    O2 Oxygen Gas High Purity Gases CAS 7782-44-7 , UN1072 Oxygen Tank

    O2 Oxygen Gas High Purity Gases CAS 7782-44-7 , UN1072 Oxygen Tank


    Description:


    At standard temperature and pressure, oxygen is a colorless, odorless, and tasteless gas with the molecular formula O2.


    Oxygen, which makes combustion possible and supports life, also constitutes about a fifth of the atmosphere. It is a pale blue, transparent liquid that is slightly heavier than water at temperatures measuring below 300 °F. Every material that is flammable in the air burns much more vigorously when exposed to this gas. Some combustibles, such as grease and oil, burn with almost explosive force if ignited in this gas. However, pure oxygen itself is not flammable.


    At standard temperature and pressure, oxygen is a colorless, odorless, and tasteless gas with the molecular formula O2, referred to as dioxygen. As dioxygen, two oxygen atoms are chemically bound to each other. The bond can be variously described based on level of theory, but is reasonably and simply described as a covalent double bond that results from the filling of molecular orbitals formed from the atomic orbitalsof the individual oxygen atoms, the filling of which results in a bond order of two.


    Oxygen storage methods include high pressure oxygen tanks, cryogenics and chemical compounds. For reasons of economy, oxygen is often transported in bulk as a liquid in specially insulated tankers, since one liter of liquefied oxygen is equivalent to 840 liters of gaseous oxygen at atmospheric pressure and 20 °C (68 °F). Such tankers are used to refill bulk liquid oxygen storage containers, which stand outside hospitals and other institutions that need large volumes of pure oxygen gas. Liquid oxygen is passed through heat exchangers, which convert the cryogenic liquid into gas before it enters the building. Oxygen is also stored and shipped in smaller cylinders containing the compressed gas; a form that is useful in certain portable medical applications and oxy-fuel welding and cutting.

    Applications:


    Life support and recreational useAn application of O2 as a low-pressure breathing gas is in modern space suits, which surround their occupant's body with pressurized air. These devices use nearly pure oxygen at about one third normal pressure, resulting in a normal blood partial
    pressure of O2.
    IndustrialSmelting of iron ore into steel consumes 55% of commercially produced oxygen. In this process, O2 is injected through a high-pressure lance into molten iron, which removes sulfur impurities and excess carbon as the respective oxides, SO2 and CO2.
    ChemicalEthylene is reacted with O2 to create ethylene oxide, which, in turn, is converted into ethylene glycol; the primary feeder material used to manufacture a host of products, including antifreeze and polyesterpolymers.
    OtherOxygen is used in medical applications, metal cutting and welding, as an
    oxidizer in rocket fuel, and in water treatment.
