Nitrocellulose via RFNA


So, I was able to distill about 300 ml of >%95 nitric acid. The acid is yellow colored (duh) and it fumes nitrogen oxides. White fumes as well as the occasional reddish fuming. So anyways, I was wondering about using this for Nitrocellulose synthesis. I read somewhere about it not being effective with the classic Sulfuric Acid route. Should I dilute it to %70 nitric acid? If so, I can't seem to find the molarity of RFNA which I would need to do the dilution. Or should I just use RFNA and my concentrated Sulfuric Acid and use the classical method of cellulose nitration? Thank you for your time.

Well, it's rubbish wherever you read it ...

Adding an equal volume of conc. H2SO4 to your RFNA will give a more complete nitration and a better product!

Depends on what he wants it for. It can be over-nitrated for certain applications.
