Air Sensitive Vacuum Distillation Interview questions
- When Air Sensitive Vacuum Distillation used?
- 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.
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
