Adolph William Hermann Kolbe

Adolph William Hermann Kolbe (* 27. September 1818 in Elliehausen, today an urban district of Goettingen; † 25. November 1884 in Leipzig) was a German chemist.

Adolph William Hermann Kolbe

Kolbe visited the High School in Goettingen starting from 1831. After its chemistry study starting from 1838 with Friedrich better in Goettingen it became at the university Marburg 1842 assistant of Robert William Bunsen. Subsequently, it assisted Lyon Playfair at the university of London and was chemistry, written by Justus of Liebig and better, applied from 1847 to 1851 with the treatment hand dictionary of pure and, entrusted. Kolbe followed Bunsen in Marburg and went 1865 to the University of Leipzig.

At the time at that time one assumed organic and inorganic compounds are independent and organic compounds can be produced exclusively by living organisms. Kolbe was convinced that organic compounds from inorganic can be won directly or indirectly by substitution procedures. It confirmed its theory, by transferring Kohlenstoffdisulfid in several steps in acetic acid (1843-1845). With the introduction of a modified idea of structural radicals it contributed to the establishment of the structure theory . He predicted also the existence of secondary and tertiary alcohols .

He worked on the electrolysis of salts of the fatty acids and other acids, the Kolbe electrolysis bennnten after him and manufactured Salicylsäure , an important component for the production of aspirin. This procedure was called Kolbe synthesis ( or Kolbe Schmitt reaction). Natriumphenolat, which sodium - salt of the phenol, with carbon dioxide under pressure (100 bar, 125 °C) heats up, and the developing Natriumsalicylat with sulfuric acid is converted.

With Edward he discovered franc country that nitriles with the corresponding carbonic acids can be hydrolyzed. As a publisher for practical chemistry, starting from 1869, he reported journal occasionally very critically on the work of others.
