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 ...
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. [2]
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(NH 3 (in which the bond angle between the nitrogen and hydrogen is 170°), wherein one or more hydrogen atoms have been replaced by a substituent such as an ...
Free base (freebase, free-base) is a descriptor for the neutral form of an amine commonly used in reference to illicit drugs. The amine is often an alkaloid , such as nicotine , cocaine , morphine , and ephedrine , or derivatives thereof.
Ethanolamine (2-aminoethanol, monoethanolamine, ETA, or MEA) is a naturally occurring organic chemical compound with the formula HOCH 2 CH 2 NH 2 or C 2 H 7 NO. [8] The molecule is bifunctional, containing both a primary amine and a primary alcohol.
Emergence of Bio-Based Alternatives: Research into bio-based amines presents a promising area for market expansion. Companies are exploring bio-based production methods to enhance sustainability. New Agrochemical Formulations: The agrochemical industry is witnessing innovations in herbicide formulations, leading to higher ethylamine demand. For ...
Triethylamine is commonly employed in organic synthesis as a base. For example, it is commonly used as a base during the preparation of esters and amides from acyl chlorides . [ 15 ] Such reactions lead to the production of hydrogen chloride which combines with triethylamine to form the salt triethylamine hydrochloride, commonly called ...
The Schiff base is an electrophile which reacts in a second step in an electrophilic addition with an enol formed from a carbonyl compound containing an acidic alpha-proton. The Mannich reaction is a condensation reaction. [4]: 140 In the Mannich reaction, primary or secondary amines or ammonia react with formaldehyde to form a Schiff base ...
