Answer: The boiling point difference is very small ； Having an azeotrope system ； relative volatility
The boiling point difference is very small； Having an azeotrope system ； relative volatility
The boiling point difference is very small； Having an azeotrope system ； relative volatility
The boiling point difference is very small； Having an azeotrope system ； relative volatility
Reply to 1# wsm1988: Azeotropic distillation and extractive distillation are primarily applied to systems with _azeotrope temperatures____ and _α values close to 1_. In both of these special distillation methods, a third component is added in order to alter the _α value__ of the original system.
Reply 1# wsm1988 Azeotropy, difficulty in separation, relative volatility
Azeotrope point, or relative volatility = 1; relative volatility
Systems with an azeotrope, relative volatility close to 1, relative volatility
Reply 1# wsm1988: It has an azeotropic composition, with boiling points that are close to each other, as well as a vapor phase fraction and relative volatility
Reply 1# wsm1988 Azeotropic distillation and extractive distillation are primarily applied to systems with _boiling points____ and freezing points____; in both of these special distillation methods, a third component is added in order to modify the ____component___ of the original system.
Reply to 1# wsm1988: Azeotropic distillation and extractive distillation are primarily used for systems with similar boiling points and vapor pressures; in both of these special distillation methods, a third component is added to alter the composition of the original system.
