The paper is focused on 2,4,6,4′,6′,2″,4″,6″-octanitro[1,1′,3′,1″]-terphenyl(ONT),2,2′,2″,4,4′,4″,6,6′,6″-nonanitro[1,1′,3′,1″]-terphenyl(NONA),2,4,6-tris(2,4,6-trinitrophenyl)-1,3,5-triazine(TPT),N,N-bis(2,4-dinitrophenyl)-2,4,6-trinitroaniline(NTFA),2,2′,4,4′,6,6′-hexanitrobiphenyl(HNB),1,3-dinitrobenzene(1,3-DNB) and 1,3,5-trinitrobenzene(TNB).The initiation reactivity of these substances has been studied by means of the data obtained from non-isothermal differential thermal analysis(DTA),their ignition temperatures,impact sensitivity,the data obtained from the Russian manometric method and the detonation characteristics.For comparison,also the data published about 2,2′,2″,2,4,4′,4″,4,6,6′,6″,6-dodecanitro-[1,3′,1′,1″]quaterphenyl(DODECA) have been included.The paper specifies and discusses the relationships between the results of various methods used,inclusive of the forms of modified Evans-Polanyi-Semenov relationship.It has been stated that the technologically most attractive substances,out of those studied,can be ordered in the sequence ONT-TPT-NONA-NTFA according to their increasing thermal reactivity.
The paper is focused on 2,4,6,4 ’, 6’, 2 “, 4”, 6 “-octanitro [1,1 ’, 3’1”] terphenyl (ONT) 2, 4,4 ’, 4 “, 6,6’, 6” -nonanitro [1,1 ’, 3’, 1 “] terphenyl (NONA) Trinitrophenyl) -1,3,5-triazine (TPT), N, N-bis (2,4- dinitrophenyl) -2,4,6-trinitroaniline (NTFA) 6,6’-hexanitrobiphenyl (HNB), 1,3-dinitrobenzene (1,3-DNB) and 1,3,5-trinitrobenzene (TNB). The initiation reactivity of these substances has been studied by means of the data obtained from non-isothermal differential thermal analysis (DTA), their ignition temperatures, impact sensitivity, the data obtained from the Russian manometric method and the detonation characteristics. For comparison, also the data published about 2,2 ’, 2 ”, 2, 4 Quaterphenyl (DODECA) have been included. The paper has described the relationship of the quaternary between the results of various methods used, inclusive of the forms of modified Evans-Polanyi-Semenov relations hip. It has been said that the technologically most attractive substances, out of those studied, can be ordered in the sequence ONT-TPT-NONA-NTFA according to their increasing thermal reactivity.
