Ozone Tamed i Elusive gas now available from Matheson in cylinders for wide variety of applications The Matheson Company has developed a practical method of storing ozone in cylinders for convenient laboratory use. Our East Rutherford, N.J., plant is now packaging ozone, in stainless steel cylinders, mixed with "Freon-13".® The cylinders have facilities for withdrawing ozone in several ways and will permit storage of the ozone-" Freon-13" mixture for long periods. The mixture permits recovery of up to 15% mol ozone in contrast to the 1 % to 3% concentration usually obtained from ozone generators. Important Applications — Our method for concentrating and storing ozone has many advantages over other sources, and provides an important new tool for the laboratory chemist. Matheson ozone can be conveniently used as a strong sterilizing agent; water purifying agent; food preservative; and extremely energetic oxidant; a destroyer of odor-forming, toxic and corrosive compounds; an agent for the treatment of glazing and sizing many plastics; for the manufacture of perfume, camphor, etc. Dissolved Ozone Versatile — The Matheson method of packaging dissolved ozone permits its use as (1) a reactant in the liquid solvent phase, (2) as a gas mixture of constant composition by withdrawing the material as a liquefied mixture and vaporizing it, (3) as a gas by withdrawal of the vapor, as needed, from the cylinder. In the latter case, the ozone will vary in composition as it comes out of the "Freon-13" solvent. As it is used, the "Freon-13" concentration will increase slightly. Shipping and Storage — Matheson ozone is shipped in stainless steel cylinders of 1 liter volumetric capacity. About 10 to 15 liters of ozone are available from cylinders on a 100% basis as measured at atmospheric pressure and room temperature. The cylinders are shipped in a returnable, insulated carboy, packed with dry ice. The ozone can be stored for several months using refrigeration. It can be stored almost indefinitely if refrigerated at liquid oxygen temperatures. Because the composition may change with time and storage conditions, we are offering a kit to determine the exact composition at any time. ("Freon-13" is a trademark of E. I. DuPont de Nemours & Co.) Write for Ozone Data Sheet — A new Data Sheet containing physical constants, description of the gas, chemical properties, precautions in handling, regulators and controls, etc., is now available. Further inquiries on Matheson Ozone and its applications are invited. For Data Sheet, Price List or other information write to Technical Department, The Matheson Company, Inc., P.O.
