DOCUMENT TYPE: Conference CA Section: 36 (Plastics Manufacture and Processing) The title anion exchangers (AN-221 [9084-87-1], AN-511 [66106-54-5], and AN-521 [66106-55-6]) are prepd. by aminating chloromethylated divinylbenzene-styrene copolymer with NH2CH2CH2NH2 (I) [107-15-3], (NH2CH2CH2)2NH (II) [111-40-0] NH2(CH2CH2NH)2CH2CH2NH2 (III) [112-24-3], or (NH2CH2CH2)3N (IV) [4097-89-6]. The exchangers had exchange capacity ￡8 mg-equiv./g, sp. surface 40-120 m2/g, and total pore vol. 0.2-0.9 cm3/g. Anion exchangers prepd. with II, III, or IV aminating agents had better kinetic properties than those prepd. with I.

DOCUMENT TYPE: Journal CA Section: 78 (Inorganic Chemicals and Reactions) Section cross-reference(s): 75 [H3tren]×(AlF6)×H2O, [H3tren]×(AlF6)×HF and [H4tren]×(MF6)×(F) (M = Al, Fe; tren = tris(2-aminoethyl)amine), were obtained by hydrothermal technique and microwave heating in the (Al(OH)3,FeF3)-tren-(HF/H2O)-EtOH system. Structure detns. were performed from single crystal x-ray diffraction data. All phases are built up from (MF6)3- anions linked by H bonds to [H3tren]3+ or [H4tren]4+ cations and to H2O or HF mols.Several substances with their cas registry numbers 4097-89-6 and 7783-50-8 may be metioned in this study. or isolated fluoride anions. [H3tren]3+ and [H4tren]4+ cations adopt a spider shape configuration. Surprisingly, the HF mol. is strongly H bonded with one F- ion of the AlF6 octahedron (d F×××F = 2.38 ?) in [H3tren]×(AlF6)×HF while isolated F- ion is weakly coordinated by three H atoms in [H4tren]×(MF6)×(F). The evolution of the formulations, from [H3tren]×(AlF6)×H2O to [H3tren]×(AlF6)×HF and to [H4tren]×(MF6)×(F) (M = Al, Fe), is linked with the increase of the HF content of the starting soln. The vols. per formula unit decrease from 321.3(1) ?3 and 320.6(1) ?3 in [H3tren]×(AlF6)×H2O and [H3tren]×(AlF6)×HF, resp., to 298.5(4) ?3 in [H4tren]×(AlF6)×(F). .
