What are the applications of Application

Trioctylamine 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.]
