Otto Ambros
Otto Ambros (19 May 1901 – 23 July 1990) was a German chemist and Nazi war criminal. He is known for his wartime work on synthetic rubber (polybutadiene, or "Buna rubber") and nerve agents (sarin and tabun). After the war he was tried at Nuremberg and convicted of crimes against humanity for his use of slave labor from the Auschwitz III–Monowitz concentration camp. Early life The son of a university professor, Ambros attended school and passed his Abitur exam in Munich. In 1920 he went to the University of Munich to study chemistry and agricultural science. In 1925 he gained a doctorate, studying under the 1915 Nobel Prize for Chemistry winner, Richard Willstätter. Career Beginning in 1926, Ambros worked at BASF in Ludwigshafen. In 1930 he spent a year studying in the Far East. From 1934 he worked at IG Farben, becoming head of their Schkopau plant in 1935. His division of IG Farben developed chemical weapons, including the nerve agents sarin (in 1938) and soman (in 1944 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weiden In Der Oberpfalz
Weiden in der Oberpfalz (official name: Weiden i.d.OPf.; Northern Bavarian: ''Weidn in da Owapfalz'') is a district-free city in Bavaria, Germany. It is located east of Nuremberg and west of the Czech border. A branch of the German Army is located here. History Weiden in der Oberpfalz was first mentioned in a document in 1241 as Weiden. It is assumed that the first settlements in Weiden are dated the year 1000. Located at the intersection of two major trading routes (Goldene Strasse and Magdeburger Strasse), Weiden soon became an important trading center with a population of 2,200 in 1531. An economic boom came along in 1863 when Weiden was connected to the railroad network. Some major companies of the glass and china industry settled in Weiden and the population increased.

War Merit Cross
The War Merit Cross (german: Kriegsverdienstkreuz) was a state decoration of Nazi Germany during World War II. By the end of the conflict it was issued in four degrees and had an equivalent civil award. A " de-Nazified" version of the War Merit Cross was reissued in 1957 by the ''Bundeswehr'' for its veterans. History This award was created by Adolf Hitler in October 1939 as a successor to the non-combatant Iron Cross which was used in earlier wars (similar medal but with a different ribbon). The award was graded in the same manner as the Iron Cross: ''War Merit Cross Second Class'', ''War Merit Cross First Class'', and ''Knights Cross of the War Merit Cross''. The award had two variants: ''with swords'' given to soldiers for exceptional service "not in direct connection with combat", and ''without swords'' given to civilians for meritorious service in "furtherance of the war effort". Recipients had to have the lower grade of the award before getting the next level. The weari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butadiene
1,3-Butadiene () is the organic compound with the formula (CH2=CH)2. It is a colorless gas that is easily condensed to a liquid. It is important industrially as a precursor to synthetic rubber. The molecule can be viewed as the union of two vinyl groups. It is the simplest conjugated diene. Although butadiene breaks down quickly in the atmosphere, it is nevertheless found in ambient air in urban and suburban areas as a consequence of its constant emission from motor vehicles. The name butadiene can also refer to the isomer, 1,2-butadiene, which is a cumulated diene with structure H2C=C=CH−CH3. This allene has no industrial significance. History In 1863, the French chemist E. Caventou isolated butadiene from the pyrolysis of amyl alcohol. This hydrocarbon was identified as butadiene in 1886, after Henry Edward Armstrong isolated it from among the pyrolysis products of petroleum. In 1910, the Russian chemist Sergei Lebedev polymerized butadiene and obtained a material wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poison Gas
Many gases have toxic properties, which are often assessed using the LC50 (median lethal dose) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits ( TLV, TWA or STEL) determined by the ACGIH professional association. Some, but by no means all, toxic gases are detectable by odor, which can serve as a warning. Among the best known toxic gases are carbon monoxide, chlorine, nitrogen dioxide and phosgene. Definition *Toxic: it is a chemical that has a median lethal concentration (LC50) in air of more than 200 parts per million (ppm) but not more than 2,000 parts per million by volume of gas or vapor, or more than 2 milligrams per liter but not more than 20 milligrams per liter of mist, fume or dust, when administered by continuous inhalation for 1 hour (or less if death occurs within 1 hour) to albino rats weighing between 200 and 300 grams each. ...

Mustard Gas
Mustard gas or sulfur mustard is a chemical compound belonging to a family of cytotoxic and blister agents known as mustard agents. The name ''mustard gas'' is technically incorrect: the substance, when dispersed, is often not actually a gas, but is instead in the form of a fine mist of liquid droplets.https://www.acs.org/content/dam/acsorg/education/resources/highschool/chemmatters/gc-mustard-gas-personal-safety-and-natl-security.pdf Mustard gases form blisters on exposed skin and in the lungs, often resulting in prolonged illness ending in death. The active ingredient in typical mustard gas is the organosulfur compound bis(2-chloroethyl) sulfide. In the wider sense, compounds with the structural element are known as ''sulfur mustards'' and ''nitrogen mustards'', respectively. Such compounds are potent alkylating agents, which can interfere with several biological processes. History as chemical weapons As a chemical weapon, mustard gas was first used in World War I, and has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soman
Soman (or GD, EA 1210, Zoman, PFMP, A-255, systematic name: ''O''-pinacolyl methylphosphonofluoridate) is an extremely toxic chemical substance. It is a nerve agent, interfering with normal functioning of the mammalian nervous system by inhibiting the enzyme cholinesterase. It is an inhibitor of both acetylcholinesterase and butyrylcholinesterase. As a chemical weapon, it is classified as a weapon of mass destruction by the United Nations according to UN Resolution 687. Its production is strictly controlled, and stockpiling is outlawed by the Chemical Weapons Convention of 1993 where it is classified as a Schedule 1 substance. Soman was the third of the so-called ''G-series'' nerve agents to be discovered along with GA (tabun), GB (sarin), and GF (cyclosarin). When pure, soman is a volatile, corrosive, and colorless liquid with a faint odor like that of mothballs or rotten fruit.
