ENMC-2 SENSITIVITY AND DETONATION PARAMETERS OF 4, 6-DIAZIDO-N-NITRO-1, 3, 5-TRIAZIN-2-AMINE Tomáš Musil*, Robert Matyáš*, Ondřej Němec*, Martin Künze* Abstract Highly dense nitrogen-rich compounds are potential high performance energetic materials for use in industrial scene or military. 4,6-Diazido-N-nitro-1,3,5-triazin-2- amine (DANT) is relatively a new substance on which characterization and detonation parameters were tested. The sensitivity of DANT to impact, friction and electric discharge was also determined. Sensitivity to impact is between PETN and RDX, sensitivity to friction is higher as PETN. DANT´s relative strength is 108 % of TNT. We also calculated and measured detonation parameters such as pressure and detonation velocity. Theoretical detonation parameters are 8 205 m.s-1 and 30.3 GPa. Temperature of autoignition is 156 °C. Keywords: 4,6-Diazido-N-nitro-1,3,5-triazin-2-amine; DANT, detonation parameters, sensitivity * Institute of Energetic Materials, Faculty of Chemical Technology, University of Pardubice, Studentska 95, 532 10 Pardubice, Czech Republic.

  • Toxicological Profile for Beryllium
    BERYLLIUM 19 3. HEALTH EFFECTS 3.1 INTRODUCTION The primary purpose of this chapter is to provide public health officials, physicians, toxicologists, and other interested individuals and groups with an overall perspective on the toxicology of beryllium. It contains descriptions and evaluations of toxicological studies and epidemiological investigations and provides conclusions, where possible, on the relevance of toxicity and toxicokinetic data to public health. A glossary and list of acronyms, abbreviations, and symbols can be found at the end of this profile. 3.2 DISCUSSION OF HEALTH EFFECTS BY ROUTE OF EXPOSURE To help public health professionals and others address the needs of persons living or working near hazardous waste sites, the information in this section is organized first by route of exposure (inhalation, oral, and dermal) and then by health effect (death, systemic, immunological, neurological, reproductive, developmental, genotoxic, and carcinogenic effects). These data are discussed in terms of three exposure periods: acute (14 days or less), intermediate (15–364 days), and chronic (365 days or more). Levels of significant exposure for each route and duration are presented in tables and illustrated in figures. The points in the figures showing no-observed-adverse-effect levels (NOAELs) or lowest-observed-adverse-effect levels (LOAELs) reflect the actual doses (levels of exposure) used in the studies. LOAELS have been classified into "less serious" or "serious" effects. "Serious" effects are those that evoke failure in a biological system and can lead to morbidity or mortality (e.g., acute respiratory distress or death). "Less serious" effects are those that are not expected to cause significant dysfunction or death, or those whose significance to the organism is not entirely clear.

  • Working with Hazardous Chemicals
    A Publication of Reliable Methods for the Preparation of Organic Compounds Working with Hazardous Chemicals The procedures in Organic Syntheses are intended for use only by persons with proper training in experimental organic chemistry. All hazardous materials should be handled using the standard procedures for work with chemicals described in references such as "Prudent Practices in the Laboratory" (The National Academies Press, Washington, D.C., 2011; the full text can be accessed free of charge at http://www.nap.edu/catalog.php?record_id=12654). All chemical waste should be disposed of in accordance with local regulations. For general guidelines for the management of chemical waste, see Chapter 8 of Prudent Practices. In some articles in Organic Syntheses, chemical-specific hazards are highlighted in red “Caution Notes” within a procedure. It is important to recognize that the absence of a caution note does not imply that no significant hazards are associated with the chemicals involved in that procedure. Prior to performing a reaction, a thorough risk assessment should be carried out that includes a review of the potential hazards associated with each chemical and experimental operation on the scale that is planned for the procedure. Guidelines for carrying out a risk assessment and for analyzing the hazards associated with chemicals can be found in Chapter 4 of Prudent Practices. The procedures described in Organic Syntheses are provided as published and are conducted at one's own risk. Organic Syntheses, Inc., its Editors, and its Board of Directors do not warrant or guarantee the safety of individuals using these procedures and hereby disclaim any liability for any injuries or damages claimed to have resulted from or related in any way to the procedures herein.

  • Particularly Hazardous Substances
    Particularly Hazardous Substances In its Laboratory Standard, OSHA requires the establishment of additional protections for persons working with "Particularly Hazardous Substances" (PHS). OSHA defines these materials as "select" carcinogens, reproductive toxins and acutely toxic materials. Should you wish to add: explosive, violently reactive, pyrophoric and water-reactve materials to this category, the information is included. Carbon nanotubes have also been added due to their suspected carcinogenic properties. This table is designed to assist the laboratory in the identification of PHS, although it is not definitively conclusive or entirely comprehensive. *Notes on the proper use of this table appear on page 12. 1 6 5 2 3 4 Substance CAS National Toxicity National Program Carcinogen Toxin Acute Regulated OSHA Carcinogen Group IARC Carcinogen Toxin Reproductive Violently Reactive/ Explosive/Peroxide Forming/Pyrophoric A-a-C(2-Amino-9H-pyrido[2,3,b]indole) 2648-68-5 2B Acetal 105-57-7 yes Acetaldehyde 75-07-0 NTP AT 2B Acrolein (2-Propenal) 107-02-8 AT Acetamide 126850-14-4 2B 2-Acetylaminofluorene 53-96-3 NTP ORC Acrylamide 79-06-6 NTP 2B Acrylyl Chloride 814-68-6 AT Acrylonitrile 107-13-1 NTP ORC 2B Adriamycin 23214-92-8 NTP 2A Aflatoxins 1402-68-2 NTP 1 Allylamine 107-11-9 AT Alkylaluminums varies AT Allyl Chloride 107-05-1 AT ortho-Aminoazotoluene 97-56-3 NTP 2B para-aminoazobenzene 60-09-3 2B 4-Aminobiphenyl 92-67-1 NTP ORC 1 1-Amino-2-Methylanthraquinone 82-28-0 NTP (2-Amino-6-methyldipyrido[1,2-a:3’,2’-d]imidazole) 67730-11-4 2B

  • Beryllium and Beryllium Compounds
    BERYLLIUM AND BERYLLIUM COMPOUNDS Beryllium and beryllium compounds were considered by previous IARC Working Groups in 1971, 1979, 1987, and 1993 (IARC, 1972, 1980, 1987, 1993). Since that time, new data have become available, these have been incorporated in the Monograph, and taken into consid- eration in the present evaluation. 1.
