专利号:US-7279572-B2 优先权日:2003-05-22 标题:Process for the 2-stage synthesis of hexanitrohexaazaisowurtzitane starting from a primary amine 发明人:CAGNON GUY; ECK GENEVIEVE; HERVE GREGOIRE; JACOB GUY 权利人:SNPE MATERIAUX ENERGETIQUES 摘要:A subject-matter of the present invention is a novel process for the synthesis of hexanitrohexaazaisowurtzitane (HNIW), a compound of use as energetic filler in powders, propellants and explosives. n This process comprises a first stage of reaction of an α,β-dicarbonyl derivative with a primary amine which makes it possible to form a hexasubstituted hexaazaisowurtzitane derivative. n The HNIW is subsequently obtained directly, in a single reaction stage, by nitration of the hexasubstituted hexaazaisowurtzitane derivative. n This process, in only 2 stages starting from a primary amine, is particularly simple and inexpensive.

专利号:US-7101955-B1 优先权日:1998-11-12 标题:Synthesis of energetic thermoplastic elastomers containing both polyoxirane and polyoxetane blocks 发明人:SANDERSON ANDREW J; EDWARDS WAYNE; CANNIZZO LOUIS F; WARDLE ROBERT B 权利人:ALLIANT TECHSYSTEMS INC 摘要:This thermoplastic elastomer is present in a substantially solid state suitable for use as a binder for a propellant, explosive, and/or gas generant of a supplemental restraint system. The thermoplastic elastomer is formed from a composition including A blocks which are crystalline at temperatures below about 75° C. and B blocks which are amorphous at temperatures above about −20° C. The A blocks are derived from oxetane derivatives and the B blocks are derived from oxiranes and derivatives thereof. The A blocks and B-blocks are end-capped with a diisocyanate having a first isocyanate moiety that is substantially more reactive with the terminal groups of the blocks than the second isocyanate moiety, whereby the more reactive first isocyanate moiety is capable of reacting with the terminal groups of the blocks, leaving the less reactive second isocyanate moiety free and unreacted. The end-capped A blocks and the end-capped B blocks are linked together with a linking compound having two isocyanate-reactive groups which are sufficiently unhindered to react with the free and unreacted isocyanate moieties of the end-capped polymers.
专利号:US-10119953-B1 优先权日:2015-03-20 标 题 :Metal chalcogenide quantum dots for the detection of nitroaromatic chemicals 发明人:BACA ALFRED J; MEYLEMANS HEATHER A; CAMBREA LEE R; BALDWIN LAWRENCE 权利人:US NAVY; US NAVY 摘要:The synthesis of AgInS 2 based quantum dots and their use as fluorometric probes for the selective detection of nitroaromatic explosive chemicals, without the use of ligands specific to nitroaromatic explosive chemicals. These quantum dots allow the detection of nitroaromatic explosive molecules by eye. The present invention also represents a simple patterning method for quantum dots on substrates, including low cost filter paper. The ease of fabrication, use of less toxic materials, and the selectivity to nitroaromatic explosive chemicals results in a practical solution to the development of a portable fluorescent probe based on quantum dots for the detection of nitroaromatic explosive chemicals.
