1,3,3-Trinitroazetidine (TNAZ) has been prepared at a laboratory scale in HEMRL. The structure of the compound has been confirmed by IR, NMR, mass, elemental analysis and by X-ray crystallography. HPLC technique has been employed to confirm the purity of TNAZ (>99%). The compound is further characterized by thermal techniques and is found to undergo limited decomposition at its melting point. Small scale sensitivity tests have also been carried out and the results show that TNAZ is significantly more sensitive to mechanical stimuli than TNT. [Copyright &y& Elsevier]

Potassium, rubidium, and cesium salts of 5,7-diamino- 4,6-dinitrobenzofuroxan (CL-14) have been prepared by reacting sodium salt of 5,7-diamino-4,6-dinitrobenzofuroxan with alkali metal nitrate in an aqueous medium. The structure of the compounds was unequivocally confirmed by spectra data, elemental analyses, and estimation of metal content. Further, the compounds have been evaluated for explosive and thermal properties and found more suitable as compared to alkali metal salts of 4,6-dinitrobenzofuroxan (DNBF). [ABSTRACT FROM AUTHOR]

2-Oxo-1,3,5-trinitro-1,3,5-triazacyclohexane (Keto-RDX or K-6), the most powerful energetic material among nitrourea explosives, has been prepared and scaled up at laboratory level. The identity and purity of the product are tested by elemental analysis, IR, NMR, mass and HPLC techniques. Thermal response and sensitivity experiments on K-6 are also described. The data on sensitivity shows that K-6 can be utilised practically only in phlegmatized form. [Copyright &y& Elsevier]
