Subbing erythritol for pentraerythritol?

Could you do this?

I am wondering if you could perform this exactly as is but using erythritol instead of pentra but the same amount as pentra. http://www.metacafe.com/watch/8631529/synthesis_of_petn_with...

Or is there a completely different way of going about it

It is called ETN instead of PETN and is a widely discussed within hobby circles.

Thanks ^^ that answers my question then. So instead f adding erythritol to sulfuric acid/AN the two powders are pre mixed and is added to the acid. The is very in depth description too. I want to eventually be able to do that relatively safely and know what I am doing so just reading bits at a time and doing other stuff for now. Even though erythritol is different from pentra, they act the same in the production is what I see there.

I also saw the recrystalization process. So no heat was used in that, but why did the guy who had the hand accident use heat in recrystalizing the etn from ethanol???

Also just an fyi the compound is called PENTAerythritol not PENTRAerythritol.
