Azeotropic distillation

  1. Mar 28, 2009 #1

    I am curious on how azeotropic distillation works. I know it has to do with the gas law, PV=nRT but I would like to know in depth analysis how this process works.

    I have organic 2 lab final coming up (this Tuesday) and it may happen we might be asked to explain how azeotropic distillation works.

    The experiment we did was synthesis of Sulcatol (6-methyl-5-hepeten-2-ol). I transferred the crude prepared Sulcatol to a round bottom flask connect to thermometer and manometer (to measure the pressure). Also, pump was connected to the set-up to generate pressure, and I heated the crude sulcatol till it evaporated. Can someone help me in explaining what is going on in the pressure-boiling process?

    Also, I would like to know why the manometer reading is in negative not positive?

    Please let me know if my method of submitting the question is incomplete. I am new to the forum.
