Organic Chemsitry: Distillation Lab

1. Why does a solution containing a non-volatile component have a different temperature in the still-pot than at the still-head?

2.Why does a solution containing two volatile components have the same temperature in the still-pot and at the still head?

3. For a 24-mL sample of a two component mixture where A boils at 75 oC and B boils at 90 oC, what is true about the following four fractions (6 mL each) collected by simple distillation

a. Which component has a higher mole fraction in the first fraction?

b. Compare ratios of A and B in collections 2 and 3.

c. What is the major component left in the still-pot

14. What are the advantages and disadvantages of collecting 4 fractions by distillation versus 20 fractions?

15.Why does insulating the fractionating column improve the process of this type of distillation?
