Before a long time ago i bought a 1L of propylene glycol.
It is used as the liquid for the electronic cigarettes, and i was wondering how pure it is and if it can be safely nitrated to something, and if it's
product it should be also safe (I guess propylene glycol dinitrate )

If its fit for human consumption then I would guess it to be pretty pure.
Best reference I could find for what you are proposing is:

I saw in wikipedia that it is really toxic

Ethylene glycol is the toxic one. Propylene glycol is relatively harmless.
Look again:

A 0 under health hazard that's really harmless! Even table salt has a 1 rating. This seems like a rather harmless compound so don't worry about
working with it. Although you shouldn't asume that the nitrated form is harmless for example urea is safe yet nitrourea is explosive.

He was meaning the dinitrate guys and yes, the wiki article says it's really toxic... there's better things to do with you propylene glycol, maybe
attempt a propylene carbonate or polypropylene glycol synthesis?

I second what deltaH said I think that you should keep the nitrating for more common things. although you should nitrate a few grams.

Apparently upon decomposition the dinitrate give off hydrogen cyanide gas as well. I would personally steer clear of the stuff, and stick to trying to
synthesize some polypropylene carbonate! (As deltaH mentioned). I'm actually looking to purchase some PG myself to make the carbonate as the synth
looks very simple. Very exciting possibilities for the amateur chemist with that stuff!

It gives off HCN! I do not want to deal with that. Most explosive are dagerous, but some like beryllium azides and this are just scary. They shoot out
toxic materials on detonation/deflagration!

Where the polypropylene carbonate used for ?

use it to make propylene carbonate, which in turn can be used to make alkali metals!
