Friedrich Bergius
Friedrich Karl Rudolf Bergius (, 11 October 1884 – 30 March 1949) was a German chemist known for the Bergius process for producing synthetic fuel from coal, Nobel Prize in Chemistry (1931, together with Carl Bosch) in recognition of contributions to the invention and development of chemical high-pressure methods. Having worked with IG Farben during World War II, his citizenship came into question following the war, causing him to ultimately flee to Argentina, where he acted as adviser to the Ministry of Industry. Early life Bergius was born near Breslau (Wrocław), then in the German Empire. Academic career Before studying chemistry, Bergius was sent to work for 6 months at the Friedrich Wilhelms steel works in Mülheim. His studies started at the University of Breslau in 1903 and ended with a PhD in chemistry at the University of Leipzig in 1907, after only 4 years. His thesis on sulfuric acid as solvent was supervised by Arthur Rudolf Hantzsch. In 1909 Bergius worked fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carl Bosch
Carl Bosch (; 27 August 1874 – 26 April 1940) was a German chemist and engineer and Nobel Laureate in Chemistry. He was a pioneer in the field of high-pressure industrial chemistry and founder of IG Farben, at one point the world's largest chemical company. He also developed the Haber–Bosch process, important for the large-scale synthesis of fertilizers and explosives. It is estimated that one-third of annual global food production uses ammonia from the Haber–Bosch process, and that this supports nearly half of the world's population. In addition, he co-developed the so-called Bosch-Meiser process for the industrial production of urea. Biography Early years Carl Bosch was born in Cologne to a successful gas and plumbing supplier. His father was Carl Friedrich Alexander Bosch (1843–1904) and his uncle was Robert Bosch, who pioneered the development of the spark plug and founded the multinational company Bosch.

Chemical Kinetics
Chemical kinetics, also known as reaction kinetics, is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. It is different from chemical thermodynamics, which deals with the direction in which a reaction occurs but in itself tells nothing about its rate. Chemical kinetics includes investigations of how experimental conditions influence the speed of a chemical reaction and yield information about the reaction's mechanism and transition states, as well as the construction of mathematical models that also can describe the characteristics of a chemical reaction. History The pioneering work of chemical kinetics was done by German chemist Ludwig Wilhelmy in 1850. He experimentally studied the rate of inversion of sucrose and he used integrated rate law for the determination of the reaction kinetics of this reaction. His work was noticed 34 years later by Wilhelm Ostwald. In 1864, Peter Waage and Cato Guldberg published the law ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Max Bodenstein
Max Ernst August Bodenstein (July 15, 1871 – September 3, 1942) was a German physical chemist known for his work in chemical kinetics. He was first to postulate a chain reaction mechanism and that explosions are branched chain reactions, later applied to the atomic bomb. Early life Max Bodenstein was born in Magdeburg on 15 July 1871 as the eldest son of Magdeburg merchant and brewer Franz Bodenstein (1834–1885) and his first wife Elise Meissner (1846–1876). Education In 1888, Max Bodenstein enrolled at the University of Heidelberg at the age of 17 to study chemistry with Carl Remigius Fresenius. On 25 October 1893, he received his PhD thesis: "''Über die Zersetzung des Jodwasserstoffes in der Hitze''" (On the degradation of hydrogen iodide in hot temperature), with Victor Meyer as his supervisor at the University of Heidelberg. Following graduation, Bodenstein received two years of additional training in Berlin-Charlottenburg and Göttingen. Bodenstein studied organic ...

Haber-Bosch Process
The Haber process, also called the Haber–Bosch process, is the main industrial procedure for the ammonia production, production of ammonia. It converts atmospheric nitrogen (N2) to ammonia (NH3) by a reaction with hydrogen (H2) using finely divided iron metal as a catalyst: \ce \qquad This reaction is exothermic but disfavored in terms of entropy because four equivalents of reactant gases are converted into two equivalents of product gas. As a result, high pressures and temperatures that are not too high are needed to Le_Chatelier's_principle, drive the reaction forward. The German chemists Fritz Haber and Carl Bosch developed the process in the first decade of the 20th century, and its improved efficiency over existing methods such as the Birkeland–Eyde process, Birkeland-Eyde and Frank–Caro process, Frank-Caro processes was a major advancement in the industrial production of ammonia. The Haber process can be combined with steam reforming to produce ammonia with just ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Karlsruhe
The Karlsruhe Institute of Technology (KIT; ) is both a German public university, public research university in Karlsruhe, Baden-Württemberg, and a research center of the Helmholtz Association. KIT was created in 2009 when the University of Karlsruhe (), founded in 1825 as a public research university and also known as the "Fridericiana", merged with the Karlsruhe Research Center (), which had originally been established in 1956 as a national nuclear research center (, or KfK). KIT is thus the first and only institution in Germany to overcome the division of the German scientific and research landscape into academic and non-academic institutions in the form of a merger of two different types of institutions. KIT is a member of the TU9, an incorporated society of the largest and most notable German institutes of technology. As part of the German Universities Excellence Initiative KIT was one of three universities which were awarded excellence status in 2006. In the following "G ...

Fritz Haber
Fritz Jakob Haber (; 9 December 1868 – 29 January 1934) was a German chemist who received the Nobel Prize in Chemistry in 1918 for his invention of the Haber process, a method used in industry to synthesize ammonia from nitrogen gas and hydrogen gas. This invention is important for the large-scale synthesis of fertilizers and Explosive material, explosives. It is estimated that a third of annual global food production uses ammonia from the Haber–Bosch process, and that this food supports nearly half the world's population. For this work, Haber has been called one of the most important scientists and industrial chemists in human history. Haber also, along with Max Born, proposed the Born–Haber cycle as a method for evaluating the lattice energy of an ionic solid. Haber, a known German nationalist, is also considered the "father of chemical warfare" for his years of pioneering work developing and Chlorine#Use as a weapon, weaponizing chlorine and other poisonous gases during ...

Sulfuric Acid
Sulfuric acid (American spelling and the preferred IUPAC name) or sulphuric acid (English in the Commonwealth of Nations, Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen, and hydrogen, with the molecular formula . It is a colorless, odorless, and Viscosity, viscous liquid that is Miscibility, miscible with water. Pure sulfuric acid does not occur naturally due to its Dehydration reaction, strong affinity to water vapor; it is Hygroscopy, hygroscopic and readily absorbs water vapor from the Atmosphere of Earth, air. Concentrated sulfuric acid is a strong oxidant with powerful dehydrating properties, making it highly corrosive towards other materials, from rocks to metals. Phosphorus pentoxide is a notable exception in that it is not dehydrated by sulfuric acid but, to the contrary, dehydrates sulfuric acid to sulfur trioxide. Upon addition of sulfuric acid to water, a considerable amount of heat is releas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
