Chemical Separation: Vacuum Distillation Explained

Click For Summary
SUMMARY

Vacuum distillation is a distillation process conducted under reduced pressure, allowing for lower boiling temperatures and minimizing the decomposition of heat-sensitive compounds. This method is particularly useful for liquids with high atmospheric boiling points or those that chemically change at temperatures close to their boiling points. The principle of vacuum distillation is that boiling occurs when the vapor pressure of a liquid exceeds the ambient pressure, facilitating the separation of components in a mixture.

PREREQUISITES
  • Understanding of distillation principles
  • Familiarity with vapor pressure concepts
  • Knowledge of chemical properties of liquids
  • Experience with laboratory-scale techniques
NEXT STEPS
  • Research the principles of vapor pressure and boiling point relationships
  • Learn about laboratory-scale vacuum distillation techniques
  • Explore applications of vacuum distillation in chemical engineering
  • Study the differences between vacuum distillation and traditional distillation methods
USEFUL FOR

Chemists, chemical engineers, laboratory technicians, and anyone involved in the separation of heat-sensitive compounds in a laboratory setting.

I don't get what is vacuum distillation anyone can help me with this
 
Chemistry news on Phys.org
Reduced pressure, lower temperatures, less decomposition?

Hi, it is a distillation in vacuum ambient, it reduce the pressure. From Wiki:

''Laboratory-scale vacuum distillation is used when liquids to be distilled have high atmospheric boiling points or chemically change at temperatures near their atmospheric boiling points''

''This distillation method works on the principle that boiling occurs when the vapor pressure of a liquid exceeds the ambient pressure''

Please don't list the final answer to the people who even didn't bothered to read the wiki article.

This is not the final answer, I tell him the basic principle and a source of information ... sorry Mentor @Borek but the question was so general, he doesn't asked a precise dubt on vacuum distillation he asked what is the vacuum distillation ...
 
thank you guy's
