Question:

6. a. A mixture of 60 mol % n-propy!cyclohexane and 40 mol % n-propylbenzene is distilled through a simple distillation apparatus; assume that no fractionation occurs during the distillation. The boiling temperature is found to be 157。C (760 torr) as the first small amount of distillate is collected. The standard vapor pressures of n-propylcyclohexane and n-propylbenzene are known to be 769 torr and 725 torr, respectively, at 1573 °C Calculate the percentage of cach of the two components in the first few drops of distillate. A mixture of 50 mol % benzene and 50 mol % toluene is distilled under exactly the same conditions as in Part a. Using Figure 5.1, determine the distillation temperature and the percentage composition of the first few drops of distillate. b. c. The normal boiling points of n-propylcyclohexane and n-propylbenzene are 156 °C and 159 °C, respectively. Compare the distillation results in Parts a and b. Which of the two mixtures would require the more efficient fractional distillation column for separation of the components? Why?
