WebThese mixtures have a boiling point greater than their respective constituents. They are also known as negative azeotropes or pressure minimum azeotropes. An example is hydrochloric acid at a concentration of 20.2% and 7.8% water (by mass), with a boiling point of 110℃. HCl has a boiling point of -84℃ and water has a boiling point of 100℃. Webof unknown proportions using fractional distillation. The two components of the mixture are able to be separated because toluene’s boiling point is 30˚C higher than cyclohexane’s boiling point. Cyclohexane should boil and distil before toluene. Even though their boiling points are different, it is difficult to isolate each component entirely.
