What is the purpose of using Hickman still instead of a conventional distillation apparatus in this synthetic experiment? Explain the advantages.

Expert Solution

Solution:

The purpose of using Hickman still instead of a conventional distillation apparatus is,

Hickman distillation still is used in distillation to carry short path microscale distillation. Hickman distillation apparatus is a micro-scale purification apparatus that is used to distill small amounts of materials. This is similar to a simple distillation and only one fraction is usually collected. The purity is again related to the difference in boiling points, and fractionating columns can be employed to increase separation and purity.

Advantages:

1. It is short path distillation in which distillation is carried out in short path and in quick time.

2. Loss of material during distillation is less. Due to short path distillation material loss is very low.

3. No need of bulk quantity solution, even in small quantity distillation will carried out.

4. More advantage in research and development field.

5. Collection of fractions is easiest.

2. A simple distillation apparatus has a round bottom flask with a volume of 100 mL and a distillation head with a vertical volume of 12.0 mL. At the end of a distillation, vapor would fill this volume but could not be moved to the condenser. If no liquid remains, use the ideal gas law and a b.p. of 100°C at 760 mm Hg to calculate the volume of liquid in mL (d = 0.900 g/mL and m.w. = 200.0...

Flash distillation A still is charged with 1000 moles of a 58.5 mole % methanol(M) and 41.5 mole % 1-propanol mixture. This mixture is distilled until 200 moles remain in the still and the cumulative distillate collected. You may assume that the relative volatility is 3.6 and it remains the same during the distillation process. a) What are the feed and distillate flow rates during the process? b) For the flas option, determine the equilibrium distillate and bottoms compositions c)...

The stone is a unit of mass that is still sometimes used in England, instead of pounds or kilograms, as an expression of human weight. A stone is equal to 14 pounds and about 6.35 kilograms. Take a position (for or against) on using the standard of kilograms as an international measure of human weight. What are the advantages to the unified system of using the kilogram for weight? What are the disadvantages? Who might be resistant to adopting the...

What purpose does the electoral college serve? Does it still serve as a protection for small states, or is used as a way to control the political process with less than a majority of the votes? Defend your position with facts. As we wrap up your examination of the political process, consider whether we should be limited to just two parties or would we be better served with several different parties?
