11. Water and ethanol form an azeotrope . 12. The ternary mixture of chloroform, methanol and acetone has three binary azeotropes and one ternary azeotrope . 13. Such a system is called a double azeotrope , and will have two azeotropic compositions and boiling points. 14. A new process was introduced, in which Xylene was added to produce an azeotrope with the water. 15. It is characterized by an azeotrope temperature and an azeotropic composition, often expressed as a mole fraction. 16. How much would methanol depress the boiling point of the mixture, if they form a positive azeotrope ? 17. So in this case too, the distillate moves away from the azeotrope and the residue moves toward it. 18. The meeting point is called an "'azeotrope "'for that particular pair of substances. 19. :You can't use evaporation to concentrate hydrogen peroxide above the point where it becomes an azeotrope . 20. The point, A, shown here is a boiling point with a composition chosen very near to the azeotrope .
