Nitration of nitric esters in mixed acid/methylene chloride:

If I'm reading this right, the removal of nitrous acid from mixed acid via compressed air and the addition of urea should allow for the production of
solid nitrate esters without the lengthy purification step.
However, they don't provide any experimental, and the substance I am most interested in (MHN) is specifically called out as causing problems. They
report a 23% yield (as opposed to 89% for ETN), but "discarded much material out of safety concerns."
What were they? How is this best done? And would inositol hexanitrate pose the same difficulties?
