I've seen some diethyl zinc used for rocket and missile fuel.
Could anyone tell me more about that.

Sorry. Tried but I couldn't find anything about it except in a medical context. http://astronautix.com/props/index.html doesn't even have it.

Anyway, welcome to the boards! We're glad to have you.

Info I found rocket related:


Quote:
No, kerosene is a classic nonpolar solvent and permanganate is a salt.
You might be able to pursuade an alcohol mixture with a few % water to
dissolve enough permanganate to be hypergolic with peroxide, but I'd
guess that the solubility would be poor and the salt would be in danger
of crystallizing out.

For kerosene, it might be possible to add a touch of diethyl zinc to
make it hypergolic with peroxide yet not make it pyrophoric with moist
air. Having worked with DEZ in the distant past, that's not a game I'd
like to play myself.

I'm happy with a good simple augmented spark igniter since it works with
anything we've picked from column A and column B. (And with six you get
eggroll.)

Oxidizers Fuels
LOX Alcohol
GOX Propane
N2O Ethane

We haven't tried it with kerosene, but that's just personal prejudice-
I'm confident that it too would light off nicely.

Came across a very nice intresting page: http://www.bnl.gov/esh/shsd/cms/Safety_ ... bility.htm (to learn something new), but this is off topic

From what I see... some people talk about it... but not much is found in google about it, so I guess no-one or almost no-one really uses it for rockets and missile fuel etc.

Props to Sigurd for the research, I couldn't find anything. Welcome to the forums Katja.

From those texts, it appears that DEZ is some pretty nasty stuff, pyrophoric with moist air.
