Distill Hydrogen Peroxide

Picture of Distill Hydrogen Peroxide
If you have read some of my other Instructables you know that a lot of them require oxygen either from the surrounding air or from an oxidizer. Potassium Nitrate is the most common and easily obtainable but, for those of you who, for whatever reason can't obtain it can make your own from hydrogen peroxide.

Step 1: Gethering Materials

Picture of Gethering Materials
For materials you will need four things:

1. Hydrogen Peroxide (The Kind Diluted In Water)
2. A small glass or plastic cup.
3. Soluble salt (I used Morton's)
4. A small amount of your time.

Step 2: Distillation

Picture of Distillation
The First and only step is to pour about one teaspoon of salt into you cup. Next pour three teaspoons of Hydrogen Peroxide on top of it. This mixture can be enlarged but remember to keep the solution at a ratio of 1:4. 1 being the salt and 4 being the Hydrogen Peroxide. After you have added all ingredients stir them together inside the cup. After all or most of the salt is dissolved let your solution sit until you see two layers in the liquid. These will be the salt water and the Hydrogen Peroxide separating. I am pretty sure the top one will be the Hydrogen Peroxide and the bottom one will be the salt water. Comment at the bottom to tell me what you find. I would also like to know what use you have found for it.

Have fun and enjoy!

This topic is an insult to chemists everywhere. Give me physical evidence that hydrogen peroxide *can* be salted out, and I'll give you a full apology. Until then, my mixture of saltwater and hydrogen peroxide remains a fully miscible mixture of saltwater and hydrogen peroxide.

Meanwhile, back to freeze distilling, like a regular person.

I'm not the guy your asking, but I will give it a try, If it burns well in my gas engine, I will let you know. (answering because you posted you comment over a year ago) According to a documentary on Hydrogen peroxide, it should burn in a gasoline engine, (high consentrate hydrogen peroxide)

You are absolutely right about this. Also, plastic cup? At high concentrations of H2O2 a lot of things catch fire on contact, so even if this process worked (it doesn't), there are huge safety issues not discussed at all.

That said, I agree; total hoax. You need to use an actual distillation process.

What is the consentration (%)?

I'm at a loss with chem but theoretically you could use electrolisys to pull this off right ?
liquid Hydrogen Peroxide makes a wonderful rocket fuel. no need for an oxidizer tank for the Hydrogen Peroxide contains both the oxidizer and the fuel (hydrogen as the fuel, oxygen as the oxidizer)
When H2O2 is used as a MONOPROPELLANT, there is no fuel nor oxidizer. The compound is broken down by catalytic action of a silver screen, evolving O2 and H2O and generating heat. The Bell rocket belt uses this method for relatively safe rocket thrust close to the body of the operator. The exhaust temperature and composition are safer than most other reactions would produce. The downside is a lack of specific impulse, because the reaction is relatively tame.
I'd like to know if this fellow is still alive.
jpoopdog is confusing "I got away with it" with "it must be safe, because I got away with it".

Just for completeness, lead poisoning is generally an accumulate heavy metal poison. As such, it rarely kills immediately, unless of course the lead is provided as a soluble salt. The symptoms of lead poisoning are often found in cognitive dysfunction (children who ate lead based paint don't do so well in school).

I'm all for supporting inquisitive thought but draw the line when it puts the individual at serious risk of harm (including death). What fascinates me is that in today's climate of terror threats, much of what jpoopdog has admitted to would be considered a felony.

BTW, I'm saying this from the perspective of someone who has been both a chemist (doctoral program in physical chemistry many, many years ago) and a medical doctor. Many of the things I "got away with" as a high school student were never safe. I just "got away with it". No one was seriously hurt (although a friend has a keloid scar on his knee from a conc nitric acid bottle that he grabbed by the glass stopper and poured on himself. Bad luck - but it was MY bottle of conc acid.

Do you self a favor before it is too late. Stay away from energetic compounds (explosives and propellants) until you have formally studied them. Chemistry is a great field to study - I know - I did it for many years but you don't want to hurt yourself or others.

Much of what you have said in these posts will hurt someone. Waynesl gave you some good advice. If you're still alive (and not in jail), head it.

Good luck,
nitrous
So, how do you make a rocket then?

wrong. The reaction of decomposing H2O2 is 2 H2O2 > 2 H2O + O2 + heat. This is not a Redox Reaction. However the O2 can then be used as a oxidizer. For instance a common liquid fuel rocket engine is to pass high concentrated H2O2 over a silver screen (catalyst to decompose the H2O2) into the combustion chamber and add kerosene to it. The heat of the decomposition is enough to cause the kerosene to burn with the O2 created. However the decomposition of the H2O2 would produce a thrust on its own given that it is going from a liquid to a gas and being heat to produce a pressure.
Hydrogen Peroxide works as a stand alone fuel. Old torpedoes used h2o2 solely as a fuel (with a copper pellet as a catalyst to separate it into it's component gasses), complications of which caused the sinking of several subs. They're even still in use on modern satellites to control their orientation, because it's easy to precisely control the thrust.
yes that is true. I already said it would work by itself. see last sentence from above. I was merely pointing out that it is not a Redox Reaction as rocketguitarguy had stated but was instead a decomposition.

so can i use this to make black powder?
use very pure h202 instead if kno3. use too much and it will oxidize on contact with the charcoal and sulfure, not enough and you end up with a wet black mess. it can be ignited by catalycticaly decomposing the "wet powder" , in an exothermic, but fast reaction, its only realu use though would be for a very quick production rocket fuel, nothing else, its why people dotn use it, its too hazardous, plus not many people would do it anyway as pure h2o2 is hard to come by
First of all, recipe for disaster. Second, where you gonna get very pure h2o2? Third, it won't even work.
trolling dude, trolling. i was like 14 at the time
Lol, take care with your trolling. Some idiot will take it seriously, and try it.
anyone listening to this should know it would never work unless the carbon and sulfur used was atomized and at leat 99.995% (LR grade) pure. otherwise it would oxidize on contact. anyways it wouldnt work. rockets i have checked use parrafin and some agent to help decompose water as the H²O² decomposes .
Be severely careful. The reason why H2O2 is normally in a 3% volume is because it is highly reactive. in chemistry labs we only use a max of 10%. everything above 30% is highly touch reactive and very dangerous
In general, chemistry labs use 30%.

None of this answer the question of which is water and h2o2 and I wana know too so Plc answer

Please never try to talk about chemistry ever again. I don't believe you said a single correct statement in your entire post.
its probable, that means possible. ive done the simulations and it seems to work. as what i said was true about mixing a peroxide with a gaseous acid to make hydrogen peroxide, and it is made very pure, so long as you use sulphuric acid not hydrochloric, i just realised that hydrochloric acid reacts with h2o2 to make aqueous chlorine, but its not likely that youll get large amounts of the stuff.
never make such rash acusations without thinking something through
This is me being nice, jpoopdog. As you found on Jan. 2nd, your ideas about chemistry are very mixed up. If you persist in this poorly-conceived activity, you'll probably wind up in hospital. Your theories are spun out of ignorance and hubris, making you a very dangerous person. I'm being as nice as I can when I suggest you stop posting nonsense which may inspire some gullible reader to do something dangerous. Instead, you should go to school and learn from a professional chemist, after which you'll be able to make propellants that propel instead of detonating.
I am now better educated with the safer practices of chemistry.
But ill tell you why i was not discouraged by your warnings.

every time i was told not to do something because there was a 99% chance it would explode in my face and hospitalize me, and not do what i wanted it to, it worked fine, i keep my face. from experience, i learnt that when someones says its very dangerous and will definitely maim you, it actually meant, where gloves and glasses, and youll be fine.

I smelted lead, im not dead from lead poisoning. i had an allergic reaction to the lead oxides left behind after smelting, only to find i have a lead and silver allergy.
I opened a bag of aluminium powder, and it didnt burst into flames like everyone warned. I made HMTD and intentionally mishandled it just to see what its limits were, i smashed a small vial on the ground, and it didnt explode, i was told a slight bump would make it go off.
I asked around here if it was possible to distill ammonium hydroxide, without getting any soap form the soapy ammonia into the clean product. i wanted a simple yes/no answer, but people raved on about how its so dangerous and too risky that ill ruin my lungs somehow and it will explode and somesuch, and not to do it. i did it, and found out i was right, the soap didnt vapourize.


Anyway, now i cant find that post about the exploding mix, but ill have you know i did not post that, plus it would never happen unless its heat was raised spontaneously, and or pressurized.
I dont know how, maybe someone hacked my account, or a moderator just doesnt like me all that much, but i never wrote, nor did that. i highly doubt a 12% bottle of peroxide would make enough 90% for that to even happen at all, nor would i have the means to distill to that concentration and keep it from decomposing down to 60-50% where it is considered stable under standard conditions.
I'm glad you're still healthy, jpoopdog, and that your curiosity and drive to learn are still healthy too.
A comma is not the same as a period.

Hydrogen peroxide can never be used like a solid oxidizer. It is very unstable and will react with most organic compounds and transition metals.

The word catalyst does not have an "i".

A catalyst only changes the speed of a reaction. They cannot be used to make energy out of nothing. 2 molecules of H-O-O-H decompose into 2 H-O-H and 1 O=O. This reaction gives off energy and heats the higher concentrations to steam and oxygen gas. You would have to add a very large amount of energy if you wanted to break the O-H bonds and make O-O and H-H bonds instead. This would also be stupidly redundant, as you would then be burning it and making it back into water.

Benzene is not a peroxide, it is an aromatic hydrocarbon.

Expoxy has epoxides in it, not peroxides. An epoxide is a cyclic ether that acts as a good electrophile in the polymerization of epoxy.

Sulphuric and nitric acids are liquids, while hydrochloric acid is a gas.

The reaction with the sulfur/carbon you mentioned earlier was most likely the oxidation of sulfur to sulfur dioxide. It's a foul smelling gas, but fairly useless. Why would you add the sulfur if you were trying a liquid oxidant? The sulfur is mainly to form a liquid phase and greatly speed up the reaction.

H2O2 will most likely not oxidize HCl. It's not powerful enough of an oxidizer. This will however work with the larger halogens as the X-H bond isn't as strong. HCl acid is aqueous. It has Cl- and H3O+ ions in solution. With a stronger oxidant it is oxidized to the non-aqueous chlorine gas.

As I said earlier; please never try to talk about chemistry ever again. I don't believe you said a single correct statement in any post.

And this can also make diamonds if the purity is at least 90%...
how so?
also, i was wrong about the hydrochloric acid, it seems that the stuff i always use has some kind of agent in it that decomposes h202, or allows the hcl to react with it.anyways, i got a 12% jar of h202 and distilled it, then added it to some charcoal sulfur mix in the proportions 10/3/2 and when i lit it it exploded the jar it was it with a big bang plus made a large fireball and sprayed sulfury charcoal mud everywhere, and it wreaked.

but still, i dont understand how 90% can be used to make diamonds, do you mean the heat which it can generate, and the pressure to melt and compress carbon?
I was joking, most of the stuff you said sounded fake
and the heat it generates is way too little along with the pressure it needs to make diamond

a different method is to simply boil out the water in the Hydrogen peroxide solution. Same result - just faster and less wasteful on the salt. I prefer to use my salt on french fries and the like... Otherwise great -ible and keep up the good work. And invest in a hot plate, THEY'RE WONDERFUL!
If you're going to do this be very very careful not to boil off the peroxide because peroxide gas is highly explosive.
if you put a bag over it while boiling it do you think you could get a condensed peroxide gas?
No. There is no such thing as condensed gas. Gas turning to liquid is condensation. A gas condensing, means it turns to liquid. So boiling condensed gas is even more of a confusing oxymoron. What's a more useful answer is that when you boil it you boil both water and hydrogenperoxide. And since they suggested boiling as a method, I assume that hyrogenperoxide isn't very volatile and the vapors boiling gives off are mostly those of water.
steam/vapour but not a distinguishable liquid.
The only way to boil H2O2 without it decomposing is to use vacuum. Your assumption is wrong. Take a couple of semesters of college chemistry or read some books, not the drivel here.
no, everyone listen up, hydrogen peroxide decomposes in the presence of energy, aka heat or sunlight, if you heat it up it will decompose into oxygen and water, you cannot make peroxide gas by boiling it away , because boing it with destroy it.

also that is true it does boil at 150c, but it would decompose under normal conditions before ever reaching that tempurature so you would get peroxide gas, just not alot, , and not nearly enough to condense into a usable liquid
Does that even work? If the freezing point of water and hydrogen peroxide are close to the same, I'm guessing the vapour pressures are similar, so you're just getting equal proportions of water and hydrogen peroxide boiling off...No increase of %
