Vacuum Distillation

History of Distillation Distillation was

developed into its modern form with the invention of the alembic by Islamic alchemist Jabir ibn Hayyan in around 800 AD.

Instruments Of Alchemists For Distillation

Vacuum DistillationVacuum distillation is a technique that uses a vacuum to extract analytes from a sample. A condensingcolumn is used inthe technique to condense water that may also be present in the sample. A cryogenically cooled trap (cryotrap) is used to condense the compounds of interest.

The Modern Laboratory Distillation Plant

Distillation in Use1. Separating Crude Oil into more Fractions

(for specific uses such as transport, power generation and heating)

• 2.Distillation of Water (separating salt from sea water)

• 3. Distillation of Air

1. Oxygen (for medical application);

2. Helium (for party balloons).

Applications of distillation Laboratory scale; Industrial

distillation; Distillation of herbs

for perfumery and medicinals (herbal distillate);

Food processing.
