Richard August Carl Emil Erlenmeyer (28 June 1825 – 22 January 1909), known simply as Emil Erlenmeyer, was a German chemist known for contributing to the early development of the theory of chemical structure and formulating the Erlenmeyer rule.
An Erlenmeyer flask, also known as a conical flask (British English) [1] or a titration flask, is a type of laboratory flask with a flat bottom, a conical body, and a cylindrical neck. It is named after the German chemist Emil Erlenmeyer (1825–1909), who invented it in 1860.
The word Erlenmeyer may mean: Richard August Carl Emil Erlenmeyer (1825–1909), German chemist; Erlenmeyer flask, conical glassware invented by Richard Erlenmeyer; The bony deformity named Deformity type Erlenmeyer flask because of the similarity to the shape of the flask; Friedrich Gustav Carl Emil Erlenmeyer (1864–1921), son of R. A. C. E ...
Friedrich Gustav Carl Emil Erlenmeyer (July 14, 1864 – February 8, 1921), also known as Emil Erlenmeyer, Jr., was a German chemist and the discoverer of the Erlenmeyer-Plöchl azlactone and amino acid synthesis. He was the son of Richard August Carl Emil Erlenmeyer and father of Hans Erlenmeyer.
The structure of two fused benzene rings was proposed by Emil Erlenmeyer in 1866, [17] and confirmed by Carl Gräbe three years later. [18] Physical properties.
Erlenmeyer flasks (introduced in 1861 by German chemist Emil Erlenmeyer (1825–1909)) are shaped like a cone, usually completed by the ground joint; the conical flasks are very popular because of their low price (they are easy to manufacture) and portability; Volumetric flask is used for preparing liquids with volumes of high precision. It is ...
A Büchner flask, also known as a vacuum flask, [1] filter flask, suction flask, side-arm flask, or Bunsen flask, is a thick-walled Erlenmeyer flask with a short glass tube and hose barb protruding about an inch from its neck.
The Erlenmeyer–Plöchl azlactone and amino acid synthesis, named after Friedrich Gustav Carl Emil Erlenmeyer who partly discovered the reaction, is a series of chemical reactions which transform an N-acyl glycine to various other amino acids via an oxazolone (also known as an azlactone).
