Winter for taking me into Winter lab, which was similar to a second home for me throughout the phD program. His guidance and support as my advisor at Wayne State University allowed me to progress rapidly and successfully. I have obtained numerous synthetic, technical, writing, and presentation skills that are invaluable for my future career while I was in Winter lab. I am also indebted to Professor Charles H. Winter for the confidence that he built in me to push forward by encouraging me all throughout. I am extremely grateful for the wonderful collaboration we had with Prof. Thomas M. Klapötke, Ludwig-Maximilians University, Munich, Germany. The syntheses and standard sensitivity measurements carried out by Benedikt Stiasny and the energetic performance calculations carried out by Dr. Jörg Stierstorfer have completed the research study of peroxo-based compounds for my PhD. I greatly appreciate their hard work and time spent on research, discussions via e-mail, and preparation of manuscripts. I am grateful to my committee members, Prof. James H. Rigby, Dr. Stanislav Groysman, and Dr. Charles L. Dezelah, for their valuable comments and suggestions on my dissertation. I thank Dr. Stanislav Groysman also for allowing me to use the IR spectrometer in his lab. It was a great pleasure to work with the crystallography expert Dr. Philip D. Martin as he was extremely nice to me whenever I brought down a crystal to place in the diffractometer. I am grateful for all the X-ray crystal structures he solved and for his assistance with cif files in the preparation of manuscripts. I would also like to thank Dr. iii Bashar Ksebati and Dr. Yuriy Danylyuk for assisting me with NMR and mass spectrometry, respectively. I am thankful to Nestor Ocampo for his support on software or hardware issues. I appreciate the assistance of the science stores and the non- academic staff members in various ways throughout the PhD program. I would like to pay my gratitude to the past and present Winter lab members who were there while I was in the PhD program for the friendly working environment. I was happy to get involved in all the long chemistry discussions we had, especially with Joseph P. Klesko. Groysman, Brock, and Verani lab members were also always willing to assist me whenever I was in need and I am sincerely grateful for all of their support and friendship. I am extremely fortunate to have two wonderful parents who have dedicated their life for me and my siblings and I am unable to express my gratitude in words for all they have done for me. I am what I am today because of my loving parents. My husband, G. H. Layan Savithra has been the man in my life who protected, cared for, and supported me for more than a decade. The B.S. special degree program in chemistry of University of Colombo was an intense program that brought us together and we were able to push through the hard work ending up as the two top students of our batch. Not only had I learned to love chemistry, but also my path towards PhD in chemistry was opened up because of Layan who was an extremely talented student. I am extremely grateful for all he has done. Last but not least my son, Senuk Y. Savithra is the greatest inspiration I have that keeps me pushing forward no matter what comes in the way. iv TABLE OF CONTENTS DEDICATION .................................................................................................................ii ACKNOWLEDGMENTS ............................................................................................... iii LIST OF TABLES ....................................................................................................... viii LIST OF FIGURES ........................................................................................................xi LIST OF SCHEMES .................................................................................................... xvi LIST OF ABBREVIATIONS ....................................................................................... xvii CHAPTER 1 – Introduction ......................................................................................... 1 1.1 High Energy Density Materials (HEDMs) ................................................. 1 1.2 Deflagration and Detonation .................................................................... 5 1.3 Design of HEDMs .................................................................................... 7 1.4 Sensitivity and Energetic Performance Tests and Calculations ............. 12 1.5 Peroxo-Based Oxygen-Rich Compounds for Use as Greener HEDMs .. 15 1.6 Thesis Problem ...................................................................................... 37 CHAPTER 2 – Synthesis, Characterization, and Study of the Sensitivities and Energetic Properties of tert -Butyl Peroxides ..................................... 39 2.1 Introduction ............................................................................................ 39 2.2 Results and Discussion .......................................................................... 42 2.3 Conclusion ............................................................................................. 59 2.4 Experimental Section ............................................................................. 60 CHAPTER 3 – Synthesis, Characterization, and Study of Surprisingly Highly Energetic and Low Sensitivity tert -Butyl Peroxy Esters with Low Oxygen and Nitrogen Contents ............................................................ 69 v 3.1 Introduction ............................................................................................ 69 3.2 Results and Discussion .......................................................................... 72 3.3 Conclusion ............................................................................................. 99 3.4 Experimental Section ............................................................................ 100 CHAPTER 4 – Synthesis, Characterization, and Study of Oxygen-Rich Geminal Hydroperoxides with Impressive Detonation Performances and Practically Useful Sensitivities ........................................................... 108 4.1 Introduction ........................................................................................... 108 4.2 Results and Discussion ......................................................................... 111 4.3 Conclusion ............................................................................................ 136 4.4 Experimental Section ............................................................................ 137 CHAPTER 5 − Tuning the Impact and Friction Sensitivities and Energetic Performances of a Series of Well-Characterized Cyclic Hydroperoxy Compounds ................................................................... 148 5.1 Introduction ........................................................................................... 148 5.2 Results and Discussion ......................................................................... 152 5.3 Conclusion ............................................................................................ 190 5.4 Experimental Section ............................................................................ 191 CHAPTER 6 − Synthesis, Characterization, and Study of Highly Energetic Peroxy Acids with Surprisingly Low Impact and Friction Sensitivities ............................................................................................ 201 6.1 Introduction ........................................................................................... 201 6.2 Results and Discussion ......................................................................... 204 vi 6.3 Conclusion ............................................................................................ 225 6.4 Experimental Section ...........................................................................

  • Chapter 4: HAZARD COMMUNICATION
    Chapter 4: HAZARD COMMUNICATION The text of this chapter represents the agreement reached on a harmonised hazard communication system as part of the work on the GHS, with minor editorial changes. Additional explanatory text has been added in some sections in order to provide guidance for the reader on how to interpret the GHS agreed text. Where this is the case, the text is italicised and placed in a box to differentiate it from the agreed GHS text. OBJECTIVES AND SCOPE 1. One of the objective of the work on the GHS has been the development of a harmonised hazard communication system including labelling, safety data sheets and easily understandable symbols, based on the classification criteria developed by the focal points within the IOMC Co-ordinating Group for the Harmonisation of Chemical Classifications Systems, CG/HCCS. This work has been carried out under the auspices of the ILO, by the ILO Working Group on Hazard Communication. The specific Terms of Reference and Membership of the Working Group are provided in Annex 1. In addition the principles contained in the IOMC CG/HCCS Terms of Reference and the document “Description and Further Clarification of the Anticipated Application of the GHS (also referred to as “The Scope Document”) also applied to the work on harmonisation of hazard communication (see Chapter 2). Application of the Harmonised Hazard Communication System 2.The harmonised system for hazard communication includes the appropriate labelling tools to convey information about each of the hazard classes and categories in the GHS. The use of symbols, signal words or hazard statements other than those which have been assigned to each of the GHS hazard classes and categories would be contrary to harmonisation.

  • The Role of Product Composition in Determining Detonation Velocity
    The Role of Product Composition in Determining Detonation Velocity... 459 Central European Journal of Energetic Materials, 2014, 11(4), 459-474 ISSN 2353-1843 The Role of Product Composition in Determining Detonation Velocity and Detonation Pressure Peter POLITZER*, Jane S. MURRAY Department of Chemistry, University of New Orleans, New Orleans, LA 70148, USA *E-mail: [email protected] Abstract: Four sets of rules for predicting the detonation product compositions of explosives have been investigated: the Kamlet-Jacobs, the Kistiakowsky- Wilson, the modified Kistiakowsky-Wilson and the Springall-Roberts. These can result, for a given compound, in significantly differing detonation products and amounts of heat release. However the resulting detonation velocities D and detonation pressures P obtained for the compound using the Kamlet-Jacobs equations are generally quite similar, with the Kamlet-Jacobs rules leading to the D and P that are, on average, closest to the experimental. The fact that the variations among the D and P values are relatively small can be attributed to a balancing of opposing effects relating to the quantities of gaseous products and the heat releases. Accordingly, obtaining reasonable accuracy for D and P does not necessarily imply corresponding accuracy for the product composition and heat release that were used. The analysis presented explains the observations that D and P can be correlated with loading density alone, even though product compositions are known to change with density. Keywords: detonation velocity, detonation pressure, density, detonation product composition, detonation heat release 1 Detonation Performance Two key criteria for evaluating explosives are detonation velocity (D) – the stable velocity of the shock front that characterizes detonation – and detonation pressure (P) – the stable pressure that is developed behind the front [1-6].
