Concentrated H2O2?


Recommended Posts

There's no simple, non-industrial way to make concentrated hydrogen peroxide in your home. Concentrated hydrogen peroxide is very dangerous, and that's the reason why it is only available for purchase in the lab.

 

If you're lucky, you may be able to find a 30% solution available somewhere on the internet, but I would use caution.

a leftover knowledge relic of my pyro days (never personally tested) is that if you put low-conc H2O2 in the freezer, you'll get a layer of ice floating on top of a now-slightly-higher concentration of H2O2. you can then repeat this, measuring the water you take out as ice in order to get a value for the remaining solution's concentration.

 

however, wikipedia tells me that there's only 0.43 degrees difference between water and peroxide's melting points. however, it says there's a 50 degree difference in their boiling points. it seems to me that if you kept the low-conc solution on a rolling boil at around 105 degrees, plenty of water should boil off, but not too much H2O2. however, capturing the water for stoichiometry would be harder this way.

Google 'rocket grade hydrogen peroxide' or 'propulsion grade hydrogen peroxide'. It's available in +98% concentrations. It usually comes in 30 gallon drums but you might be able to obtain a 'sample' quantity if you contact some of the manufacturers and ask. Beware, the hazmat fee on transporting it is high so there will be some high shipping fees for even a small quantity.

1) Concentrated hydrogen peroxide rapidly diffuses through intact skin until it hits living tissue. Living tissue has catalase. The hydrogen peroxide then microdetonates into subcutaneous bubbles of oxygen. The pain is awesome.

 

2) Concentrated hydrogen peroxide can be detonated by traces of transition metals such as iron or copper.

 

3) Hair bleach uses ca. 30% hydrogen peroxide. It is on the Homeland Severity watch list re ketone peroxide explosives.
