The pK a of protonated triethylamine is 10.75, [4] and it can be used to prepare buffer solutions at that pH. The hydrochloride salt, triethylamine hydrochloride (triethylammonium chloride), is a colorless, odorless, and hygroscopic powder, which decomposes when heated to 261 °C. Triethylamine is soluble in water to the extent of 112.4 g/L at ...

In 1901, Edgar Wedekind published the synthesis of alkyl ketene dimers by the reaction of carboxylic acid chlorides with tertiary amines: [5] [6] RCH 2 COCl + R 3 N → RCH=C=O + R 3 NHCl The molecular weight determined by the early researchers indicated (CH 3) 2 CH=C=O) n where n > 1 for the dehydrohalogenation of isobutyryl chloride with triethylamine.
Triethylaluminium can be formed via several routes. The discovery of an efficient route was a significant technological achievement. The multistep process uses aluminium, hydrogen gas, and ethylene, summarized as follows: [4]
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.

Diethylenetriamine (abbreviated Dien or DETA) and also known as 2,2’-Iminodi(ethylamine) [2]) is an organic compound with the formula HN(CH 2 CH 2 NH 2) 2.This colourless hygroscopic liquid is soluble in water and polar organic solvents, but not simple hydrocarbons.
Beyond its walls in the posh Mayfair district, the booksellers handpick collections of old, new, and out-of-print volumes for private residences, embassies, castles, and ships. “Our Libraries ...
