Make Hydrogen peroxide from sodium percarbonate(sodium carbonate peroxyhydrate)


I found in supermarket OxiClean which is used as solid source of hydrogen peroxide, it hydrolises in water to produce hydrogen peroxide, it is adduct....Na2CO3 x 1/2 H2O2
It has about 27% hydrogen peroxide....see wikipedia...
Can you help me, how to extract hydrogen peroxide from that?
It would be great :o
I mean to get hydrogen peroxide without sodium carbonate.
It hydrolises in water to make hydrogen peroxide, that is all i know, help...

Why bother? 3 and 9 % H2O2 are available from any pharmacy, real cheap too. Stronger, up to 35 %, you get from eBay, very reasonabe too.

Your Na2CO3.1/2H2O2 can come in handy for alkaline oxidations as such.

yeah i have that in my house used for laundry... is there a plausible way on making hydrogen peroxide from it if some wanted to preform the experiment?

I read up on the wiki page about Sodium Percarbonate and it stated;

"Sodium percarbonate can be used in organic synthesis as a convenient source of anhydrous H<sub>2</sub>O<sub>2</sub>, in particular in solvents that cannot dissolve the carbonate but can leach the H<sub>2</sub>O<sub>2</sub>out of it."

is it possible to extract the Hydrogen Peroxide from the Solvent or once its in the solvent thats it?

No, I can't buy anything from internet, and maximum concentration in my country is 3%, so it is not reliable to buy because it is expensive! This would be cheap.

In the reaction of H<sub>2</sub> + O<sub>2</sub> = H<sub>2</sub>O<sub>2</sub> does the gases need to be combusted?

Jar one with a hose leading into jar 2
H<sub>2</sub>O<sub>2</sub> = H<sub>2</sub>O + O<sub>2</sub>

Jar three with a hose leading to jar 2
2Al + 6HCl = 2AlCl<sub>3</sub> + 3H<sub>2</sub>

Jar 2 with a hose leading into a container with a vent
H<sub>2</sub> + O<sub>2</sub> = H<sub>2</sub>O<sub>2</sub>

lighting the hose coming out of jar 2 reacts the gasses forming a condensate of Hydrogen peroxide? possible or not possible?

They don't react uncombusted.
Even if you combust you are just doing nothing.
No, actually if you used electric arc then it would make h2o2, but h2o2 would instantly decomposse to h2 and o2 because of high temperature(h2o2 decomposses on boiling).
So, H2O2+HEAT=NEVER WORKING, DECOMPOSSING

is there a way to purify Sodium Percarbonate? i done tests with it but i dont have a very good amount of Sodium Percarbonate... mine is about 257g/Kg

1st, why would you want to purify it.
2nd, it is mixed with similar chemicals like sodium chloride and sodium carbonate.

And, when you put it in water did it instantly bubble, if not did you try mixing Mno2 with it?

Yeah it instantly started to bubble, filtered the sollid remains, placed into freezer to cool to leach out any Sodium Carbonate has precipitated due to low temp, then i re filtered and tried the Elephant toothpaste with it... it did kinda work, just very slowly... and i alsoo did put MnO2 into it to preduce Oxygen... but purfying the Sodium Percarbonate so i dont have any fragrance with the Solid or anything that will cause poor quality when i want to use it for the hydrogen peroxide
