Determination of Azides in Organic Solvents.

Abstract

cylinder is preferred. It was necessary to bleed the cylinder at 3 to 4 ml. per minute for 2 to 3 days before good microbubbles could be obtained. The

New potentiometric transducer based on a Mn(II) [2-formylquinoline thiosemicarbazone] complex for static and hydrodynamic assessment of azides

“…Among these approaches are: redox titrimetry [5], electron paramagnetic resonance [6], gasometry [7], spectrometry [8,9], cyclic voltammetry [10], amperometry [11], polarography [12] and chromatography [13][14][15]. Most of these methods require expensive instrumentation, rather complicated techniques, and/or sample pretreatments.…”

Determination of Primary Explosive Azides in Environmental Samples by Sequential Injection Amperometry

“…1 Although the majority of the research in the area of determinations of trace concentrations of explosives has focused on secondary explosives, there have been a few reports of methods for the determination of azide (from lead or sodium azide). Instrumental methods of analysis (spectrophotometric, chromatographic and electrochemical methods) have supplanted cerium 2 and other oxidation-reduction titrimetric methods.…”

Reactions of ceric ammonium nitrate: I. with substituted cycloheptatrienes, II. with diazoalkanes, III. with sodium azide and olefins

“…The evidence for the oxidation of azide ion to nitrogen has been collected (115^ 114) for many years. Potassium chlorate (115)3 manganese dioxide {113), potassium perman ganate (ll5)i hypohalous acids (I15)j nitrous acid (112,115,116), iodine (II5, 117, II8), peroxides (119), nitrosyl ion (120), chromate ion (121), and eerie salts (115,(122)(123)(124)(125)(126) have been shown to decompose metallic azides to nitrogen.…”

“…Of these, eerie salts affect decomposition most completely and the oxidation in fact has been used as an analytical method for the determination of azide ion (122), The mechanisms of the decompositions have not in general been studied in great detail (except for iodine, which is not an oxidation at all) but for eerie salts the azido radical has been suggested as an intermediate (115):…”
