Water Azeotrope

The relative volatilities of cyclohexylamine and morpholine in dilute aqueous solution have been measured in the temperature range 150 to 300 °C at the corresponding equilibrium vapour pressure of the solution. Cyclohexylamine strongly prefers the steam phase while morpholine has a relatively volatility close to that of water. In both cases an azeotrope of the amine and water, with a vapour pressure higher than that of either component, must exist; however, with morpholine and water azeotrope formation only occurs above 175 °C. The concentration dependence of the distribution between the steam and solution phases of both amines is explained in terms of their partial ionization in solution.
