.69]

To conclude, it is worth recording the advice given to the author at the very start of his career by the veteran catalytic chemist Alwin Mittasch, who had been Fritz Haber s officer in charge of catalyst research for the ammonia synthesis In all catalytic studies only the very purest is good enough . [Pg.132]

Reactions which may occur on sites consisting of one or two atoms only on the surface of the catalyst are generally known as facile reactions. Reactions involving hydrogenation on metals are an example. Eor such reactions, the state of dispersion or preparation methods do not greatly affect the specific activity of a catalyst. In contrast, reactions in which some crystal faces are much more active than others are called structure sensitive. An example is ammonia synthesis (discovered by Fritz Haber in 1909 (Moeller 1952)) over Fe catalysts where (111) Fe surface is found to be more active than others (Boudart 1981). Structure-sensitive reactions thus require sites with special crystal structure features, which... [Pg.152]

Fritz Haber was born on December 9, 1868 in Breslau, Germany. Haber s research work (1905-1911) on the equilibrium between nitrogen and hydrogen to form ammonia by establishing the exact temperature and pressure, as well as the catalyst to produce the compound. [Pg.79]

The Germans need to supplant Chilean saltpeter supply, which could be cut off by enemy blockades, led to the search for methods to synthesize nitrates. The reaction required a supply of ammonia, which was economically synthesized by Fritz Haber (1868—1934) before World War I (see Ammonia). Ammonia could then be converted to nitric acid through the Ostwald process and then nitric acid can be reacted with bases to produce nitrates (see Nitric Acid) KOH + HNO 4 - KNO. + HO... [Pg.230]

In the early 1900s, the German chemist Fritz Haber discovered that a catalyst consisting of iron mixed with certain metal oxides causes the reaction to occur at a satisfactory rate at temperatures where the equilibrium concentration of NH3 is reasonably favorable. The yield of NH3 can be improved further by running the reaction at high pressures. Typical reaction conditions for the industrial synthesis of ammonia are 400-500°C and 130-300 atm. [Pg.557]

Fritz Haber, bom in Breslau, Prussia (now Wroclaw, Poland), successfully applied physical chemistry to technological problems. In 1918 he won the Nobel Prize in chemistry for his synthesis of ammonia from the elements, an important starting material in the production of fertilizers and explosives. [Pg.182]

German chemist Fritz Haber, recipient of the 1918 Nobel Prize in chemistry, for the synthesis of ammonia from its elements. ... [Pg.183]

Fritz Haber developed the Haber Process for synthesizing ammonia from hydrogen and nitrogen using an iron catalyst. Ammonia is still produced by this method to make fertilizers, textiles, and other products. [Pg.232]

The balanced equation that we will use for this stoichiometry explanation is the recipe for the manufacture of ammonia (NH3). This reaction was so important that the chemist responsible for it, Fritz Haber, was awarded the Nobel Prize. Ammonia is a gateway step in the manufacture of fertilizers, and its manufacture was a giant step in solving the problem of providing food to a world population growing at an exponential rate. The equation for the Haber process is... [Pg.49]

Ammonia is an important base, used to make fertilizers, nylon, and nitric acid. The manufacture of ammonia depends on a process discovered by Fritz Haber (1868-1934). After gathering information from print or electronic resources, write an obituary for Haber. Describe his accomplishments and the effect on society of plentiful supplies of ammonia. [Pg.406]
