Study Notes

Vacuum Distillation

Distillation under reduced pressure
Used when undesirable to reach the normal boiling point of the distillate
Useful when the boiling point is high, or a heat-sensitive material is present
Vacuum pump reduces pressure, allowing the mixture to boil at a lower temperature
Can be potentially violent and unpredictable, leading to 'carryover' - liquid rather than vapour

Distillation - Applications

Manufacture of Whisky
Irish whiskey uses 3 pot stills
Brandy is distilled from fermented juice
Rum is distilled from fermented juice of sugar cane
Manufacture of spirits
Solvent recovery from oil after extraction
Essential oil extraction from leaves and seeds through steam distillation
