Distillation - University of Massachusetts Amherst

the atmosphere the applied pressure equals atmospheric pressure (1 atm = 760 mm Hg)). For cyclohexane, this occurs at 81 C. The boiling point (BP) of cyclohexane therefore equals 81 C. The definition of the boiling point of a liquid in an open container then is the temperature at which its vapor pressure equals atmospheric pressure.
