Richard August Carl Emil Erlenmeyer
Richard August Carl Emil Erlenmeyer (28 June 182522 January 1909), known simply as Emil Erlenmeyer, was a German chemist known for contributing to the early development of the theory of structure, formulating the Erlenmeyer rule, and designing the Erlenmeyer flask, a type of specialized flask, ubiquitous in chemistry laboratories, which is named after him. Biography Earlyl life and education Erlenmeyer was born in Wehen, Duchy of Nassau (today Taunusstein, Hesse, near Wiesbaden), in 1825, the son of a Protestant minister. He enrolled in the University of Giessen to study medicine, but after attending lectures of Justus von Liebig changed to chemistry. In the summer of 1846 he went to Heidelberg for one year, and studied physics, botany and mineralogy, returning to Giessen in 1847. After serving as assistant to H. Will and then to Carl Remigius Fresenius, Erlenmeyer decided to devote himself to pharmaceutical chemistry. For this purpose he studied in Nassau, where he passed ...

Erlenmeyer Flask
An Erlenmeyer flask, also known as a conical flask (British English) or a titration flask, is a type of laboratory flask which features a flat bottom, a conical body, and a cylindrical neck. It is named after the German chemist Emil Erlenmeyer (1825–1909), who created it in 1860. Erlenmeyer flasks have wide bases, with sides that taper upward to a short vertical neck. They may be graduated, and often spots of ground glass or enamel are used where they can be labeled with a pencil. It differs from the beaker in its tapered body and narrow neck. Depending on the application, they may be constructed from glass or plastic, in a wide range of volumes. The mouth of the Erlenmeyer flask may have a beaded lip that can be stopped or covered. Alternatively, the neck may be fitted with ground glass or other connector for use with more specialized stoppers or attachment to other apparatus. A Büchner flask is a common design modification for filtration under vacuum. Uses In chemistry ...

Deformity Type Erlenmeyer Flask
Osteochondrodysplasia is a general term for a disorder of the development (dysplasia) of bone ("osteo") and cartilage ("chondro"). Osteochondrodysplasias are rare diseases. About 1 in 5,000 babies are born with some type of skeletal dysplasia. Nonetheless, if taken collectively, genetic skeletal dysplasias or osteochondrodysplasias comprise a recognizable group of genetically determined disorders with generalized skeletal affection. Osteochondrodysplasias can result in marked functional limitation and even mortality. Osteochondrodysplasias subtypes can overlap in clinical aspects, therefore plain radiography is absolutely necessary to establish an accurate diagnosis. Magnetic resonance imaging can provide further diagnostic insights and guide treatment strategies especially in cases of spinal involvement. Early diagnosis, and timely management of skeletal dysplasia are important to combat functional deterioration. Types Achondroplasia ''Achondroplasia'' is a type of autosomal ...

Friedrich Gustav Carl Emil Erlenmeyer
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. Biography Erlenmeyer was born in Heidelberg, but moved with his family to Munich in 1868. He studied at various universities in Heidelberg, Bonn, Darmstadt and Marburg. He received his Ph.D. in 1888 from the University of Göttingen. 1893 he started working at the University of Strasbourg and from 1907 till his death in 1921 he was working at the kaiserliche biologische Anstallt Dahlem.

Erlenmeyer Rule
In organic chemistry, alkenols (shortened to enols) are a type of reactive structure or intermediate in organic chemistry that is represented as an alkene ( olefin) with a hydroxyl group attached to one end of the alkene double bond (). The terms ''enol'' and ''alkenol'' are portmanteaus deriving from "-ene"/"alkene" and the "-ol" suffix indicating the hydroxyl group of alcohols, dropping the terminal "-e" of the first term. Generation of enols often involves removal of a hydrogen adjacent (α-) to the carbonyl group—i.e., deprotonation, its removal as a proton, . When this proton is not returned at the end of the stepwise process, the result is an anion termed an enolate (see images at right). The enolate structures shown are schematic; a more modern representation considers the molecular orbitals that are formed and occupied by electrons in the enolate. Similarly, generation of the enol often is accompanied by "trapping" or masking of the hydroxy group as an ether, such ...
