Tri-n-octylamine Usage And Synthesis

Chemical Properties

Tri-n-octylamine is clear colorless liquid

Uses

Tri-n-octylamine is used as an extractant for organic acids like trichloroacetic acid, succinic acid, acetic acid and precious metals. It is also used as a solvent and an intermediate in the manufacture of pharmaceuticals. Further, it is employed in the preparation of quaternary ammonium compounds, agrochemicals, surfactants, lubricant additives, corrosion inhibitors, vulcanization accelerators and dyes.

Uses

Trioctylamine is used as an extractant for organic acids (such as TCA, succinic acid, and acetic acid), and precious metals.

Uses

Tri-n-octylamine is used as an extractant for organic acids and precious metals.

Purification Methods

It is converted to the amine hydrochloride etherate which is recrystallised four times from diethyl ether at -30o (see below). Neutralisation of this salt regenerates the free amine which distil under high vacuum. [Wilson & Wogman J Phys Chem 66 1552 1962.] Distil the amine at 1-2mm pressure. [Beilstein 4 H 196, 4 III 382, 4 IV 754.]
