Fractional Distillation Flashcards
1
Q
Describe the process of fractional distillation
A
- the oil is heated until most of it is gas, these gases enter a fractionating column
- longer hydrocarbons have high boiling points, so condense at the bottom
- shorter hydrocarbons have low boiling points,
So turn into liquid much later on at the top
2
Q
What stops the liquid running back down into the next fraction
A
Bubble caps
3
Q
What decreases as you go up the column
A
- viscosity decreases
- boiling point decreases
