Abstract

Amine Alamine 304 dissolved in xylene reacts with hydrochloric acid to form the amine chloride (R₃NH⁺Cl^-) and the amine dichloride (R₃NH₂Cl₂). The former compound was isolated and characterized by chemical analysis, X-ray powder diffraction, infrared spectroscopy and scanning electron microscopy. Lattice parameters of the isolated amine chloride were determined and refined by least-square numerical treatment (monoclinic cell, with a = 29.017(4) Å, b = 14.564(7) Å, c = 5.043(1) Å, b = 95.68(3) ° and V = 2,120 Å³). The amine chloride is a potential anion-exchanger with metals, thus data on the liquid-liquid extraction of Co(II), Au(III) and Pt(IV) are also reported.
