标 题 :Metal chalcogenide quantum dots for the detection of nitroaromatic chemicals
发明人：BACA ALFRED J; MEYLEMANS HEATHER A; CAMBREA LEE R; BALDWIN LAWRENCE
权利人:US NAVY; US NAVY
摘要:The synthesis of AgInS 2 based quantum dots and their use as fluorometric probes for the selective detection of nitroaromatic explosive chemicals, without the use of ligands specific to nitroaromatic explosive chemicals. These quantum dots allow the detection of nitroaromatic explosive molecules by eye. The present invention also represents a simple patterning method for quantum dots on substrates, including low cost filter paper. The ease of fabrication, use of less toxic materials, and the selectivity to nitroaromatic explosive chemicals results in a practical solution to the development of a portable fluorescent probe based on quantum dots for the detection of nitroaromatic explosive chemicals.

权利人:UNIV CALIFORNIA; MITCHELL ALEXANDER R; PAGORIA PHILLIP F; SCHMIDT ROBERT D
摘要:The present invention relates to a process to aminate electrophilic aromatic compounds by vicarious nucleophilic substitution of hydrogen using quaternary hydrazinium salts. The use of trimethylhydrazinium iodide, as well as hydroxylamine, alkoxylamines, and 4-amino-1,2,4-triazole to produce aminated aromatic structures, such as 1,3-diamino-2,4,6-trinitrobenzene (DATB), 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) and 3,5-diamino-2,4,6-trinitrotoluene (DATNT), is described. DATB and TATB are useful insensitive high explosives. TATB is also used for the preparation of benzenehexamine, a starting material for the synthesis of novel materials (optical imaging devices, liquid crystals, ferromagnetic compounds).

摘要:Aminonitrobenzodifuroxan (CL-18) is prepared by directly converting pentanitroaniline to aminonitrobenzodifuroxan with heat in the presence of an excess of sodium azide. The pentanitroaniline is prepared in high yield from 3,5-dinitroaniline with a mixture of nitric acid and sulfuric acid in which the final sulfuric acid concentration is from 99.0 to 99.5%.

摘要:The present invention is directed to the synthesis of useful products from the explosive trinitrotoluene. This substance has a limited shelf life as a reliable explosive and large quantities of it have and will become surplus. Ecologically safe, and preferably commercially useful ways of disposing of it are therefore much to be desired. In the present invention the end products are nitroindoles of the general formula 4-Z 1 ,6-Z 2 indole wherein Z 1 and Z 2 are the same or different and are halo or nitro provided at least one of said groups is nitro.

摘要:The present invention relates to a process to aminate electrophilic aromatic compounds by vicarious nucleophilic substitution of hydrogen using quaternary hydrazinium salts. The use of trialkylhydrazinium halide, e.g., trimethylhydrazinium iodide, as well as hydroxylamine, alkoxylamines, and 4-amino-1,2,4-triazole to produce aminated aromatic structures, such as 1,3-diamino-2,4,6-trinitrobenzene (DATB), 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) and 3,5-diamino-2,4,6-trinitrotoluene (DATNT), is described. DATB and TATB are useful insensitive high explosives. TATB is also used for the preparation of benzenehexamine, a starting material for the synthesis of novel materials (optical imaging devices, liquid crystals, ferromagnetic compounds).

摘要:The present invention relates to a process to produce 1,3-diamino-2,4,6-trinitrobenzene (DATB) or 1,3,5-triamino-2,4,6,-trinitrobenzene (TATB) by: n (a) reacting at ambient pressure and a temperature of between about 0° and 50° C. for between about 0.1 and 24 hr, a trinitroaromatic compound of structure V: ##STR1## wherein X, Y, and Z are each independently selected from --H, or --NH 2 , with the proviso that at least 1 or 2 of X, Y, and Z are hydrogen, n with an amount effective to produce DATB or TATB of 1,1,1-trialkylhydrazinium halide wherein alkyl is selected from methyl, ethyl, propyl or butyl and halide is selected from chloride, bromide or iodide. n in the presence of a strong base selected from sodium butoxide, potassium butoxide, potassium propoxide, sodium propoxide, sodium ethoxide, potassium ethoxide, sodium methoxide, potassium methoxide, and combinations thereof; n in a solvent selected from the group consisting of methanol, ethanol, propanol, butanol, dimethylsulphoxide, N-methylpyrrolidone, hexamethylphosphoramide, dimethylformide, dimethylacetamide and mixtures thereof, provided that when alcohols are present primarily DATB and picramide is formed; and (b) isolating the DATB or TATB produced. DATB and TATB are useful specialty explosives. TATB is also used for the preparation of benzenehexamine, a starting material for the synthesis of novel materials (optical imaging devices, liquid crystals, ferromagnetic compounds).
