liquid

Has been used as rocket propellant. Does not need external oxygen for combustion.

Explodes when heated, severe hazard whenexposed to heat or shock. Narcotic, strong irritantto tissue.

Wash MeONO2 once with H2O then again with H2O containing a few drops of concentrated NaOH to keep it slightly alkaline (litmus). Dry the ester over anhydrous CaCl2, decant it and use it directly. It is possible to distil it under a vacuum with slow and gentle heating, as a sudden rise in temperature can cause decomposition with copious release of nitrous fumes (use extreme precautions and protection). The middle fraction can then be subjected to several freeze-pump-thaw cycles.
