Description
| - Práce je věnována 2,4,6,4,6,2,4,6-octanitro[1,1,3,1]-terfenylu (ONT), 2,2,2,4,4,4,6,6,6-nonanitro[1,1,3,1]-terfenylu (NONA), 2,4,6-tris(2,4,6-trinitrofenyl)-1,3,5-triazinu (TPT), N,N-bis(2,4-dinitrofenyl)-2,4,6-trinitroanilinu (NTFA), 2,2,4,4,6,6-hexanitrobifenylu (HNB), 1,3-dinitrobenzenu (1,3-DNB) and 1,3,5-trinitrobenzenu (TNB). Iniciační reaktivita těchto polynitroarenů byla studována s použitím dat neizotermické diferenční termické analýzy (DTA), jejich teplot vzbuchu, citlivostí k nárazu, údajů z ruské manometrické metody a detonačních charakteristik. Pro porovnání byla také použita publikovaná data 2,2,2,2,4,4,4,4,6,6,6,6-dodecanitro-[1,3,1,1]quaterfenylu (DODECA). Práce specifikuje a diskutuje vztahy mezi výsledky použitých metod, včetně tvarů modifikovaného Evans-Polanyi-Semenov vztahu. Studované substance lze seřadit podle rostoucí tepelné reaktivity v řadu ONT-TPT-NONA-NTFA. (cs)

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.
