WebThe formation of the cyclohexene-water azeotrope is prevented by adding a third component to the mixture, such as cyclohexanol. This prevents the azeotrope from forming by breaking up the hydrogen bonds between the water and cyclohexene molecules. Another way to prevent the formation of the azeotrope is to use a fractional distillation … WebApr 12, 2024 · There are azeotropes water:toluene at 89 °C (0.49:0.51) and water:cyclohexane at 69 °C (30:70).
