Skraup, Zdenko Hans
Born Mar. 3, 1850, in Prague; died Sept. 10, 1910, in Vienna. Austrian chemist.
Skraup was a professor at the Technische Hochschule in Graz from 1886 to 1906, when he became a professor at the University of Vienna. His research dealt mainly with synthesizing and defining the structure of alkaloids of the quinine group. In 1880, Skraup obtained quinoline by heating a mixture of aniline, glycerine, and sulfuric acid in the presence of nitrobenzene (the Skraup synthesis). His research on isomeric pyri-dinecarboxylic acids is well known. Skraup also studied carbohydrates and proteins; in 1901 he discovered cellobiose.
