Double Salts of Lead Styphnate

Lead styphnate also forms double salts. Mainly salts with tetrazole compounds were examined as brisant primary explosives. The main attention was aimed at double salts of styphnic acid with l,3-di(5-tetrazoyl)triazene (LDDS) and styphnic acid with 5-nitraminotetrazole (PbNATNR). The study of these salts was done in the 1960s and 1970s. [Pg.148]

The double salt of styphnic acid and 5-nitraminotetrazole (PbNATNR) forms lemon yellow crystals with crystal density 3.6 g cm (density of LS is 3.03 g cm ). It is practically insoluble in cold water, slightly soluble in hot water (0.032 g/100 ml at 25 °C and 0.175 g/100 ml at 70 °Q. PbNATNR is stable under hot water for a long time, no decomposition being observed after several months stored at 65 °C. Thermal stability is superior to that of LS, and weight loss after 24 h at 210 °C is 0.5 % (compared with 24.3 % for LS) [72]. [Pg.148]

The impact sensitivity of LDDS is higher than LS, sensitivity to friction is reported to be of the same order as that of service LA or higher (see Table 5.8) [74]. [Pg.148]

The impact sensitivity of the double salt of styphnic acid and 5-nitramino-tetrazole (PbNATNR) is higher than LS, and it explodes with far greater force and vigor. Brisance of PbNATNR is high, it is superior to that of LS, LA, and MR The ignition temperature is 340 °C (compared with 320 °C for LS) [72]. [Pg.148]

Double salts are prepared by action of aqueous soluble lead salt on an equimolar mixture of styphnic acid (in the form of the magnesium salt) and soluble salt of the tetrazole compound [72, 73]. [Pg.149]

Two structures of basic lead styphnate are commonly used. The first structure represents a double salt of lead styphnate and lead hydroxide (formula I) [20, 33, 39, 64], In the second structure each lead atom is bonded with one oxygen atom of the trinitroresorcinol molecule (formula II) [8, 65, 66],...
