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 ...
Tris(2-aminoethyl)amine is the organic compound with the formula N(CH 2 CH 2 NH 2) 3.This colourless liquid is soluble in water and is highly basic, consisting of a tertiary amine center and three pendant primary amine groups.
Ethylamine is produced on a large scale by two processes. Most commonly ethanol and ammonia are combined in the presence of an oxide catalyst: CH 3 CH 2 OH + NH 3 → CH 3 CH 2 NH 2 + H 2 O. In this reaction, ethylamine is coproduced together with diethylamine and triethylamine.
Before 1945, only a few hundred kilograms of germanium were produced in smelters each year, but by the end of the 1950s, the annual worldwide production had reached 40 metric tons (44 short tons). [29] The development of the germanium transistor in 1948 [30] opened the door to countless applications of solid state electronics. [31]
Examples include: Stereoselective formation of (Z)-diiodoalkenes by treatment of alkynes with ICl in the presence of tetraethylammonium iodide. [4]2-Hydroxyethylation (attachment of −CH 2 −CH 2 −OH) by ethylene carbonate of carboxylic acids and certain heterocycles bearing an acidic N-H.

Triethylaluminium ignites on contact with air and will ignite and/or decompose on contact with water, and with any other oxidizer [13] —it is one of the few substances sufficiently pyrophoric to ignite on contact with cryogenic liquid oxygen. The enthalpy of combustion, Δ c H°, is –5105.70 ± 2.90 kJ/mol [14] (–22.36 kJ/g).
Triethanolamine is used primarily in making surfactants, such as for emulsifier.It is a common ingredient in formulations used for both industrial and consumer products. The triethanolamine neutralizes fatty acids, adjusts and buffers the pH, and solubilizes oils and other ingredients that are not completely soluble in wate
