What is the effect of pressure on azeotropes?

The effect of pressure on azeotropes can significantly alter their boiling points and compositions. Increasing the pressure typically raises the boiling point of the azeotropic mixture, which may change the vapor-liquid equilibrium and potentially allow for separation of components that are otherwise inseparable at lower pressures. Conversely, decreasing the pressure can lower the boiling point and may lead to a different azeotropic composition. Overall, pressure changes can shift the characteristics of azeotropic behavior, influencing separation processes in distillation.
