IPN

[da man]

I read the synthesis for this explosive on megalomania's site, and it seemed very interesting even though it isn't very powerful. It is made from only 60% nitric acid so i don't have to distill my own, which is a big plus.
However i don't understand the synthesis on mega's page. It says that you are to distill a mixture of nitric acid and isopropyl alcohol, but wouldn't this distill over the nitric acid and water also, making the isopropyl nitrate pretty dilute?
And also, just curious, why does the isopropyl alcohol have to be saturated with urea, Is it something to do with nitrogen dioxide forming, and wouldn't it waste alot of the nitric acid forming urea nitrate?
So does simply distilling isopropyl alcohol (saturated with urea) with nitric acid in the ration of 1:2, at about 100*C obtain a good product?
Any information on this explosive and its synthesis is appreciated, and has anyone here made it sucessfuly?
Thanks.

Sorry for my ugly english :)

I think, at 100°C nitric acid will oxydate isopropyl alcohol and you get some nitroform (trinitromethane). For example, look at the patent 4,122,124.

I am make IPN in 1 l beaker flask into which was boot 2 funnels with bottom water outlet subaqueous, dose I am :
1. flow 75% IPA with 10% urea
2.flow 65% HNO3
ratio about 1:1.5 by volume
in bottle was 400-500 ml 40% HNO3 with 15 % urea
temperature between 102-108 C
distill IPN with aqueous solution HNO3
yield was only 65-70% on IPA (500 ml IPA = 440 mlIPN).
