JOHANN WOLFGANG DOBEREINER (178o--1849) ,German chemist, was
See also:born near
See also:Hof in
See also:Bavaria on the 15th of
See also:December 1780 . After studying
See also:pharmacy at Munchberg, he started a chemical manufactory in 1803, and in 1810 was appointed
See also:professor of chemistry, pharmacy and technology at
See also:Jena, where he died on the 24th of
See also:March 1849 . The Royal Society's
See also:Catalogue enumerates 171 papers by him on various chemical topics, but his name is best known for his experiments on platinum in a minute state of division and on the oxidation products of
See also:alcohol . In 1822 he showed that when a mass of platinum black, supplied with alcohol by a
See also:wick is enclosed in a
See also:jar to which the air has limited
See also:access, acetic acid and
See also:water are produced; this experiment formed the basis of the Schtitzenbach
See also:Process . A
See also:year later he noticed that spongy platinum in presence of
See also:oxygen canbring about the ignition of hydrogen, and utilized this fact to construct his " hydrogen lamp," the prototype of numerous devices for the self-ignition of
See also:gas burners . He studied the formation of aldehyde from alcohol by various methods, also obtaining its crystalline compound with
See also:ammonia, and he was the discoverer of furfurol . An early observation of the diffusion of gases was recorded by him in '823 when he noticed the
See also:escape of hydrogen from a cracked jar, attributing it to the capillary
See also:action of fissures . His
See also:works included
See also:treatises on pneumatic chemistry (1821-1825) and the chemistry of
See also:fermentation (1822) . A
See also:correspondence which he carried on with Goethe and
See also:grand-duke of Saxe-
