Isolation and characterization of the tertiary amine Alamine 304 hydrochloride. Its application on the extraction of Co(II), Au(III) and Pt(IV)

Amine Alamine 304 dissolved in xylene reacts with hydrochloric acid to form the amine chloride (R3NH+Cl+) and the amine dichloride (R3NH2Cl2). The for mer compound was isolated and characterised by chemical analysis, X-ray pow der diffraction, infrared spectroscopy and scanning electron microscopy. La ttice parameters of the isolated amine chloride were determined and refined by least-square numerical treatment (monoclinic cell, with a = 29.017 Angs trom, b = 14.564(7) Angstrom, c = 5.043 Angstrom, b = 95.68(3) degrees and V = 2,120 Angstrom(3)). The amine chloride is a potential anion-exchanger w ith metals, thus data on the liquid-liquid extraction of Co(II), Au(III) an d Pt(IV) are also reported.
