Abstract: 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%.

Abstract: This invention illustrates a new compound, octanitrobenzidine. It is utild as a new high energy explosive compound. Octanitrobenzidine is formed by dissolving a tetrqanitrobenzidine with sulfuric acid in the presence of a metal sulfate catalyst. This reaction mixture is further reacted with nitric and sulfuric acid at a temperature sufficient to complete the reaction, then rapidly cooled, and octanitrobenzidine is recovered.

Abstract: A method of preparing 4,6-dinitro-5,7-diaminobenzofuroxan from 4,6-dichloenzofuroxan.

Abstract: A new one-step synthesis of cyclic 1,3 dinitramines is disclosed. This syesis utilizes a solution of N.sub.2 O.sub.5 in 100% nitric acid as the nitrolyzing media. The polynitramines thus produced find utility as explosive and propellant ingredients, gas generants and in other ordnance applications.

Abstract: Pentanitrotoluene is prepared by a method which comprises preparing an amdinitrotoluene from a precursor of either TNT or 2,5-dinitro-3-methylbenzoic acid, nitrating the aminodinitrotoluene to produce a nitramine intermediate, converting the nitramine intermediate to an aminotetranitrotoluene and oxidizing the aminotetranitrotoluene with peroxydisulfuric acid to pentanitrotoluene. Pentanitrotoluene is an explosive.

Abstract: A one pot process for the preparation of trinitrophloroglucinol by the addition of a nitric acid and sulfuric acid mixture to phloroglucinol in sulfuric acid where the nitric acid and phloroglucinol are present in stoichiometric amounts.

Abstract: Aminopolynitrotoluenes, having energetic properties, including 4-amino-2,,6-tetranitrotoluene 3-amino-2,4,5,6-tetranitrotoluene and 2-amino-3,4,5,6-tetranitrotoluene, and methods for their preparation. Also, 4-amino-N,2,3,6-tetranitrotoluene and 4-amino-N-2,3,5,6-pentanitrotoluene, each having energetic properties. Further, a process for preparing 2,3,4,5,6-pentanitrotoluene.

Abstract: A laser dye, 2-keto-4,6,8,8-tetramethyl-8,9-dihydro-2H-pyrano(3,2-g) quinoline, is prepared by mixing m-aminophenol and ethyl acetoacetate and heating the mixture.

Abstract: Hexanitrobenzene is prepared by oxidizing the amine group of pentanitroaniline with H.sub.2 O.sub.2 in H.sub.2 SO.sub.4. The compound is a high density explosive.

Abstract: Trinitrotoluene is selectively reduced by reaction with H.sub.2 S in p-dine to produce 4-amino-2,6-dinitrotoluene. This latter compound is then nitrated with HNO.sub.3 in H.sub.2 SO.sub.4 to produce pentanitroaniline which is, in turn, reacted with NH.sub.3 in benzene, methylene chloride or another suitable solvent to produce triaminotrinitrobenzene (TATB). TATB is useful as an explosive.
