Baumann, Eugen

In 1887, a number of new sulfur compounds were synthesized by Eugen Baumann at the University of Freiburg, Germany and evaluated by Alfred Kast. One of these, sul-fonal, was acquired and launched by Bayer in Germany. 

Poly(vinyl chloride). While PVC was initially formed by German chemist Eugen Baumann in 1872, scientists at B. F. Goodrich discovered in 1926 how to make sheets and adhesives from it, starting the vinyl age. PVC s many apphcations include water pipes and joints, building materials, food packaging, wire insulation, and medical components. 

When the base is hydroxide and the reaction is done in water, as in the preparation of 189, this reaction is known as the Schotten-Baumann reaction, after Carl Schotten (Germany 1853-1910) and Eugen Baumann (Germany 1846-1896). Just as amides are prepared from the reaction of carboxylic acid esters with amines or ammonia, so sulfonamides are prepared from sulfonate esters. An example is the reaction of ethyl butanesulfonate (190) with ammonia to give butanesulfonamide, 191. 

Polyvinyl chloride (PVC) is first created by Eugen Baumann...
