Air Sensitive Vacuum Distillation

Air Sensitive Vacuum Distillation Interview questions

  1. When Air Sensitive Vacuum Distillation used?
  2. Why perkin triangle distillation apparatus used?

Many Chemical compounds are air sensitive and high in boiling point, and decompose at Higher temperature

A simple vacuum distillation system as exemplified above can be used, whereby the vacuum is replaced with an inert gas after the distillation is complete.

Air-Sensitive Vacuum Distillation

However, this is a less satisfactory system if one desires to collect fractions under a reduced pressure.

To do this a "pig" adaptor can be added to the end of the condenser, or for better results or for very air sensitive compounds a
