Adolph Wilhelm Hermann Kolbe ( September 27, 1818 – November 25, 1884) was a chemist.Kolbe was born in Elliehausen near Hanover, Germany.
He became an assistant to Robert Wilhelm Bunsen at the University of Marburg in 1842, after studying chemistry with Friedrich Wöhler. Subsequently he assisted Lyon Playfair at the University of London and from 1847 to 1851 was engaged in editing the Handwörterbuch der reinen und angewandten Chemie (Dictionary of Pure and Applied Chemistry) written by Justus von Liebig and Wöhler. Kolbe then succeeded Bunsen at Marburg, and in 1865 he went to the University of LeipzigLeipzig [ˈlaiptsɪç] ( Sorbian/Lusatian: Lipsk is the largest city in the federal state ( Bundesland) of Saxony in Germany. The name is derived from the Slavic word (see Sorbian) Lipsk (settlement where the linden trees stand). It is s.
At that time, it was believed that organic and inorganic compoundAn inorganic compound is a chemical compound not containing carbon. However, elemental carbon ( diamond or graphite) is typically considered inorganic, while methane, ethanol and similar simple hydrocarbons are referred to as organic compounds. Another kes are independent from each other, and that organic compounds could be created only by living organisms. Kolbe believed that organic compoundAn organic compound is any of a large class of chemical compounds whose molecules contain carbon, with exception of carbides, carbonates and carbon oxides. Organic compounds are studied in organic chemistry; many of them, such as proteins, fats, and carbos could be derived from inorganic ones, directly or indirectly, by substitution processes. He validated his theory by converting carbon disulfideCarbon disulfide (CS) is a colorless liquid with a pleasant odor that is like the smell of chloroform. The impure carbon disulfide that is usually used in most industrial processes is a yellowish liquid with an unpleasant odor, like that of rotting radish, in several steps, to acetic acidThe chemical compound acetic acid (from the Latin word acetum meaning "vinegar"), systematically called ethanoic acid is the acid that gives vinegar its sour taste. It is a carboxylic acid with chemical formula CHO, often written as CHCOOH to better refle (1843-45). Introducing a modified idea of structural radicals , he contributed to the establishment of structural theory . He also predicted the existence of secondary and tertiary alcoholIn general usage, alcohol (from Arabic al-khwl , or al-ghawl ) refers almost always to ethanol, also known as grain alcohol and often to any beverage that contains ethanol (see alcoholic beverage . This sense underlies the term alcoholism ( addiction to as.
He worked on the electrolysisThis article is about the chemical process. Electrolysis is also a method of epilation. In chemistry and manufacturing, electrolysis is a method of separating bonded elements and compounds by passing an electric current through them. Overview The source m of the salts of fattyIn chemistry, especially biochemistry, a fatty acid is a carboxylic acid (or organic acid), often with a long aliphatic tail (long chains), either saturated or unsaturated. Most of the natural fatty acids have an even number of carbon atoms, because they and other acids and prepared salicylic acid, a building block of aspirin. The process was named Kolbe synthesis (or Kolbe-Schmitt reaction), which works by heating sodium phenolate (the sodium salt of phenol) with carbon dioxide under pressure (100 atm, 125°C), then treating it with sulfuric acid.
With Edward Frankland he found that nitril es can be hydrolyzed to the corresponding acids. As editor of the Journal für praktische Chemie (Journal of practical chemistry, 1869), he was sometimes severely critical of the work of others.
He died in Leipzig, Germany
