Distillation Flashcards
Vaporization
Liquid becomes vapor
Condensation
Gas becomes liquid
Simple distillation
Liquid mixture has 2 liquids with boiling pints less than 2 degrees c. Liquid must be soluble or miscible with each other
Vacuum distillation
When bp is more than 150 at 1atm. Vacuum reduces pressure inside system and brings down the boiling point of the liquid
Steam distillation
Tars,oils, natural products are distilled. These may be soluble or slightly soluble in water
Boiling chips are put in the distilling flask to avoid
Bumping
When should you add boiling chips
When liquid is cold
How big should the distilling flask be
Must be less than half full with the liquid you want to distill
Where should the bulb of the thermometer be located
Below the sidearm of the adapter
Water should runs through the condenser when the condenser is
Cold
Where should the water inlet be in the condenser?
The water inlet should be at the bottom and the outlet at the top
