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 ...
Tetraethylammonium (TEA) is a quaternary ammonium cation with the chemical formula [Et 4 N] +, consisting of four ethyl groups (−C 2 H 5, denoted Et) attached to a central nitrogen atom. It is a counterion used in the research laboratory to prepare lipophilic salts of inorganic anions.
The Schotten–Baumann reaction is a method to synthesize amides from amines and acid chlorides: . An example of a Schotten-Baumann reaction. Benzylamine reacts with acetyl chloride under Schotten-Baumann conditions to form N-benzylacetamide.
CH 3 (CH 2) 7 CH=CH(CH 2) 7 CO 2 H} + 4 O 3 → HO 2 C(CH 2) 7 CO 2 H} + CH 3 (CH 2) 7 CO 2 H. Erucic acid is a precursor to brassylic acid, a C13-dicarboxylic acid that is used to make specialty polyamides and polyesters. The conversion entails ozonolysis, which selectively cleaves the C=C bond in erucic acid: [21]
The bicarbonate ion (hydrogencarbonate ion) is an anion with the empirical formula HCO − 3 and a molecular mass of 61.01 daltons; it consists of one central carbon atom surrounded by three oxygen atoms in a trigonal planar arrangement, with a hydrogen atom attached to one of the oxygens.
