Download or read book Exploratory Analysis of Vapor Impurities from TNT RDX and Composition B written by and published by . This book was released on 1973 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vapors collected from TNT, RDX and composition B explosives maintained at 25C and 70C were analyzed using a gas chromatographic/mass spectrometric technique to identify the most prominent vapor components. A gas chromatograph equipped with electron capture and flame ionization detectors also was used to screen vapors for components present at concentrations below the sensitivity of the GC/MS. Cyclohexanone which could have significance in development of an explosive or mine detector was identified in vapors from RDX and composition B. Water vapor, carbon dioxide, probably nitrous oxide and a number of unidentified compounds were evolved from all samples. It may be possible to identify these unknown compounds present at trace levels, but extreme analytical care and precaution to avoid contamination would be required. In this regard, differentiation between compounds which are incorporated into the explosive matrix during manufacturing and those which are adsorbed from air by the explosive at a later time is also required.

Download or read book Analysis of Vapors Emitted from Military Mines written by and published by . This book was released on 1973 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vapor evolving from several types of intact military mines was analyzed using gas chromatography and gas chromatography/mass spectroscopy. Cyclohexanone was positively identified in the vapor from M15 (metallic) and M19 (nonmetallic) antitank mines. This compound originates from composition B, the explosive used in these mines. Acetone, toluene and an unknown organo-silicon compound were identified and are attributable to the nonmetallic mine casings. Although positive mass spectral identification is lacking, chromatographic data obtained using an electron capture detector indicated that 2, 4, 6 trinitrotoluene was detected in the vapor from the M16 (metallic) antipersonnel mines which are loaded with TNT.

Available in PDF, EPUB and Kindle. Book excerpt: Atmospheric samples were taken at the soil surface above field- emplaced M-15 and M-19 antitank mines and military explosive Composition-B. These samples were analyzed to determine if trace chemicals generated by the explosive material are detectable. Cyclohexanone was positively identified and is attributable to the explosive. Calculations were made, based on the amount of cyclohexanone found, to approximate its flux rate through the surface.
