Leunawerke
The Leuna works (german: Leunawerke) in Leuna, Saxony-Anhalt, is one of the biggest chemical industrial complexes in Germany. The site, now owned jointly by companies such as Total S.A., BASF, Linde AG, and DOMO Group, covers 13 km2 and produces a very wide range of chemicals and plastics. Origins Ammonia is an important intermediate product for the manufacture of nitric acid and other nitrogen compounds, needed to produce fertilizers and explosives in particular. The increasing demand for explosives during World War I exceeded the ammonia production capacities of the Oppau works of BASF, who owned the patents for the Haber process. Leuna in central Germany, out of range of French aircraft, was selected as the location of a second plant named ''Badische Anilin- und Sodafabrik, Ammoniakwerk Merseburg''. Construction started on 25 May 1916, and the first tank car with ammonia left the works in April 1917. In 1920 the ammonia works of Leuna and Oppau merged into ...

Leuna
Leuna is a town in Saxony-Anhalt, eastern Germany, south of Merseburg and Halle, on the river Saale. The town is known for the ''Leunawerke'', at 13 km2 one of the biggest chemical industrial complexes in Germany, where a very wide range of chemicals and plastics is produced. In 1960, Leuna's population was nearly 10,000, but after reunification high unemployment rates and poor living conditions, including pollution from nearby industries, caused significant outward migration. Before the 31 December 2009 incorporation of ten neighbouring municipalities, its population had declined to 6,670. Geography The town Leuna consists of Leuna proper and the following 10 ''Ortschaften'' or municipal divisions:Hauptsatzung der Stadt Leuna July 2020. * |
Buna Werke Schkopau
Buna Werke Schkopau were a chemical company specialising in the production of polymer materials such as plastics and artificial rubber. The name BUNA is derived from the technology of polymerising butadiene with sodium (chemical symbol: Na) as a catalyst. History In order to make Germany independent from the importation of natural rubber, the first industrial plant for the production of artificial rubber was built in Schkopau near Halle (Saale) and named ''Buna-Werke GmbH Schkopau''. It was a subsidiary of ''Ammoniakwerk Merseburg GmbH'', later known as ''Leunawerke'', which belonged to IG Farben. The foundation stone was laid in April 1936. Production of artificial rubber started in 1937. Other products were PVC and basic chemicals such as trichlorethylene, formaldehyde, tetrahydrofuran, acetic acid, and acetone. Another factory, ''Hüls-Werke'' in Marl started production of Buna rubber in 1939. World War II During World War II, a branch of Buna-Werke was built near Auschw ...

Hydrogen
Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element. At standard conditions hydrogen is a gas of diatomic molecules having the formula . It is colorless, odorless, tasteless, non-toxic, and highly combustible. Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all normal matter.However, most of the universe's mass is not in the form of baryons or chemical elements. See dark matter and dark energy. Stars such as the Sun are mainly composed of hydrogen in the plasma state. Most of the hydrogen on Earth exists in molecular forms such as water and organic compounds. For the most common isotope of hydrogen (symbol 1H) each atom has one proton, one electron, and no neutrons. In the early universe, the formation of protons, the nuclei of hydrogen, occurred during the first second after the Big Bang. The emergence of neutral hydrogen atoms throughout the universe occurred about 370,000 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Communist Workers Party Of Germany
The Communist Workers' Party of Germany (german: Kommunistische Arbeiter-Partei Deutschlands; KAPD) was an anti-parliamentarian and left communist party that was active in Germany during the time of the Weimar Republic. It was founded in April 1920 in Heidelberg as a split from the Communist Party of Germany (KPD). Originally the party remained a "sympathising member of Communist International." In 1922 the KAPD split into two factions, both of whom kept the name but are referred to as the KAPD Essen Faction and the KAPD Berlin Faction. The KAPD Essen Faction was linked to the Communist Workers International. The Entschiedene Linke decided unanimously to join the KAPD during its congress of 4–6 June 1927. History The roots of the KAPD lie in the left-wing split from the Social Democratic Party of Germany (SPD), calling itself the International Socialists of Germany (ISD). The ISD consisted of elements which were to the left of the Spartacus League of Rosa Luxemburg and Karl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kapp Putsch
The Kapp Putsch (), also known as the Kapp–Lüttwitz Putsch (), was an attempted coup against the German national government in Berlin on 13 March 1920. Named after its leaders Wolfgang Kapp and Walther von Lüttwitz, its goal was to undo the German Revolution of 1918–1919, overthrow the Weimar Republic, and establish an autocratic government in its place. It was supported by parts of the ''Reichswehr'', as well as nationalist and monarchist factions. Although the legitimate German government was forced to flee the city, the coup failed after a few days, when large sections of the German population joined a general strike called by the government. Most civil servants refused to cooperate with Kapp and his allies. Despite its failure, the Putsch had significant consequences for the future of the Weimar Republic. It was also one of the direct causes of the Ruhr uprising a few weeks later, which the government suppressed by military force, after having dealt leniently with lea ...

Synthetic Rubber
A synthetic rubber is an artificial elastomer. They are polymers synthesized from petroleum byproducts. About 32-million metric tons of rubbers are produced annually in the United States, and of that amount two thirds are synthetic. Synthetic rubber, just like natural rubber, has many uses in the automotive industry for tires, door and window profiles, Seal (mechanical), seals such as O-rings and gaskets, hoses, Belt (mechanical), belts, Rubber mat, matting, and flooring. They offer a different range of physical and chemical properties, so can improve the reliability of a given product or application. Synthetic rubbers are superior to natural rubbers in two major respects, thermal stability and resistance to oils and related compounds. They are more resistant to oxidizing agents, such as oxygen and ozone which can reduce the life of products like tires. History of synthetic rubber The expanded use of bicycles, and particularly their pneumatic tires, starting in the 1890s, create ...

Petroleum
Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, and is found in geological formations. The name ''petroleum'' covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure. Petroleum is primarily recovered by oil drilling. Drilling is carried out after studies of structural geology, sedimentary basin analysis, and reservoir characterisation. Recent developments in technologies have also led to exploitation of other unconventional reserves such as oil sands and oil shale. Once extracted, oil is refined and separated, most easily by distillation, into innumerable products for direct use or use in manufacturing. Products include fuels such as gasol ...

Detergent
A detergent is a surfactant or a mixture of surfactants with cleansing properties when in dilute solutions. There are a large variety of detergents, a common family being the alkylbenzene sulfonates, which are soap-like compounds that are more soluble in hard water, because the polar sulfonate (of detergents) is less likely than the polar carboxylate (of soap) to bind to calcium and other ions found in hard water. Definitions The word ''detergent'' is derived from the Latin adjective ''detergens'', from the verb ''detergere'', meaning to wipe or polish off. Detergent is a surfactant or a mixture of surfactants with cleansing properties when in dilute solutions. However, conventionally, detergent is used to mean synthetic cleaning compounds as opposed to ''soap'' (a salt of the natural fatty acid), even though soap is also a detergent in the true sense. In domestic contexts, the term ''detergent'' refers to household cleaning products such as ''laundry detergent'' or '' dish ...

Amine
In chemistry, amines (, ) are compounds and functional groups that contain a basic nitrogen atom with a lone pair. Amines are formally derivatives of ammonia (), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group (these may respectively be called alkylamines and arylamines; amines in which both types of substituent are attached to one nitrogen atom may be called alkylarylamines). Important amines include amino acids, biogenic amines, trimethylamine, and aniline; Inorganic derivatives of ammonia are also called amines, such as monochloramine (). The substituent is called an amino group. Compounds with a nitrogen atom attached to a carbonyl group, thus having the structure , are called amides and have different chemical properties from amines. Classification of amines Amines can be classified according to the nature and number of substituents on nitrogen. Aliphatic amines contain only H and alkyl substituents. A ...

Petrol
Gasoline (; ) or petrol (; ) (see ) is a transparent, petroleum-derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines (also known as petrol engines). It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives. On average, U.S. refineries produce, from a barrel of crude oil, about 19 to 20 gallons of gasoline; 11 to 13 gallons of distillate fuel (most of which is sold as diesel fuel); and 3 to 4 gallons of jet fuel. The product ratio depends on the processing in an oil refinery and the crude oil assay. A barrel of oil is defined as holding 42 US gallons, which is about 159 liters or 35 imperial gallons. The characteristic of a particular gasoline blend to resist igniting too early (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating, which is produced in several grades. Tetraethyl lead and other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methanol
Methanol (also called methyl alcohol and wood spirit, amongst other names) is an organic chemical and the simplest aliphatic alcohol, with the formula C H3 O H (a methyl group linked to a hydroxyl group, often abbreviated as MeOH). It is a light, volatile, colourless, flammable liquid with a distinctive alcoholic odour similar to that of ethanol (potable alcohol). A polar solvent, methanol acquired the name wood alcohol because it was once produced chiefly by the destructive distillation of wood. Today, methanol is mainly produced industrially by hydrogenation of carbon monoxide. Methanol consists of a methyl group linked to a polar hydroxyl group. With more than 20 million tons produced annually, it is used as a precursor to other commodity chemicals, including formaldehyde, acetic acid, methyl tert-butyl ether, methyl benzoate, anisole, peroxyacids, as well as a host of more specialised chemicals. Occurrence Small amounts of methanol are present in normal, healthy hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IG Farben
Interessengemeinschaft Farbenindustrie AG (), commonly known as IG Farben (German for 'IG Dyestuffs'), was a German chemical and pharmaceutical conglomerate (company), conglomerate. Formed in 1925 from a merger of six chemical companies—BASF, Bayer, Hoechst AG, Hoechst, Agfa-Gevaert, Agfa, Chemische Fabrik Griesheim-Elektron, and Weiler-ter-Meer, Chemische Fabrik vorm. Weiler Ter Meer—it was seized by the Allies after World War II and divided back into its constituent companies. IG Farben was once the largest company in Europe and the largest chemical and pharmaceutical company in the world. IG Farben scientists made fundamental contributions to all areas of chemistry and the pharmaceutical industry. Otto Bayer discovered the polyaddition for the synthesis of polyurethane in 1937, and three company scientists became List of Nobel laureates, Nobel laureates: Carl Bosch and Friedrich Bergius in 1931 "for their contributions to the invention and development of chemical high pre ...
