New energetic oxidizers ?

DubaiAmateurRocketry - 18-10-2013 at 01:32

Here are some energetic oxidizers i found.

however I think better ones than be made from guanidine, triazole or tetrazole as starting.

Here are some already existing, recently examined oxidizers.

I wont post any ADN, HAN, or HNF since they are already known.

BTNA
Bis(2,2,2-trinitroethyl) amine
C4H5N7O12




TAF
2,2,2-Trinitromethylazidoformate
C3H2N6O8
This one have lower senstivity than i thought ! This looks promising, it has both energetic groups and oxygen positive.





TNC and TNC-NO2

2,2,2-Trinitroethyl carbamate (TNC)
2,2,2-TRINITROETHYL NITROCARBAMATE (TNC-NO2)

the latter one is also promising with oxygen balance +15




Is it possible to get multi-nitrated, insensitive, oxygen-positive tetrazoles ?
tetrazole not only have higher density, it is also much more energetic.

And what is promising about TNC-NO2?

first detonation performance like Dcj and Pcj are moderate and close to TNT. also, nothing great about the density which is also moderate. The worst thing is decomposition temperature which is low (153°C) and this compound is sensitive to friction, impact and electrostatic discharge. these properties are not desirable for an explosive compound. If the TNC-NO2 is compared to NH4ClO4 we will get the same specific impulse Is. Taking into account that TNC-NO2 and NH4ClO4 have the same performance as propellant and that the later is much easier to synthesize obviously TNC-NO2 will not replace ammonium perchlorate. Maybe the only advantage of TNC-NO2 over NH4ClO4 is that the former has a chlorine-free burning products.

Yes, but they are all in acceptable range, the sensitivity of say, ADN which is also considered ''promising'' has sensitivity of 4J, and even more its melting point is around 90.

Well, yes AP is very good already.

Is it possible to hang some NO2 or ONO2 groups in triazoles and tetrazoles ?
So it can act as oxidizer while having those energetic nitrogen bonds
