Wilhelm Johann Schlenk (22 March 1879 – 29 April 1943) was a German chemist. He was born in Munich and also studied chemistry there. Schlenk succeeded Hermann Emil Fischer at the University of Berlin in 1919.
Schlenk was an organic chemist who discovered organolithium compounds around 1917. He also investigated free radicals and carbanions and discovered (together with his son) that organomagnesium halides are capable of participating in a complex chemical equilibrium, now known as a Schlenk equilibrium.
Today Schlenk is remembered mostly for developing techniques to handle air-sensitive compounds, and for his invention of the Schlenk flask. The latter is a reaction vessel with a glass or Teflon tap for the addition and removal of gases, such as nitrogen or argon. He is also known for the Schlenk line, a double manifold incorporating a vacuum system and a gas line joined by double oblique taps that allow the user to switch between vacuum and gas for the manipulation of air-sensitive compounds.
Famous quotes containing the word wilhelm:
“Public opinion contains all kinds of falsity and truth, but it takes a great man to find the truth in it. The great man of the age is the one who can put into words the will of his age, tell his age what its will is, and accomplish it. What he does is the heart and the essence of his age, he actualizes his age. The man who lacks sense enough to despise public opinion expressed in gossip will never do anything great.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
