Ethylamine, also known as ethanamine, is an organic compound with the formula CH 3 CH 2 NH 2. This colourless gas has a strong ammonia-like odor. It condenses just below room temperature to a liquid miscible with virtually all solvents. It is a nucleophilic base, as is typical for amines. Ethylamine is widely used in chemical industry and ...
Amine. In chemistry, amines (/ ə ˈ m iː n, ˈ æ m iː n /, [1] [2] UK also / ˈ eɪ m iː n / [3]) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3 (in which the bond angle between the nitrogen and hydrogen is 170°), wherein one or more hydrogen atoms have been replaced by a substituent such as an ...
In all these examples, stoichiometric base is needed to convert the amine hydrochloride to free amines. In the monoethanolamine route, monoethanolamine reacts with ammonia, catalyzed by transition metal catalysts. This process is reported to generate more cyclic compounds than the ethylene dichloride route.
Strong bases catalyze hydroamination, an example being the ethylation of piperidine using ethene: [27] Hydroamination of ethene with piperidine proceeds with no transition metal catalyst, but requires a strong base. Such base catalyzed reactions proceed well with ethene but higher alkenes are less reactive.
Ethylenediamine (abbreviated as en when a ligand) is the organic compound with the formula C 2 H 4 (NH 2) 2.This colorless liquid with an ammonia-like odor is a basic amine.It is a widely used building block in chemical synthesis, with approximately 500,000 tonnes produced in 1998. [6]
A major factor in determining the reactivity of acyl derivatives is leaving group ability, which is related to acidity. Weak bases are better leaving groups than strong bases; a species with a strong conjugate acid (e.g. hydrochloric acid) will be a better leaving group than a species with a weak conjugate acid (e.g. acetic acid).
A strong base is a basic chemical compound that can remove a proton (H +) from (or deprotonate) a molecule of even a very weak acid (such as water) in an acid–base reaction. Common examples of strong bases include hydroxides of alkali metals and alkaline earth metals, like NaOH and Ca(OH) 2, respectively. Due to their low solubility, some ...
