Vulcanization of halogen-containing rubbers with polybismuthiol.

Halogen-containing tetrametallic aluminium alkoxides.

New halogen-containing tetrametallic aluminium alkoxides of formula [Al{(mu-OEt)2AlMeCl}3] ( 2-cis; 2-trans), and [Al{(mu-OEt)2AlBr2}3] ( 4), have been synthesized by combining Al(OEt)3 and Me2AlCl (for 2) or EtAlBr2 (for 4). They were fully characterized by (1H, 27Al) NMR, IR, mp, elemental analysis, and single-crystal X-ray diffractometry. The chloride analogue of 4, [Al{(mu-OEt)2AlCl2}3] ( 3...

Destruction of halogen-containing pesticides by means of detonation combustion

Pesticides that contain a halogen functional group have been destructed by means of detonative combustion. The following compounds were examined: (1) atrazine-2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine-herbicide; (2) bromophos-O,4-bromo-2,5-dichlorophenyl O,O-dimethyl phosphorothioate-insecticide; (3) chloridazon-5-amino-4-chloro-2-phenylopyridazin-3(2H)-one-herbicide; (4) linuron-3-...

Drugs containing halogen atoms: toxicity and lack of toxicity.

John Wiley & Sons Raman spectroscopy of halogen containing carbonates

Raman spectroscopy complimented with infrared spectroscopy has been used to study a series of selected natural halogenated carbonates from different origins including bastnasite, parisite and northupite. The position of CO3 symmetric stretching vibration varies with mineral composition. An additional band for northupite at 1107 cm is observed. Raman spectra of bastnasite, parisite and northupit...
