Non-aqueous Hydrogen Peroxide
Anyone have ideas for a suitable solvent to use to make H2O2 solutions without water?

I should have said, I need something a bit higher-boiling.

I recall something about evaporation of a 30% solution under reduced pressure and 40 or 50*C to afford a residue that consists of 98% H2O2. Perhaps in
Inorganic Syntheses?

The 98% I have; I'd like to be able to make a lower concentration solution in a solvent other than water, and relatively high boiling.

Sorry, you didn't specify this. In either case, 98% concentration is prepared as per Brauer.
As for the non-aqueous peroxide, have you considered tBuOOH?
EDIT: Sorry again, should have checked bp (=35*C) before commenting
Why do you need it higher boiling? What is your intended use?

Yeah I basically fucked this all up. I'd like to make a non-aqueous solution of H2O2, not a non-aqueous peroxide.
Yes, the 98% was produced per Brauer.

I am doing an experiment that calls for 58 g of a 35% hydrogen peroxide solution. I already have 17.5 % hydrogen peroxide, so my question is, can I
use the 17.5 % instead of the 35% but just use a greater amount, and if so what amount?

Really dependant on the experiment. Will the additional water affect your rection?

It will not have any affect on the reaction.

Well, then I think you answered your own question.

So if the extra water will be eventually filtered out of the final product, then I can just use twice the amount of 17.5% ?

Yes, you can.
Gutter, you must also consider the fact that you can't heat H2O2 much above 100°C, because it will rapidly decompose/explode.
