This book was released on 1990 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is a summary of observations and possible chemical mechanisms for catalysis of the decomposition and combustion of the nitramines HMX and RDX, and of propellants derived from them, by salts containing these anions is reviewed, as is available information on the effects of these salts on decomposition and combustion of HMX and RDX. The emphasis is on thermal decomposition and on salts with alkali metal anions. The pure salts appear stable under vacuum or inert gas to about 700-800 C, but there is a report of H2 evolution lower temperatures (ca 300-600 C, depending on the nature of the salt) is observed. When the salts are heated together with RDX, considerable enhancement of the decomposition rate of RDX is observed; this begins at the melting temperature of pure RDX and becomes intense, leading to a lower, mush sharper decomposition exotherm. These observations seem consistent with a catalysis mechanism involving attack of the B-H hydrogens of the catalyst on the nitramine, but it is difficult to evaluate the role of other processes, and of reaction of the catalyst with products.

Download or read book Borohydride Catalysis of Nitramine Thermal Decomposition and Combustion 2 Thermal Decomposition of Catalyzed and Uncatalyzed HMX Propellant Formulations written by Michael A. Schroeder and published by . This book was released on 1990 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes GC-MS studies on thermal decomposition of HMX, RDX and propellants, with and without catalysis by K2B12H12 or K2B10H10. This work differs from previous work in that it emphasizes the less-volatile decomposition products. Pyrolysis-GC-MS on HMX-GAP and HMX-PEG compositions with and without K2B10H10 has been carried out. Identification of products is in progress; identification of a number of products is discussed. To date, the most mechanically important product identified is probably 1,3,5-triazine. This is believed to be formed from HMX via 1,3,57-tetraazacycloocta-tetraene; this is consistent with the known thermal decomposition behavior of cyclooctatetraene and its azaderivatives. 1,3,5-triazine formation by trimerization of HCN is believed to be relatively unimportant. There is also an unknown component whose highest mass peak is at m/e 70. In addition, further analysis of results from earlier runs on RDX and RDX-K2B12H12 mixtures has been carried out. Based on all of the above, it appears that formation of the m/e 70 unknown decreases with increasing temperature. (aw).

Their high gravimetric heat of combustion enhances the performance of modern energetic materials. Borohydride compounds have proved to be excellent candidates in this application. High-energy Combustion Agents of Borohydrides covers the most recent developments in the advanced combustion agents of borohydrides. Experimental studies covering the synthesis and characterisation of borohydrides are examined, as well as the interactions between borohydride and propellant ingredients. The properties of BHN/nano Al composites are discussed, as is the effect of borohydrides on the properties of fuel-rich solid propellants. The book concludes with a summary of the prospective development of high-energy combustion agents in solid propellants and explosives, and looks into the future development of military applications. Authored by renowned experts in the field, this book will appeal to researchers in academia and industry seeking a better understanding of how to improve the ignition and combustion performance of propellants and explosives.

Download or read book Ignition written by John Drury Clark and published by Rutgers University Press. This book was released on 2018-05-23 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This newly reissued debut book in the Rutgers University Press Classics Imprint is the story of the search for a rocket propellant which could be trusted to take man into space. This search was a hazardous enterprise carried out by rival labs who worked against the known laws of nature, with no guarantee of success or safety. Acclaimed scientist and sci-fi author John Drury Clark writes with irreverent and eyewitness immediacy about the development of the explosive fuels strong enough to negate the relentless restraints of gravity. The resulting volume is as much a memoir as a work of history, sharing a behind-the-scenes view of an enterprise which eventually took men to the moon, missiles to the planets, and satellites to outer space. A classic work in the history of science, and described as “a good book on rocket stuff…that’s a really fun one” by SpaceX founder Elon Musk, readers will want to get their hands on this influential classic, available for the first time in decades.

Download or read book Bretherick s Handbook of Reactive Chemical Hazards written by L. Bretherick and published by Elsevier. This book was released on 2016-10-27 with total page 2058 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bretherick's Handbook of Reactive Chemical Hazards, Fourth Edition, has been prepared and revised to give access to a wide and up-to-date selection of documented information to research students, practicing chemists, safety officers, and others concerned with the safe handling and use of reactive chemicals. This will allow ready assessment of the likely potential for reaction hazards which may be associated with an existing or proposed chemical compound or reaction system. A secondary, longer-term purpose is to present the information in a way which will, as far as possible, bring out the causes of, and interrelationships between, apparently disconnected facts and incidents. This handbook includes all information which had become available to the author by April 1989 on the reactivity hazards of individual elements or compounds, either alone or in combination. It begins with an introductory chapter that provides an overview of the complex subject of reactive chemical hazards, drawing attention to the underlying principles and to some practical aspects of minimizing such hazards. This is followed by two sections: Section 1 provides detailed information on the hazardous properties of individual chemicals, either alone or in combination with other compounds; the entries in Section 2 are of two distinct types. The first type of entry gives general information on the hazardous behavior of some recognizably discrete classes or groups of the 4,600 or so individual compounds for which details are given in Section 1. The second type of entry concerns reactive hazard topics, techniques, or incidents which have a common theme or pattern of behavior involving compounds of several different groups, so that no common structural feature exists for the compounds involved.
