2008-7-29 · 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. Note that under vacuum, the BP of a liquid will be lower than the BP at atmospheric pressure.
