Milky NG Problems

For the life of me I can't get the stuff to clear up...

I have left it in a warm water bath with maximum dissolved salt, and a bit of sodium bicarbonate water for a hour + now and it doesn't appear to be clearing up at all.

Should I separate it out from the water and put some AN in it or a desiccant to see if it helps? Leave it out to dry in the open air?

Btw, this was synthesized with 50:50 AN/KNO3 using my own formula. 15g AN/15g KNO3/100g H2SO4(93%)/10g Glycerin at 15-22C. Each addition of glycerin heated it to 22C. Then cooled to 15C again. Maybe I went wrong with swirling it once it was poured into water, instead of letting it separate out slowly?

Ah, darn... I'm just leaving this stuff overnight in salt/bicarb water... I will screw with it tomorrow. Maybe that's AN and KNO3 in there. My synthesis has lots of AN and KNO3 grains in the nitration bath and isn't clear at all. Maybe ill heat up the nitration bath next time to clarify it. :/ That doesn't make sense though, because even if there was nitrate salts in it, the washings should have dissolved it...

Maybe ill just get a distiller and make some HNO3...

There is already a topic about NG, this should be moved.
And yes there is still water in it when its blurry.
One can remove this by plaicng it in a dessicator.

Screwing is not something to do with this substance, be aware of the potential when handling it.

Does NG evaporate too? I have read conflicting things everywhere. Some say it does dissolve in water, some say it doesn't. Some say it can evaporate, some say it doesn't...

Ok, ill suspend some calcium chloride over it and leave the AN in it. It should clear up.

Mods, you can delete this thread if you want.

It does dissolve in water only not so good and slowely.
It can hold water to some extend, that is why its "milky"
It does evaporate, one can smell it when opening a desiccator, only not so fast and it isnt really an issue when drying.

Please don't put CaCl2 in it if that's what u mean.
Just place the open bottle in the container with your drying agent.
Make sure that you wash it after neutralization.
One thing that should be clear is that you do not want any contamination in the NG it's unstable enough by itself.

No, it's suspended over it and sealed up.

What do you mean by "suspended over it"
Please be more clear with your remarks as to eliminate confusion.

Well... Suspended over it. Toss the calcium chloride into a paper towel, rubber band it, then suspend it over it. Worked just fine and the NG cleared right up.

Btw, on another note, anyone know how to get soluble nitrocellulose or insoluble? Just nitrate it different lengths of time, or is there a temperature/time trick, or an acid amount?

Maybe ill just dissolved as much of the soluble out with acetone as possible and hope there isn't too much insoluble.

Dude just pick up a couple of volumes of urbanski.

Or just read the NC section in COPAE in the site library!
