Hydrazine Hydrate 26 %

[a_bab]

I just found a local chem supplier wich can provide HNO3 (80 %), ethylene-glycol, H2O2 35 % and other nice chems. They also sell "hydrazine hydrate 26 %".
Now, I know that hydrazine hydrate is different from the anhydrous hydrazine. So, what could mean 'hydrazine hydrate 26 %" ? A sollution of hydrazine hydrate of 26 % purity, or 26 % anhydrous hydrazine ? And how could I use this ? By boiling it with NaOH ?

Thanx in advance for replies.

What would you get from boiling it with NaOH? If you wanted to concentrate it, read the hydrazine sulphate topic in misc. You would add sulfuric acid to precipitate hydrazine sulfate, and then heat this with NaOH to obtain a higher concentration N2H4.H2O (somethin like that i think..). You could also distill it, but ive heard that this is a very dangerous process, prone to explosion unless it is done in a nitrogen atmosphere.

The topic you mention doesn't make me more clear. I have about 200 grams of [H2N-NH2]2SO4. To obtain H2N-NH2 from it you'll have basicaly to boil the sulfate with NaOH in order to obtain H2N-NH2*H2O, wich is an oily liquid, and boil at 120 degrees Celcius. Then you can obtain from H2N-NH2*H2O some H2N-NH2 by boiling it with NaOH repeatedly. And this is dangerous, as the distilation could lead to an explosion.
So, if I get H2N-NH2*H2O I don't have to turn it to sulfate, as this is the salt from wich H2N-NH2*H2O is obtained !

My question is : how dangerous is to boil A SOLUTION of H2N-NH2*H2O ?
Philou ?
