Changes in azeotrope composition
Thread Content
Ethyl acetate and water form an azeotrope at normal pressure; if the pressure is increased, will the azeotopic temperature and composition change, and what is the trend?
Can an azeotrope still be formed when the pressure changes? . . ? If possible, an increase in pressure will definitely raise the boiling point. The azeotrope composition will definitely change as well!
For systems that form azeotropes, there is 1 degree of freedom; at a constant pressure, both the temperature and the composition are fixed. When the pressure changes, both temperature and pressure change.
Azeotropy refers to the condition in which the composition of the liquid component in the solution is the same as that of the vapor phase obtained during distillation. With pressure changes, the azeotrope still exists; its temperature will increase, right?
