Erythritol Tetranitrate


For those who don't know, Erythritol is a new low cal sugar subsitute.
http://www.sciencemadness.org/scipics/erythritol.gif

i used the pcedure posted on E&W by AXT

33ml of H2SO4 were added to 20g KNO3, they were blended, set in a salt ice bath and allowed to cool to about 10C. 5 grams of Erythritol were added in portions, the temp didn't rise above 15C. It was stirred alot and let sit in the ice bath for 30 minutes. the product was filtered and recrystalized from acetone. Final yield was a very embarassing 0.8g!

argh! longer nitration time, i thought. So i did the same thing again but let it go overnight. next morning i filtered, purified, etc. yield was 8.5g from 5g Erythritol. now thats wht im talkin' about! thats 1.7g ETN per g Erythritol.

.5g was pressed into a straw and taped to a block of wood, set to be initiated with .2g HMTD.

The block was placed on the ground, fuse lit, and a large rusty metal bucket placed on it to cover it, a chunk of cinder block was placed on the bottom of the bucket.

the bucket was knocked over, the bottom was 40% ton off, and there was an indent in the shape f the cinder block on it.

the piece of wood, fairly hard stuff i say, dented in around 7mm or so

i plan to do more experimention, perhaps some power comparisons, fueling, etc. i'll be sure to let you guys know about anything worthy.

All well and good, but has Erythritol been approved for use here in the UK? I have searched the net, and online health stores like GNC etc, but cannot find it at all. Some have xylitol / sorbitol, but no one carries Erythritol. Are sorbitol or xylitol potential candidates for nitration?

erythritol is not available yet as sugar substitute in old europe, should be approved in this year, then will take some time till it will be distributed, so all the other sources are non OTC at now.
Sorbitol and Xylitol are good nitration candidates, as well as mannitol, dulcitol, lactose..
each one of them has its problems and is good points but most of them are easy to nitrate!

I hear from E&W, this is a powerful explosive, does it have to be detonated?....or is there another way of setting a charge off...I'm guessing this is a secondary explosive...therefore I suppose it needs to be det to be set off...

you want to set it off?
you can hammer it, warm it very fast up to 200°C, grind it, or stuffs like that..

sorry, i kept forgettingto post these. the target was a thin steel AOL CD tin that came in the mail. .5g of each explosive initiated by .2gHMTD, all pressed in astaw in configurations as close to identical as i could do.

PETN's higher bristance is clear, the hole is cleaner, less deformation in the plate and the hole is close but apears a little bigger. there is also 9 sections of metal protrudeing from the exit side. there are only 7 on the ETN one.

the other day i found a can of silly string in my house and i decidedto blow it up, i used an unmeasuredamount of ETN in a straw, musta been about .3g or so. it blew a nice hole in the can, which was unused. and there was huge chunks of green silly crap all over.

So I made a batch of white powder that SHOULD be ETN. It had condensed drops of liquid in the flask of ETN after a day storage. When I dried it, it melted earlier than the 60 degrees I expected. Is there water in it?

I successfully produced ETN using drain cleaner sulfuric acid (92%) - in excess and NaNO3 (NH4NO3 dissolves even better) and keeping the temperature at about 20-22C when adding the erythritol, with careful stirring. It is than precipitated with cold water, neutralised with NaHCO3, washed again, and recrystallized with ethanol-acetone mix (I choosed 4:1 ratio).
