bullshit or fact?
SOURCE: http://williestop.tripod.com/Highexplosivespictorials/HDN.ht...
Measure out 50ml of water and pour it into a 200ml flask (or similar device). Weigh out 15g of hexamine and add it to the flask with water. Swirl the
flask until all of the hexamine is dissolved in the water. Prepare and ice bath and stick the flask containing the hexamine solution in it. Measure
out 15ml of 70% nitric acid in a graduated cylinder, then pour it into a 20mm x 150mm testtube. Place this in the ice bath as well. Once the hexamine
solution and nitric acid are cold, pull the hexamine solution out of the ice bath and dump in the nitric acid. Begin swirling. Once it reaches room
temperature, place it back into the ice bath and swirl it around in there for a good 60 seconds. Quickly filter it out. While you're waiting for the
liquid in the filter to drain, add ~100mls of water free acetone to the 200ml flask. Swirl it around to grab the remaining crystals of HDN. Once all
of the water is out of the filter, pour the acetone into the filter. This is to remove the water and excess acid. Place the filter some place to dry
and then store this in a tightly closed container perferably with a dessicant. I used this synthesis 5 times and averaged out the yeild. Getting an
average of 14.58g which comes to a 51% yeild
everyone said if we could not nitrating hexamine with dilute nitric acid because of the water contained in it, then why is there an article like this?
don't laugh me, please

Could you not have put this in one of many of the hexamethylenetetramine dinitrate threads?

who said that ?
of course you can "nitrate" hexamine with watercontainig HNO3 - if it doesnt contain water you failed at the synthesis  and get RDX 
...for the hexamine MONOnitrate you just need around 30-50% HNO3 (afaik)
and yes HDN reacts with water (decomposition)...but the acid is strong enough to nitrate the HDN and the hydrolysis (?) is slow enough that you can
nitrate HDN and wash it with water without having high losses in yield...
btw is seems that your synthesis doesnt work really good for you...i read much texts where it was 1g hexamine + ??g 70% hno3 = 1.5<2g HDN...dont
know if thats correct....

oh man, im laughing you and im abit sorry about it
its a synthesis, you want to use just enough water for the hexamine to be dissolved in it
much easier to just dump the solutions in 2 plastic bags in the fridge and have it laying around for a day, then pour it together in a beaker in a ice
bath, wash, and perhaps wash with acetone aswell.. recall something about this makes drying much easier
