In-Depth Information
acid, 40 % sodium hydroxide, and sodium hypochloride are designed and compared
with isopropyl nitrate. The results are in Table
6.1
.
There is not any reaction for mixtures of 1,3-diazidopropane and isopropyl
nitrate with any ratio. Experiments indicated that as a liquid explosive, the mixture
of 1,3-diazidopropane and isopropyl nitrate increases both the oxygen consumption
and gas products.
(2) Reactions with reductants
The reactions of 1,3-diazidopropane and strong reductants are also designed.
Triethyl aluminum was chosen as the strong reductant. One reaction is that 1,3-
diazidopropane and triethyl aluminum are mixed in inert gas; the second is in air.
The results are in Table
6.2
.
The data from above table indicate that the liquid explosive with bodying triethyl
aluminum as the main fuel, a catalyst and a sensitizer have both maximum oxygen
consumption and gas products. The chemical stability is also good. The explosive
with 1,3-diazidopropane as the main fuel, triethyl aluminum as catalyst and sen-
sitizer is also a kind of good-performance liquid explosives.
6.2.5.2 Explosive Properties of 1,3-Diazidopropane

Combustion/burning experiment of 1,3-diazidopropane
200 g 1,3-diazidopropane is placed in a 500-mL thick wall glass container. A
pipe of 6 mm double-base propellant is plugged in the center. Ignite the double-base
propellant from the top, and 1,3-diazidopropane starts burning, until the glass
container explodes.
