Some dry cleaners use SC-CO2, perhaps you could use

Hmm...
For curiosity's sake, could you use liquid CO2 instead of supercritical CO2 for such a nitration?

By chance liquid CO2 (what is usually found as solid sublimating dry ice) is already supercritical when under liquid form

| Quote: |
With N2O5 contents of more than 50%, the nitrating bath becomes difficult to operate because of the difficulty of dissolving N2O5 in nitric acid (at
