WebIt’s well known that the ionic liquids have the highest boiling points with no hazards. So you have to select the suitable ionic liquid for your reaction in order to make it faster and get an... WebLiquids boil when their vapour pressure becomes equal to the external pressure. Normal atmospheric pressure is 101.325 kPa. Compare that with the figure we have just got for the total vapour pressure of a mixture of water and phenylamine at 98°C. Its total vapour pressure is fractionally higher than the normal external pressure.
