footnotes =Richard August Carl Emil Erlenmeyer (
28 June 1825 –22 January 1909 ) was a Germanchemist , usually known simply as Emil Erlenmeyer. He was born inTaunusstein ,Germany .He spent some years as a
pharmacist after studying medicine.He studied at
Gießen but not underJustus von Liebig - rather he worked with Liebig's student Will and with Fresenius - and atHeidelberg under Friedrich Kekulé. He also associated himself withRobert Bunsen in the study offertilizer s. Erlenmeyer was professor of chemistry at theMunich Polytechnic School from 1868 to 1883. His experimental work included the discovery and synthesis of several organic compounds, e.g.,isobutyric acid (1865); in 1861 he invented the conical flask that bears his name. Among the first to adopt structural formulas based on valence, he proposed the modernnaphthalene formula of twobenzene rings sharing two carbon atoms.In 1880 he formulated the "
Erlenmeyer Rule ": Allalcohol s in which thehydroxyl group is attached directly to a double-bondedcarbon atom becomealdehyde s orketone s.He had to leave academic work in 1883 for health reasons, but continued to act as a consultant. Erlenmeyer died in
Aschaffenburg .References
