Decomposition of hydrogen peroxide can be funny


An example which I like - tablet of hydroperite (hydrogen peroxide+urea) can be decomposed by adding very little amount of potassium permanganate. The exothermic decomposition of hydrogen peroxide gives enough heat to boil produced water.

What about decomposing a lot of 30% hydrogen peroxide at once? Say, about a metric ton at once.
Are there such experiments?

The effect would be very similar tothe small scale, not much difference, with considerably more risk

Scaling up reactions, especially exothermic decomposition is not easily predictable. A metric ton. That's a lot of steam and oxygen.

The Germans used to mix 80% hydrogen peroxide (T-stoff) as one part of a bipropellant for their Me-163 rocket-plane. They had a tendency to explode in a spectacular fashion even when hit. Perhaps you can find videos of it online.

Hydroperite is cheap in Russia.
Good thing but not findable in German eBay.

A tonne of peroxide going boom is not an experiment.
These things tend to be called industrial accidents and they are not pretty.

Even 100 tons of TNT are ignited at once!

TNT has but one purpose. We expect it to go boom. And we take measures to control the timing and location.
Peroxide has multiple uses. Explosions are not its primary purpose. It reacts with many other chemicals. If it reacts in a hurry in a large quantity then that is slmost certainly undesirable.
