Triethylamine is prepared by the alkylation of ammonia with ethanol: [10]. 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.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

Triethylenetetramine (TETA and trien), also known as trientine when used medically, is an organic compound with the formula [CH 2 NHCH 2 CH 2 NH 2] 2.The pure free base is a colorless oily liquid, but, like many amines, older samples assume a yellowish color due to impurities resulting from air oxidation.
Like other simple aliphatic amines, ethylamine is a weak base: the pK a of [CH 3 CH 2 NH 3] + has been determined to be 10.8 [8] [9] Ethylamine undergoes the reactions anticipated for a primary alkyl amine, such as acylation and protonation. Reaction with sulfuryl chloride followed by oxidation of the sulfonamide give diethyldiazene, EtN=NEt. [10]
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.
Triethylphosphite is prepared by treating phosphorus trichloride with ethanol in the presence of a base, typically a tertiary amine: [1] PCl 3 + 3 EtOH + 3 R 3 N → P(OEt) 3 + 3 R 3 NH + 3 Cl −. In the absence of the base, the reaction of ethanol and phosphorus trichloride affords diethylphosphite ((EtO) 2 P(O)H). Of the many related ...
