标 题 :Method of generating crosslinking sites on the surface of ammonium perchlorate in solid interceptor propellants
发明人：SAYLES DAVID C
权利人:US ARMY
摘要:A method of generating reactive crosslinking sites on the surface of the onium perchlorate particles contained in a Catocene-catalyzed, high-burning rate solid propellant composition by a processing agent which also results in a major improvement in the processibility thereof. The fluid state of the propellant is retained during mixing as a result of interaction between the processing agent prepared prior to incorporating it or when the processing agent is prepared in situ during the propellant mix cycle. There are two alternates available toward improving the processibility of Catocene-catalyzed, high-burning rate propellants. These are: a. The synthesis of a condensation product (processing agent) by the interaction at room temperature of 1,3,5,7,9-pentaazanonane, acrylonitrile, oxiranylmethanol and octadecyl isocyanate in predetermined ratios; or b. Incrementally adding the octadecyl isocyanate to the propellant mix which incorporates the glycidol reaction product of cyanoethyl-substituted tetraethylenepentamine (Tepanol). A major improvement in processing can be effected as a result of the additions of octadecyl isocyanate in 1,2, or 3 increments to the Tepanol-containing mix.

标题 :Preparation of substituted-1,2,3-triazoles

摘要:The invention provides a high yield/isomerically pure synthesis of new 1-amino-3-substituted-1,2,3-triazolium salts and their subsequent transformation into isomerically pure 1-substituted-1,2,3-triazoles. These new 1-amino-3-substituted-1,2,3-triazolium salts are easily isolated and can be stored at ambient conditions with no degradation or isomerization. These quarternary salts are easily converted with appropriate silver salts to a wide array of new quarternary salts with various anions, with many of these new salts having melting points below 100 C, classifying them as ionic liquids. Subsequent diazotization of these 1-amino-3-substituted-1,2,3-triazolium salts results in high yields of isomerically pure 1-substituted-1,2,3-triazoles, that until this invention were problematic to make pure without tedious reagents or workup procedures. Both classes of materials (1-amino-3-substituted-1,2,3-triazolium salts as well as 1-substituted-1,2,3-triazoles) should be of high interest as these classes of materials are known to be very important pharmaceutical materials for a wide array of medical and agricultural applications as well as possible propellant applications.

标题 :Synthesis of 2-nitroimino-5-nitrohexahydro-1,3,5-triazine

摘要:A method of forming 2-nitroimino-5-nitrohexahydro-1,3,5-triazine is presented. The method contains the steps of mixing nitroguanidine, formaldehyde, tert-butyl amine, and water to form an aqueous-based mixture containing an intermediate reaction product; separating the intermediate reaction product from the aqueous-based mixture by filtering out the suspended intermediate reaction product; and mixing the intermediate reaction product within a multi-acid solution containing sulfuric acid and nitric acid. Ammonium chloride is then added, thereby forming 2-nitroimino-5-nitrohexahydro-1,3,5-triazine. A gas generating system 200 containing a gas generant formed in accordance with the present invention is also contemplated.
