<PICT:0970390/C1/1> A method of storing ozone comprises dissolving the ozone at a temperature below - 95 DEG C. in a fluorinated hydrocarbon which is liquid at that temperature, for example a fluorochloro-methane, introducing the resulting solution at said temperature into a pressure-resistant storage container, closing said storage container, and allowing the temperature of the solution to rise to room temperature, characterized in that the storage container comprises a glass vessel, into which the solution is introduced, disposed within a pressure-resistant metal vessel, and in that the difference in pressures exerted on the inner and outer surfaces of the glass vessel during the rise in temperature and thereafter at least until said ozone is required for use is kept at a value below that necessary to fracture the glass vessel, for example by providing the glass vessel with a valve, preferably also of glass, so that gas may pass from within the vessel into a space between the metal and glass vessel. The inner surface of the metal container may be coated with a synthetic plastics material which is substantially inert to ozone, for example polytetrafluoro-ethylene. In a modification, the glass vessel is sealed after filling, and thereafter a gas, for example oxygen, helium, argon, nitrogen, or a fluorinated hydrocarbon is introduced into the space between the glass and metal at a rate predetermined to maintain the pressure differential. The Figure shows a suitable container for the exercise of the invention, in which a glass vessel 1 fitted with a ground glass ball valve 3 is disposed in a metal container 5. To obtain the ozone for use, the valve 8 is opened, whereupon the pressure differential will increase and thus the glass vessel will burst. Specification 952,230 also is referred to. |
