An advantages of using vacuum distillation to distill a high boiling liquids includes:
1) boiling occurs at a lower temperature.
2) the boiling temperature is not affected much
3) requires expensive equipment
4) can prevent decomposition
Homework Answers
Vacuum distillation decreases the pressure due to which the boiling point of the liquid decreased . As we know Boling point decreases with decrease in pressure . Hence , Boling can occur at low temperature .
So it cause change in boiling temperature.
This is an expensive method and used for some specific liquids .
Yes this prevents product degradation or polymer formation ..
Hence , option a , c and d are correct .
Hope it helps you ,pls thumb's up

1. Explain how a fractionating column increases the separation of two liquids. 2. What is an azeotrope? Do you think the mixture used in the lab is an example of an azeotrope? Explain. 3. Explain how the boiling point of a liquid is affected by the addition of a non-volatile solute (hint: it is a colligative property). Is the temperature above such solution lower, higher or the same as the pure liquid? Explain why. 4. You were asked to record...

1. Both miscible distillations and steam distillations use boiling point differences to separate volatile liquids from mixtures. Using information in the powerpoint and the lab manual, compare the differences between steam distillation and miscible distillation in terms of: a. The temperature of distilling liquid throughout the course of the distillation. 2 pts b. The composition of the distillate throughout the course of distillation. 2 pts

Question 6 (10 pts) Steam distillation can be run more efficiently in some cases using super-heated steam at 1 atm pressure rather than boiling water. By increasing the temperature of the steam beyond the boiling point of water in a controlled fashion, the oil may still be protected from degradation while increasing its contribution to the vapor composition, making the process more efficient. At 150 °C, linalyl acetate exerts a vapor pressure of 93 torr. If a steam still were...

Assemble the glassware for fractional distillation according to the diagram and discussion above. Make certain that all joints are secure and that the apparatus is appropriately supported. Remember to allow for space below the distillation flask for the heating mantle and below the receiving flask for an ice bath. Pay extra attention to the positioning of the bulb of the thermometer as mentioned in the introduction. It is critical that the thermometer be positioned correctly for accurate temperature measurement. Using...
