A1 - Wehrstedt, Klaus-Dieter T1 - Taming the silicon tetraazide beast N2 - Highly energetic silicon tetraazide 1 is synthesized safely in high yield and high purity. The compound is prepared as a solution in benzene which allows it to be handled safely. Stable Lewis base adducts of Si(N3)4 (e.g. 2) are also prepared by treatment of either Si(N3)4 or the di­sodium salt of hexaazidosilicate (3) with Lewis bases (2,2-bipyridine or 1,10-phenanthroline). Unlike Si(N3)4 the Lewis base adduct 2 is thermally stable and does not decompose below 265 °C. The decomposition is very energetic (ΔHd = -2.4 kJg-1) which means 2 and related Lewis base ­adducts could replace environmentally harmful Pb(N3)4 used as primary explosive.

N2 - IGUS is the International Group of Experts on the Explosion Risks of Unstable Substances. IGUS was established in 1962 with the objective to harmonize test methods used by different countries to identify and quantify the explosive properties of unstable materials. Over the years, IGUS has continued to offer scientists, who are advisers to their governments, and others, a forum to exchange data and information. The Energetic and Oxidizing Substances (EOS) working group as a sub-group of IGUS is dealing with test methods, Classification and safety aspects relating to organic peroxides, self-reactive substances and other energetic substances, fertilizers, ammonium nitrate and oxidizers. The EOS working group holds an annual meeting alternating between Europe, the United States and Japan. The 2011 meeting took place from the 27th to the 29th of April 2011 at the Madison Hotel in Washington, D. C. The meeting was hosted by the Organic Peroxide Producers Safety Division (OPPSD) of the Society of Plastics Industry, Inc. (SPI). This was the fourth EOS meeting held in the USA since 1994. Of particular importance is the fact that 39 colleagues from authorities, universities, research institutes and industries attended the meeting. The delegates came from USA, Canada, China, France, The Netherlands, Norway, Sweden, Italy, Japan, United Kingdom and Germany. This confirms the breadth and scope of this forum and the value the participants associate with being able to contact other colleagues from around the world enabling the effective exchange of scientific results and discussion on the wide-ranging Problems concerning energetic and oxidizing materials.
