| | 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 and precious metals. | | 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. | | 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.] |
