OK. Yes, nitromethane has the same explosive force as TNT as I understand. I powered a moped with almost pure nitromethane, I got it from Nobel-industries where I worked in summertime in my teens. The engine sounded strange but it run OK. I think you need to adjust the ignition if you use nitro, it should have produced more power than it did.

Polyisoprene to branched alkanes, update without carboxylic acids, and possibly less wrong.
  • Ozonolysis, under conditions (RT?) that destroy the ozonides and produce aldehydes and ketones.
  • Hydrogenation of the double bonds, under conditions that keep the aldehydes and ketones.
  • Reduction of the aldehydes and ketones with zinc (Clemmensen or other, I don't know).
Variant:
  • Ozonolysis to aldehydes and ketones.
  • Hydrogenation of the double bonds, aldehydes and ketones.
  • Dehydration of the alcohols.
  • Hydrogenation of the new double bonds.
Better?
