nh 3 + 3 c 2 h 5 oh → n(c 2 h 5) 3 + 3 h 2 o 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.
Triethanolamine, or TEOA, is an organic compound with the chemical formula N(CH 2 CH 2 OH) 3. It is a colourless, viscous liquid. It is both a tertiary amine and a triol. A triol is a molecule with three alcohol groups. Approximately 150,000 tonnes were produced in 1999. [3] It is a colourless compound although samples may appear yellow because ...
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.
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.

In organic chemistry, the Swern oxidation, named after Daniel Swern, is a chemical reaction whereby a primary or secondary alcohol (−OH) is oxidized to an aldehyde (−CH=O) or ketone (>C=O) using oxalyl chloride, dimethyl sulfoxide (DMSO) and an organic base, such as triethylamine. [1] [2] [3] It is one of the many oxidation reactions ...
The bicarbonate buffer system is an acid-base homeostatic mechanism involving the balance of carbonic acid (H 2 CO 3), bicarbonate ion (HCO − 3 ), and carbon dioxide (CO 2 ) in order to maintain pH in the blood and duodenum , among other tissues, to support proper metabolic function. [ 1 ]
The parameter standard bicarbonate concentration (SBC e) is the bicarbonate concentration in the blood at a P a CO 2 of 40 mmHg (5.33 kPa), full oxygen saturation and 36 °C. [13] Reference ranges for blood tests, comparing blood content of bicarbonate (shown in blue at right) with other constituents.
