Life

Carl Boettinger studied natural sciences at the University of Tübingen and was at Rudolph Fittig in Tübingen in 1873 with a thesis As to the decomposition of pyruvic acid doctorate .

Boettinger later published a number of papers on various topics of organic chemistry and most recently worked in his own chemical-technical laboratory in Darmstadt.

On March 1, 1890, Carl Boettinger was accepted as a member ( registration number 2866 ) of the German Academy of Natural Scientists Leopoldina . He was qualified as a professor.

In a paper published in 1876, he observed that the blue dye ultramarine sometimes had white spots around the edges where the sulfur was washed out, so he concluded that the color was due to sulfur atoms and the dye became blue through oxidation lost. In his opinion it was a combination of an aluminum soda silicate with sodium pentasulphide.
