High vacuum distillation

WebThe vacuum distillation method is also used to obtain high-purity samples of compounds that decompose at high temperatures. Short Path Distillation and Other Classifications In short path distillation, the separated compounds are condensed immediately, without traveling to the condenser. WebApr 12, 2024 · Steam distillation is a process used to extract essential oils from plants. It involves passing steam through a plant material to extract the oils. The steam carries the oils with it, and as it cools, the oils condense and separate from the water. Vacuum Distillation. Vacuum distillation is used to distil liquids that have high boiling points.

http://www.chem.ucla.edu/~bacher/Specialtopics/vacuum%20distillation.html WebThe vacuum lowers the pressure, making it easier to reach higher boiling points. Boiling occurs when the liquid's vapor pressure is equal to the pressure of the gas above it, so lowering the gas pressure makes it possible to boil liquids at a lower temperature.
