need a gas making reaction

khanoomkochooloo - 27-8-2005 at 10:42

hi ineed some sort of a reaction which would produce gas with high speed could anyone help?

dont talk about peas and beans and..stuff!:)

How much effort did you put in this question. It is soooo trivial.

One such fairly safe reaction is baking soda (NaHCO3) added to a dilute strong acid. Instant violent production of gas (you should find out which one) without production of significant heat.

If we are going in a more energetic direction, then we can add many more, e.g. detonation of NH4NO3: solid --> all gases (water also is a gas at the temp at which this reaction occurs). Of course there are more powerfull ones, this is just an example. I doubt, however, that the OP is looking for this kind of reactions.

Khanoomkochooloo, I am assuming that you are looking for a cold gas generator, and maybe inert to. Please be more specific about volume, volume per second, temperature, gas properties etc. The link I have given you here, is all about inert gas generators, and has the folowing topics:

See catalogs for "inert gas generator"
Search product announcements for "inert gas generator"
Search by part number
See All Engineering Web Results for inert gas generator
Limit your Web search to:
- Application Notes
- Material Properties
- Patents
- Standards

If however, you are looking for something "hot", then Wouter Visser may help you out.

A collection of pyrotechnic compositions:
http://www.wfvisser.dds.nl/compoDB.html

Hydrogen peroxide, together with a catalyst, produces Oxygen and Steam. Potassium permanganate or Copper powder may be used as a catalyst. If you drop a crystal of Potassium permanganate into Hydrogen peroxide, an emediate violent gasouse reaction takes place.

Caution: This reaction is violent, and hot gasses are produced !
