Xylitol pentanitrate (XPN) is a nitrated ester primary explosive [3] [4] first synthesized in 1891 by Gabriel Bertrand. [5] [6] Law enforcement has taken an interest in XPN along with erythritol tetranitrate (ETN) and pentaerythritol tetranitrate (PETN) due to their ease of synthesis, which makes them accessible to amateur chemists and terrorists.
front cover G1 1930. This is the Group G series List of the United States military vehicles by (Ordnance) supply catalog designation, – one of the alpha-numeric "standard nomenclature lists" (SNL) that were part of the overall list of the United States Army weapons by supply catalog designation, a supply catalog that was used by the United States Army Ordnance Department / Ordnance Corps as ...
6 Na + 3 C 6 H 5 Cl + SbCl 3 → (C 6 H 5) 3 Sb + 6 NaCl. In an alternative method, phenylmagnesium bromide is treated with SbCl 3. [5] Upon treatment with antimony trichloride, triphenylstibine undergoes a redistribution reaction: [6] Sb(C 6 H 5) 3 + 2SbCl 3 → 3Sb(C 6 H 5)Cl 2. Stiboranes can be synthesised from triphenylstibine by halogenation:
