Oscar Loew
Oscar Loew (2 April 1844 – 26 January 1941) was a German agricultural chemist, active in Germany, the United States, and Japan in the late 19th and early 20th centuries. Biography Loew was born in Marktredwitz, Bavaria, where his father was a pharmacist. He studied at the University of Munich under the noted chemist Justus von Liebig; he was Liebig's last student. Loew was an assistant in plant physiology at the City College of New York and participated in four expeditions to the southwestern United States in 1882 before returning to Munich, Germany, where he collaborated with Carl Nägeli. Loew became associate professor at Munich University in 1886. In 1893, he was recruited by the Meiji government of Japan as a foreign advisor, and travelled to Tokyo, where he remained until 1898. Loew served as instructor at Tokyo Imperial University between 1893 and 1907, succeeding Oskar Kellner as professor of agricultural chemistry there. He trained many notable Japanese chemists ...

Oyatoi Gaikokujin
The foreign employees in Meiji Japan, known in Japanese as ''O-yatoi Gaikokujin'' (Kyūjitai: , Shinjitai: , "hired foreigners"), were hired by the Japanese government and municipalities for their specialized knowledge and skill to assist in the modernization of the Meiji period. The term came from ''Yatoi'' (a person hired temporarily, a day laborer), was politely applied for hired foreigner as ''O-yatoi gaikokujin''. The total number is over 2,000, probably reaches 3,000 (with thousands more in the private sector). Until 1899, more than 800 hired foreign experts continued to be employed by the government, and many others were employed privately. Their occupation varied, ranging from high salaried government advisors, college professors and instructor, to ordinary salaried technicians. Along the process of the opening of the country, the Tokugawa Shogunate government first hired, German diplomat Philipp Franz von Siebold as diplomatic advisor, Dutch naval engineer Hendrik Harde ...

Catalyst
Catalysis () is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst (). Catalysts are not consumed in the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recycles quickly, very small amounts of catalyst often suffice; mixing, surface area, and temperature are important factors in reaction rate. Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process of regenerating the catalyst. Catalysis may be classified as either homogeneous, whose components are dispersed in the same phase (usually gaseous or liquid) as the reactant, or heterogeneous, whose components are not in the same phase. Enzymes and other biocatalysts are often considered as a third category. Catalysis is ubiquitous in chemical industry of all kinds. Estimates are that 90% of all commercially produced chemical products involve catalysts at some sta ... [...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, h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formaldehyde
Formaldehyde ( , ) ( systematic name methanal) is a naturally occurring organic compound with the formula and structure . The pure compound is a pungent, colourless gas that polymerises spontaneously into paraformaldehyde (refer to section Forms below), hence it is stored as an aqueous solution (formalin), which is also used to store animal specimens. It is the simplest of the aldehydes (). The common name of this substance comes from its similarity and relation to formic acid. Formaldehyde is an important precursor to many other materials and chemical compounds. In 1996, the installed capacity for the production of formaldehyde was estimated at 8.7 million tons per year. It is mainly used in the production of industrial resins, e.g., for particle board and coatings. Forms Formaldehyde is more complicated than many simple carbon compounds in that it adopts several diverse forms. These compounds can often be used interchangeably and can be interconverted. *Molecular for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Organic Chemistry
Organic chemistry is a subdiscipline within chemistry involving the science, scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms.Clayden, J.; Greeves, N. and Warren, S. (2012) ''Organic Chemistry''. Oxford University Press. pp. 1–15. . Study of structure determines their structural formula. Study of properties includes Physical property, physical and Chemical property, chemical properties, and evaluation of Reactivity (chemistry), chemical reactivity to understand their behavior. The study of organic reactions includes the organic synthesis, chemical synthesis of natural products, drugs, and polymers, and study of individual organic molecules in the laboratory and via theoretical (in silico) study.

Lime (mineral)
Lime is a calcium-containing inorganic material composed primarily of oxides and hydroxide, usually calcium oxide and/or calcium hydroxide. It is also the name for calcium oxide which occurs as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. The International Mineralogical Association recognizes lime as a mineral with the chemical formula of CaO. The word ''lime'' originates with its earliest use as building mortar and has the sense of ''sticking or adhering''. These materials are still used in large quantities as building and engineering materials (including limestone products, cement, concrete, and mortar), as chemical feedstocks, and for sugar refining, among other uses. Lime industries and the use of many of the resulting products date from prehistoric times in both the Old World and the New World. Lime is used extensively for wastewater treatment with ferrous sulfate. The rocks and minerals from which these materials are derived, typ ...

Agricultural Chemistry
Agricultural chemistry is the study of chemistry, especially organic chemistry and biochemistry, as they relate to agriculture—agricultural production, the processing of raw products into foods and beverages, and environmental monitoring and remediation. These studies emphasize the relationships between plants, animals and bacteria and their environment. As a branch of agricultural science, agricultural chemistry studies the chemical compositions and reactions involved in the production, protection, and use of crops and livestock. Its basic science aspects embrace, in addition to test-tube chemistry, all the life processes through which humans obtain food and fiber for themselves and feed for their animals. Its applied science and technology aspects are directed toward control of those processes to increase yields, improve quality, and reduce costs. One important branch of it, chemurgy, is concerned chiefly with utilization of agricultural products as chemical raw materials ...
