Identification of α-Chloro-2,2′,4,4′,6,6′-Hexanitrobibenzyl as an Impurity in Hexanitrostilbene

摘要

The final intermediate in the Shipp synthesis of 2,2′,4,4′,6,6′-hexanitrostilbene (HNS) from TNT, α-chloro-2,2′,4,4′,6,6′-hexanitrobibenzyl, has been extracted and characterized by nuclear magnetic resonance (NMR) spectroscopy, chlorine elemental analysis, and high-performance liquid chromatography (HPLC). It has also been shown that digestion in NMP of HNS containing α-chlorohexanitrobibenzyl generates another chlorine-containing by-product, 2-chloro-2′,4,4′,6,6′-pentanitrostilbene. This too has been characterized by NMR spectroscopy, chlorine elemental analysis, and HPLC.View full textDownload full textKeywordsα-chloro-2,2′,4,4′,6,6′-hexanitrobibenzyl, 2,2′,4,4′,6,6′-hexanitrostilbene (HNS), 2-chloro-2′,4,4′,6,6′-pentanitrostilbeneRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/07370650902961258
