peracetic acid solution


I found that sodiumpercarbonate is sometimes used also as
a solid form of hydrogenperoxide. Now I react this with a
80% solution of acetic acid where the per acid forms ( am
i correct ? ). I found that H2O2 and acetic acid forms
peracetic acid. So is it not handy using the sodiumpercarbonate
so one can make a good concentrated solution of per-aceticacid ?

The main problem is that the acetic acid and the carbonate react to form sodium acetate wich cannot hold hydrogen peroxide.

It should still work depending what you want to do with it though, you just need to use more acetic acid to account for it. All I would personally find a use of it for is sterilization/surface disinfecting, but I would not want to use a solution with NaOAc in it since it would leave a residue behind. You could purify it, but then it's easier just to start with H2O2 at that point.

I think were is the need I do for doing some experimenting
Ive dissolved some sodiumpercarbonate in 115ml water
and stirr for some time,, Cann you distill to purify to end
up with plain hydrogenperoxide solution:P. For the better
part I doing some time thinking where I can use it for :-)

Believe me, you don't want to distill hydrogen peroxide.

At best he will get the Na percarbonate back while water distills off and at worst he loses his percarbonate by overheating and ends up with Na carbonate. ;):P:D:)

Na percarbonate + water (l)
--> agitation --> distillation
--> Na percarbonate (s) or Na carbonate (s) + water/steam (g)
