TETRANITROMETHANE
« on: April 17, 2009, 07:34:03 PM »
http://www.roguesci.org/chemlab/energetics/tetranitromethane.html is a synth for it.

Here is some info on it. I am concentrating on it NOT as a HE but for synthises.

This is on TetraNitroMethane from Urbanski.

TETRANITROMETHANE
Tetranitromethane was first obtained by Shishkov [48] in 1857, but it was only
during the World War II that the Germans experimented with it on a large scale,
using mixtures of tetranitromethane with various combustible materials as rocket
propellants.
PHYSICAL PROPERTIES
Tetranitromethane, C(NO2)4, is a heavy oily liquid (sp. gr. 1.65), which solidifies
at +3°C and boils at 126°C without decomposition. It is insoluble in water,
but it dissolves easily in alcohol and benzene. It is a volatile substance with a characteristic
smell, reminiscent of nitrogen oxides.
Menzies [53], later Nicholson [54] and Edwards [551 measured the vapour pressures
of tetranitromethane and obtained similar values.

Nicholson found the following vapour pressures for temperatures ranging from
0°C to 40°C:
Temperature, °C 0 13.8 20 30 40
Vapour pressure, mm Hg 1.9 5.7 8.4 14.9 25.8
Changes in the vapour pressure of tetranitromethane depending on temperature
may be expressed by a first degree equation:
log p = 8.63-2260/T
From the above data Nicholson has calculated the latent heat of evaporation
10.3 kcal/mole. Edwards has given the following figures for temperatures ranging
from 40°C to 100°C
Temperature, °C 40 50 60 70 80 90 100
Vapour pressure, mm Hg 26.5 43.3 68.0 108.0 164.0 239.0 339.6
He has presented changes in vapour pressures as a variable dependent on temperature,
according to the equation:
log p = 7.23-2130/T
and has calculated the latent heat of evaporation to be 9.7 kcal/mole.
CHEMICAL PROPERTIES
Although tetranitromethane does not contain active hydrogen it readily enters
certain reactions. With water it reacts slowly to form trinitromethane, i.e. nitroform:
C(NO2 )4 + HOH -> CH(NO2 )3 + HNO3 (20)
With potassium hydroxide, tetranitromethane readily yields its potassium salt
of nitroform :
C(NO2)4 + 2KOH + CK(NO2)3 + KNO3 + H2O (21)
It react with sodium sulphite to yield sodium trinitromethanesulphonate
C(NO2)4 + NO2SO3 -> (O2N)3CSO3Na + NaNO2 (22)
With copper or nickel in the presence of ammonia it forms complex salts having
initiating properties (Vol. III).
Tetranitromethane is added to compounds having double bonds to form brown
or yellow products. The reaction is very sensitive and may be utilized, for example,
for detecting traces of olefins in paraffin fractions (Werner [56]).
Tetranitromethane reacts with tertiary amines, causing their degradation with
the formation of N-nitroso derivatives of secondary amines. In this way tertiary
amines may be converted to secondary ones (E. Schmidt and co-workers [57, 58]):

EXPLOSIVE PROPERTIES
According to Roth [62], pure tetranitromethane cannot be detonated even when
using 10 g of tetryl as detonator. However, the ability of tetranitromethane to
detonate increases considerably when it contains organic impurities, even in small
quantities.

TOXICITY
Tetranitromethane is highly toxic. Kiese [48] found that 25 mg/per kg of body
weight of tetranitromethane slowly injected intravenously caused transitory
methaemoglobinaemia, as well as lung oedema and damage to the liver, kidney and
central nervous system. Tetranitromethane injected quickly caused necrosis
around the puncture which could be fatal.

Now more...
Formed by passing acetylene gas through 100% (or near to it) HNO3, which forms the intermediate trinitromethane (TNMe), which is then nitrated with more concentrated nitric acid to form the TeNMe. (Ref. IEC 41, pg 2185 y.1949 and J. Chem. Soc, pg 283, y.1920)

^^This needs a Hg (ii) nitrate catalyst.

Have you ever had any experience with it?

From what I have read about this substance it would seem that most clandestine chemist that have had experiance with this substance wouldnt be here to tell up about it ;). Hell even in TSII Strike mentions and explosion that (from the sounds of it) he experianced. I know he had to have access to top notch reagents and chemicals because of his line of work and yet he was still unable to tame this beast and reported blowing the windows out. Im all for danger and excitment but from the literature it seems like this beast is TNT on crack.

The name makes me think that it would be incredibly dangerous, but when you read things from untrust worthy sites such as wikipedia it makes me question.

for instance, on its wikipedia I have found..
 
Quote
It has been investigated for use as an oxidizer in bipropellant rockets, however its high freezing temperature makes it unsuitable. The explosive sensitivity is low, but would be raised by anti-freezing additives. This makes it effectively unusable.[3] In the laboratory it is used a reagent for the detection of double bonds in organic compounds and as a nitrating reagent. It has also found use as an additive to fuel to increase the cetane number.

It claims it has been considered to be put into a rocket, that it has low sensitivity, and that it also IS used in the laboratory for multiple reasons. It seems like if it were dissolved in something that still allowed for it to nitrate, but greatly reduced its sensitivity, it may be worth working with.

TNM is an explosive that is sensitive to heat, friction and shock. It is reasonably expected to be a human carcinogen.
what explosive isn't?  ::)

I think it may be worth it to give research this substance a bit more.

I think the main problem with this chemical isnt the substance itself but the synthesis of it has a tendancy to run away leading to a violent explosion. Alot of what I have read also states that it may be a relativly mellow substance so to speak but the synthesis of it is a read hazard to ones health.

Engager over at science madness posted a photo preperation from acetic anhydride and nitric acid.

ekkk.. As if this substance wasnt a bad enough hazard they reported over at SM the tetranitromethane is 25 times more potant the HCN.

there seems to be a ton of contradicting information in that thread. I don't know what to think of it, other then its probably useless. What is the reaction that happens with it to make nitropropanes?

Page 67 (from the browsers perspective 132 in the book) method #3 it begins with Do not try this method !! Strike repeats Do not try this method...... youll see it ;D

Lizard tech, I didnt even think about that because Iv had it installed for a while.

Never bothered making it, may in the future. I had 1ml from a mate and mixed in 0.3ml tolune and set it off immediately. It appears to be not too nice stuff. Its a nice HE.
