According to Wikipedia - http://en.wikipedia.org/wiki/Toluene

Toluene can be used as an octane booster in gasoline fuels used in internal combustion engines. Toluene at 86% by volume fueled all the turbo Formula 1 teams in the 1980s, first pioneered by the Honda team. The remaining 14% was a "filler" of n-heptane, to reduce the octane to meet Formula 1 fuel restrictions.
Erm, correct me if i'm wrong here, and i'm sure BruceV8 would know more than me, but isn't toluene a major ingredient of TNT??

From the same article


but if heated it can give dinitrotoluene and ultimately the explosive trinitrotoluene (TNT).

You think that that stuff is bad you should look at some of the stuff they used to full the pre war cars with.

Years ago (like pre H&S and Unleaded days) Merc brought a couple of theirs over and spilt a little of the jungle juice on the floor of the garage at Silverstone. It melted the concrete yikes

it tastes bad too but certainly hits the spot!

Hmmm, can concrete melt by chemical reaction??

there is no toluene in (pure) TNT...

however TNT is made from toluene.

toluene in itself is not explosive.

TNT is a toluene molecule where three hydrogen atoms have been swapped for NO2 (one nitrogen and two oxygen) groups.

You will find most explosive contain a lot of nitrogen atoms - this is because the formation of nitrogen gas - N2, is very favourable. The two nitrogens in nitrogen gas (dinitrogen) have a very strong bond to eachother.). The formation of this bond releases a lot of energy... hence the explosive characteristics of such materials.

let's think about this.

concrete is typically less reactive than most metals.

the fuel tank needs to be made of something.

plastic was not invented, certainly not chemically resistant stuff like PTFE.

what did they build the fuel tank for the concrete dissolving fuel from?

Well i wasn't suggesting that it was purely toluene in TNT, but that's fascinating, i learnt something new today, thanks mate smile

I know they had to completely drain the fuel system every time the car was used to prevent the fuel from corroding the tanks and fittings.

We have to do that with our dragster that runs on methanol...

Eats aeroquip for fun and the bores if you don't run lube in the fuel.

No idea!

All I know is car wheeled in from transporter into garage - No hole.

Mechanics start to fill car up and suddenly lost of shouts of "Got in Hemel" and other Germanic words of concern, vapour starts to fill garage and everyone cleared away for garage and vicinity.

An hour later and there is a hole in the floor of the garage about the size of a side plate and about 2-3cm deep.

Perhaps 2+2+7, I'm no chemist, but that was what I was told had happened at the time by an adult who witnessed it (i was there but was only a nipper).

Benzine-ring chemistry. I think benzine was proved to be fairly carcinogenic in its various forms.

benzene is carcinogenic but i use it fairly commonly as a solvent. It used to be used for washing glassware and even hands!! in chemistry labs. I think it is a mild ish carcinogen that was widespread... It's not like walking around with a lump of radium in your pocket or anything.

wonder if they used hydrazine or some derivative. hydrazine is H2N-NH2 so it has those all important nitrogens again.

it if hydrazine i can believe what it did to the concrete - apologies rude boy smile

sounds a bit dodgy though.

edit: a quick google found this:

Drain it into what, and why didn't they use the same material as the receptical to make / line the fuel tank.
