Rp 05- Distillation Of A Reaction Product

Question 1

What is distillation?

Answer 1

Where a liquid is heated to a vapour which is cooled by a condenser, causing the gas to condense into a liquid and drip into a separate flask.
The species separate due to relative volatilities and boiling points.

Question 2

What equipment is used for distillation?

Answer 2

• semi-micro distillation apparatus
• quick-fit apparatus

Question 3

Oxidising agents are often used in distillation. What is an oxidising agent?

Answer 3

• oxidising agents oxidise chemicals by receiving electrons from them.
• oxidising agents are in turn reduced

Question 4

Why are anti-bumping granules used in distillation?

Answer 4

To allow smooth-boiling preventing bubbles caused by vapour to cause upwards splashing in the flask.

Question 5

How do you isolate a liquid product?

Answer 5

• use a separating funnel to isolate the organic layer from the aqueous layer.
• shake the flask, allow layers to separate
• then open the tap and run off one layer into a separate container
