Notice that the boiling point for any mixture is between the boiling points of the pure components. The curve connecting the points can be used to determine the boiling point of any mixture of these two components. For example, an ethanol-butanol mixture that is 0.50 mole fraction in ethanol (i.e. 50% ethanol 50% butanol) will boil at 91.3 C.
