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 ...
DIPEA is a sterically hindered organic base that is commonly employed as a proton scavenger. Thus, like 2,2,6,6-tetramethylpiperidine and triethylamine, DIPEA is a good base but a poor nucleophile, DIPEA has low solubility in water, which makes it very easily recovered in commercial processes, a combination of properties that makes it a useful organic reagent.
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 ...

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]
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]

Phenylethanolamine (sometimes abbreviated PEOH), or β-hydroxyphenethylamine, is a trace amine with a structure similar to those of other trace phenethylamines as well as the catecholamine neurotransmitters dopamine, norepinephrine, and epinephrine.
