Studies on energetic compounds. 25. An overview of preparation, thermolysis and applications of the salts of 5-nitro-2,4-dihydro-3H-1,2,4-triazol-3-one (NTO).

The research work reported on the preparation, characterisation and applications of more than 50 salts of NTO has been reviewed thoroughly. A broad classification and sub classification of all these compounds has been given on the basis of nature of the compounds with which NTO forms salts. Attempt has been made to discuss the structure of these salts by summarising analytical data reported from 13C NMR. The structure as determined by IR spectroscopy as well as XRD has also been discussed briefly. A generalised mechanism for the thermolysis of the metal salts has also been given and any deviation from this has been narrated in particular cases. The kinetic details, thermodynamical and thermochemical data as well as performance parameters have also been reviewed. Thus, the futuristic potentials of these salts are analysed critically and further studies have been suggested.
