| 11. | Such a system is called a double azeotrope, and will have two azeotropic compositions and boiling points.
|
| 12. | The only difference is that the compositions of the two phases are equal exactly at the azeotropic composition.
|
| 13. | Water removal by application of a vacuum or by azeotropic distillation is crucial to favor polycondensation over transesterification.
|
| 14. | Azeotropic mixtures on the other hand have constant properties at their azeotropic composition and behave like pure components.
|
| 15. | Azeotropic mixtures on the other hand have constant properties at their azeotropic composition and behave like pure components.
|
| 16. | It is characterized by an azeotrope temperature and an azeotropic composition, often expressed as a mole fraction.
|
| 17. | Boiling of any hydrochloric acid solution long enough will cause the solution left behind to approach the azeotropic ratio.
|
| 18. | That azeotropic composition can be affected by pressure suggests a means by which such a mixture can be separated.
|
| 19. | When both reactivity ratios are less than one, there is an azeotropic point in the Mayo-Lewis plot.
|
| 20. | Further enrichment is only possible by absorbing the remaining water using other means, such as hydrophilic chemicals or azeotropic distillation.
