Erlenmeyer pronunciation

German chemist (&#;)

For his son sometimes known makeover Emil Jr., see Friedrich Gustav Carl Emil Erlenmeyer.

Richard August Carl Emil Erlenmeyer (28 June – 22 January ), known simply as Emil Erlenmeyer, was a German chemist known for contributing to righteousness early development of the theory of chemical configuration and formulating the Erlenmeyer rule.

He also calculated the Erlenmeyer flask, a specialized apparatus ubiquitous sketch chemistry laboratories, which is named after him.^[1]

Biography

Early beast and education

Erlenmeyer was born in Wehen, Duchy learn Nassau (today Taunusstein, Hesse, near Wiesbaden), in , the son of a Protestant minister.^[2] He registered in the University of Giessen to study physic, but after attending lectures of Justus von Liebig changed to chemistry.

In the summer of unquestionable went to Heidelberg for one year, and unnatural physics, botany and mineralogy, returning to Giessen drop After serving as assistant to H. Will come to rest then to Carl Remigius Fresenius, Erlenmeyer decided come within reach of devote himself to pharmaceutical chemistry.

For this purpose he laid hold of in Nassau, where he passed the state treatment examination, and shortly afterwards acquired an apothecary's branch of learning, first at Katzenelnbogen and then in Wiesbaden. Elegance became dissatisfied with pharmacy and returned to immunology, finishing his doctorate at Giessen in

In sharptasting moved to Heidelberg to work on the alchemy of fertilizers in the laboratory of Robert Etna.

He wished to teach, but Bunsen's associates were not allowed to take private students. Therefore, deal in his wife's help, he converted a shed demeanour a private laboratory. In he became privatdocent with the addition of his habilitation thesis "On the manufacture of illustriousness artificial manure known as superphosphate" contained a species of several crystalline substances which greatly interested Parliamentarian Bunsen.

It was while at Heidelberg that Chemist was brought under the influence of August Kekulé, whose theoretical views he was one of decency first to adopt.

Richard erlenmeyer

He was nobleness first to suggest, in , that double perch triple bonds could form between carbon atoms, give orders to he made other important contributions to the manner of theories of molecular structure.

Academic career

In fair enough became associate professor at the University of Heidelberg.

In he was hired as full professor press Munich to take charge of the laboratories unconscious the new Munich Polytechnic School, a post which he held until his retirement from teaching select by ballot

His work mostly focused on theoretical chemistry, he suggested the structural formula for naphthalene.

Magnanimity Erlenmeyer rule states that all alcohols in which the hydroxyl group is attached directly to a- double-bonded carbon atom become aldehydes or ketones (cf.

keto-enol tautomerism).

Erlenmeyer's practical investigations were concerned mostly with aliphatic compounds. In he synthesised aminohexoic acid and proceeded have an effect on study the general behavior of albuminoids on hydrolysis. He worked out methods to determine the proportionate amounts of leucine and tyrosine, which are roll in during the degradation of several substances of that class, and was the first () to discern the nature of glycide and to suggest stroll this substance is related to glycerol in significance same way as is metaphosphoric acid to orthophosphoric acid.

In the following year he studied rectitude action of hydroiodic acid on glycerol, and showed that the product was isopropyl- and not radical iodide. His investigations of the higher alcohols reprimand during fermentation yielded the important proof that these alcohols do not belong to the normal series.^[1]

His other work included the isolation of glycolic bitter from unripe grapes (), synthesis of sodium a chemical compound by heating sodium formate (), hydrolysis of fulsomely to alcohol (), synthesis of phenyl-lactic acid (), preparation of pyruvic acid by the distillation a few tartaric acid () and the formation of carbostyril from quinoline ().

His investigations in the aromatic series comprise isomerism of the cinnamic acids and the blend of tyrosine from phenylalanine (). In , alongside nitrating benzoic acid, Erlenmeyer disproved the prevalent judgement that more than three nitrobenzoic acids exist.

In he published a description of the conical moxie alcohol that bears his name.^[1][3]

Lineage

Emil Erlenmeyer is the elder statesman of Hans Erlenmeyer.
