Oxygen phase diagram

  1. Jan 18, 2014 #1
    i need to know what pressure oxygen will liquefy at under various pressures but i can't find a phase diagram anywhere
    any link phase diagram that shows pressures 0-50 atm would be useful

    i searched for triple point of oxygen
    this contains a phase diag

    You don't need the whole phase diagram. All you need to know is the equilibrium vapor pressure of oxygen (as a function of temperature). You should be able to find this using google. If not, look in the handbook of chemistry and physics or the chemical engineers' handbook.

    Try fluid properties at NIST.
