I have some sodium carbonate perhydrate based laundry detergent,
> 30% sodium percarbonate, remainder sodium carbonate and possibly some bulking agent.
Just to experience how powerful an oxidiser anhydrous H2O2 is,
I would like to isolate a SMALL ammount, less than 1 ml per 'run'
(definitely open to suggestions here, negligible experience with 'energetics')
I have made Mn2O7 unknowingly twice, and deliberately a few times,
so no warnings please UNLESS it is significantly more hazardous than Mn2O7.
I expect vacuum distillation will be required due to the potential for explosive decomposition .
This will almost certainly be the most (deliberately) dangerous experiment for me to date,
preparations may take quite a while so time for detailed investigation first.
(not least of which will be a blast shield)
(the same blast shield that I now realise is essential to continue 'transparent sodium' and 'coulombic explosions' experiments
(I am still dreaming of a fume hood, how nice to be indoors in winter, and every other rainy/cold/windy season here in UK.....)
I am just starting some research, my favourite, wikipedia first,
my first thought is;
"this needs a micro-scale procedure, that only people that do not want to, have the knowledge to safely scale it up"
and I am out of my depth !
any pointers ?

A bit of reading suggests that some solvents (not discovered which yet) can take up some of the H2O2 from the percarbonate
without dissolving the sodium bit.
Presumably you then have a loaded solvent with which to oxidise something else that dissolve in that solvent, and no water.
If you really really really want it deleted, remove your posts and i'll toast mine too.Sulaiman - 18-4-2016 at 11:34
yes, after reading the thread that you pointed to,
my original desire is not satisfied there,
but enough information to get me started.
(thanks aliced25, wherever you are)
for the immediate future I have a lot of electrochemistry to learn.
my dreams of being an opsimath are getting crushed aga - 18-4-2016 at 11:45
Autodidactict opsimathy is a wonderful thing.
I'm almost 50 and started learning Calculus for some reason.
It's never too late to get it all wrong, i say !Sulaiman - 18-4-2016 at 12:22
I will start with the 'Bracken.Tietz.Supporting.Information.pdf' exercise soon,
nice to follow a classroom assignment (I can't believe I just wrote that !)
good to check the actual percentage in the product first, and my quantitative skills.
As a quick 'test' of direct extraction I will have a go with DCM later tonight ...
first I'll mix DCM with 35% H2O2, also Na2CO3, as I do not know what interacts with what !j_sum1 - 18-4-2016 at 14:49
I'm interested
(Ha! another contributor to the thread so I guess that takes it off the delete list.)
I am interested in a cheap otc source of reasonable strength H2O2. 3% at ridiculous prices is the norm around here. I will back away from 100%. I
believe it is nasty and unforgiving.
I have been experimenting with sodium persulfate but with limited success. I have some sodium percarbonate (from brewers' suppliers) but have not
begun to play with it yet.
For those interested, a solution of potassium permanganate is a good indicator for H2O2. H2O2 will reduce it to a colourless solution without
acidification.NedsHead - 18-4-2016 at 15:42
Don’t you have any hydroponic stores near you j_sum? j_sum1 - 18-4-2016 at 16:14
Not that I know of.
Do they sell 30%? I might have to look it up.
Still, it seems like a worthwhile project -- if I can get it to work.NedsHead - 18-4-2016 at 19:22
They sell 50% under the name Oxy Plus by growth technology, a 500ml bottle costs about $15
