Concentrating Hydrogen Peroxide from 3% to Above 90%

Fractional vacuum distillation is used to concentrate hydrogen peroxide from the 3% version you can get at any store to the rocket fuel concentration of above 90%. Equipment list and some more details available at antenna-theory.com/high-test-p....

A question and 3 suggestions 1 When you clean your still make sure you only use deionized water, most metal ions will catalytically decompose h2o2 to water and oxygen and generate a lot of heat which can lead to a thermal runaway detonation of your product, which can and will shatter glass, and in addition lead to a significant loss of product, I recommend you rinse all of your glassware with deionized water like 6 or 7 times 2 do you have a thermometer attached to your still head? tempeture readings tend to be much more accurate at determining the composition of a distillate than density measurements. You can get the Hydrogen Peroxide water system charts by an easy Google 2 since you have distallition equipment already I wouldn't bother with the open top breaker arrangement you lose a lot of hydrogen peroxide, yes I know its a pain in the ads to run a distillation on that amount of fluid but your yields will be much better.

[@raptor4916]

[@EdwardTriesToScience]

The distillation is done under vacuum so it vaporizes before decomposing

[@blaquerDP]

@@EdwardTriesToScience the first part though is what? Basically boiling it. I'd be surprised if that H2O2 had a concentration of 30% - The difference in density is probably due to stabilizers added to the commercialy available 3% peroxide. Vacuum distillation though should work but why heat it first? Stupid.

[@EdwardTriesToScience]

@@blaquerDP He's evaporating, not boiling, which can easily bring peroxide to 30%. Vacuum distillation would work to bring 3% to 30%, but you would need to use larger flasks, and have to distill the water over, re-pressurize the system, swap receiver flask, then vacuum it and then heat it again. Too labor intensive. The point of the distillation is to get rid of the stabilizers and impurities, not concentrating it. Don't try to win an argument on a topic you don't understand.

[@blaquerDP]

@@EdwardTriesToScience Son, do you know that H2O2 decomposes below 150C right? Even if he's heating it to 80 C... I know more than you do on the topic but you probably watched 3 episodes of NileRed and think you're the best chemist on the planet. For you NMR is probably a "dank kush strain" and whenever you see a spectrum you think its a faqin moutain drawing done by some kid. You also never worked in a lab if "using larger flasks+re-pressurizing then vacuum+heating" is a lot of work, that takes literally seconds with experience - Unless one flask more to wash is too much work for you princess. Also do you know what the stabilizers are and how they behave? From your reply I don't think so...

[@EdwardTriesToScience]

@@blaquerDP Well why don't you try doing it then if its so easy? And yes I don't understand how stabilizers work but at least I'm actually doing research on how they work. And yes peroxide does decompose but at low temperatures and in a clean container the decomposition is negligible. Theory is useless without backing by evidence so why don't you do it and make a video report about it?

I looked at my hand nearly shit myself when I saw the skin was instantly bleached white as chalk. I really thought I had F's my hand over badly -- but with some rinsing in cold water the pain quickly subsided & the color came back.

[@peterb7615]

In an innocent sense you could use it as a cleaner for organic stains and it's good for removing mold and you could simply dilute it to a lower range of 1-3% and use it for the usual stuff. In a less innocent sense you could use it to make an advanced party favor. though I image your supply is gone after a year at this point

[@chiraldude]

You can do this but it is dangerous. Above 60% or so H2O2 is capable of runaway decomposition. I worked at a company that was developing a H2O2 sterilization system that took 60%, concentrated it to 95% then flash evaporated it into a vacuum chamber. Every 20 cycles (or so) the solution would "explode" before reaching 95%. Not a problem as it was only 20ml and in a metal chamber but, the point is that we started with a fairly pure solution from an industrial supplier. Drug store peroxide comes with unknown amounts of additional "stuff" that could cause all sorts of problems. I recommend using a face shield and thick clothing so that when a batch does explode, you won't have to pick the glass shards out of your skin!

stabilizers stay in the original solution. some peroxide is transferred to the secondary container, while water evaporates faster, increasing the concentration over time.

using a fractioning column makes sense after thinking about it awhile. and its leading to finding the bp's of water & H202 at -28" of vacuum. overall you've been inspirational with a demo of your knowledge for those of us wanting the conc'd result and unsure how to get it. the items list via the 'antenna' link was well done. lastly , after searching for precision hydrometers and learning their high price the method you use to get %'s by just weighing a measured volume of H202 is smart when a ballpark value is good enough

[@HicSvntDracones]

Never had much luck evaporating it, but I have concentrated peroxide using the freezing method, h2o2 freezes at a little lower of a temp than H20, meaning the water will freeze first, but they are very close in temp, so you put it in the freezer until Ice crystals just start to form, like a slushie on top of the water, strain them out, and keep repeating. Granted, can't get anywhere near 3%, use to do this when I ran out of 20 Vol peroxide for bleaching my hair, works quite well.

The problem here has been brought up already by a few commenters. I have worked with H2O2 up to concentrations of 57%. It starts to decompose in small amounts immediately after it is made. Even a 3% bottle will bloat if left in a warm environment. Heating H2O2 causes rapid decomposition and in an open air beaker the concentration of H2O2 after heating, although a smaller volume, is going to be quite low. At one point he says the density is "1.1" but doesn't show how he arrived at that. Something fishy is going on here in the beginning. I'm sure of it.

Thank you for making a great DYI on concentrating 3% H2o2. I love the disclaimer! Now I see why it pays to just buy the 30% rather than make it. If you used a double boiler so that you did not exceed 212F (or 100C for the rest of the world) would that be too hot or to close to the boiling point? I thought 90% H2O2 was more unstable and reactive and that anything over 50% was to dangerous to handle, that was very enlightening to see. Didn't the Germans use that for the ME 163 rocket plan during WWII?

[@peterb7615]

I don't know if the Germans used it, but it was used in the Gemini program for some of the thrusters (changing position and direction I believe, not for takeoff). 90% H202 is not unstable with modest precautions. In open containers you can throw silver in there and it reacts fairly violently, but not an explosion. I have another video showing that

[@fredjones2980]

Normally it isn't that unstable, however it is much much more stable when you buy it from the store. If you ever look at the active ingredients it says "stabilized hydrogen peroxide". What this means is they added sodium citrate, sodium phytate, or some other carboxylate stabilizer that slows down the decomposition by quite a bit. Since the melting point of these stabilizers is quite high you can't remove them by boiling. Even with these stabilizers its highly recommended to have clean glass ware. www.ccohs.ca/oshanswers/chemicals/oxidizing/oxiziding_hazards.html Over 91% hydrogen peroxide by weight (without stabilizers) is considered a class 4 oxidizer. Granted it likely wont self explode if not mixed with a fuel. Ammonium nitrate is considered a class 2 oxidizer and theres this great ansu (AN and sugar) vs anfo (AN and diesel/other oil fuels) video on youtube:kzbin.info/www/bejne/g5mrgISrrtpnZ68.

[@Aim54Delta]

@@suprememasteroftheuniverse Ammonium nitrate can and does detonate on its own under the right conditions. I am of the opinion that this cache of nitrate was deliberately 'abandoned' and was being used (or planned to be used) for munitions production. If you ask me, it was a stockpile taken out by Mossad. A missile isn't necessary. There again, there is a picture of some people welding on a door that is suspiciously identical to the door of that warehouse. So, there's a decent probability that the fire was started by classic TCN labor snafus.

Yo. Kool video but, I had an extremely hard time trying to hear and understand you. You had your audio way too quiet and you were mumbling WAY way too quiet. I did get that H2O2 takes more energy to evaporate than H2O which is new to me.

Hey Peter! Thanks for posting this - I had no idea it was that simple to concentrate it that far! You have my sympathy re: so many comments about either just boiling it down or freezing to concentrate it. I told some of those people about how azeotropes complicate the process, but the questions didn’t end! Thanks again - off to watch your demo.

All you need is a glass jar in a freezer and another glass jar to pour the pure peroxide after you filter it out,from the frozen water🤷

[@johnh8546]

You can just concentrate it yourself. Water boils at 212°f hydrogen peroxide boils at 302°f so just get the solution to 250°f and keep it there. Of you know the volume going in and the volume coming out you know the concentration. If you over concebtrate add distilled water if under boil it more. There you go.

[@firstmkb]

It forms an azeotrope with water, and the peroxide will begin decomposing before all of the water is gone. Similar thing as distilling alcohol/water mixes. Alcohol boils first, but it always brings some water with it.
