99% formic + 50% H2O2
« on: July 12, 2003, 07:47:00 AM »
If someone had these chemicals at that strength, would one just work out the amount they need to be diluted to get to 85% formic and 35% H2O2 and proceed from there? Assuming the standard buffered performic of course.

I hate variables!

Raf had 50% H2O2 and he used tap water for dilution and just checked density.You must calculate to get the amounts needed.It's easy,at least it was for me.

aqueous solutions

I assume you're talking about aqueous solutions. To make a 85% formic solution, mix 85mL formic per 100mL of the total (i.e., for every 100mL you have, 85mL should be formic, and 15mL water). To get 35% solution from a 50% solution, mix 70mL peroxide per 100mL (i.e., a 100 mL solution would be made up of 70mL peroxide and 30mL water). I wouldn't use tap water... I would use distilled/de-ionized water. Good luck peace

No,density of formic acid and it's solutions is always above 1 and so are solutions of perhydrole you can't use volume here but weight.
Let me do a calculation for you.Let's say you want 500 grams of 35% perhydrole.
500x0,35=175
You need 175 grams of 50% perhydrole
and 500-175=325 grams of water to get 500 grams of 35% perhydrole.All % are weight %

Iff you have 100% perhydrole rafkie is right, else multiply with 2 *loL*

(As in 175*x=350g 50% prehydrole and 150gwather=500g 35% perhydrol)

Could you help swim find a complete procedure using formic acid and H2O2 swim has looked everywhere and cant find anything could you point swim in the right direction?

Procedure for what?

For what? If the actual mixing, everything you need to know can be found above. If you want a procedure using the mixture, UTFSE for "performic acid oxidation"...
