A process for the explosion-proof storage of nitrous oxide

Abstract

A process for the explosion-proof storage of nitrous oxide in the liquid phase in a container comprising filling the container with nitrous oxide and an inert component selected from nitrogen, oxygen, carbon dioxide, water, argon, helium, krypton, xenon and mixtures thereof, and keeping it at a temperature of 190 to 273 K, wherein (i) the container has in all three spatial directions an inner distance between two opposite interior walls of ≥10 cm, (ii) the concentration of the inert components comprises 2 to 20 wt.-% in total, based on the nitrous oxide in the liquid phase, and (iii) compounds selected from—gases having a flammable range with air at 293.15 K and 101.3 kPa abs,—liquids having a flash point of ≤366.15 K at 101.3 kPa abs, and—mixtures thereof are kept at 0 to 2 wt.-% in total, based on the nitrous oxide in the liquid phase.
