Extraction of Clove oil from Cloves by steam distillation

Key steps + observations in the procedure for the extraction of clove oil from cloves by steam distillation:

• the apparatus for steam distillation is set up

• the steam generator or copper kettle provides steam

• the safety tube prevents a build of pressure formed by the steam

• steam tap prevents excess steam from entering the pear shaped flask

• liebig condenser condenses the emulsion: water in at the bottom out at the top

• a milky emulsion is collected, a mixture of clove oil and water

Draw a diagram of the steam distillation apparatus:

What are safety precautions are taken during this experiment?

• as steam is being used exercise care to avoid scalding

• euganol can burn the skin so gloves should be worn when handling the emulsion obtained 

What are some precautions taken during this experiment?

• ensure the bottom of the safety tube is placed below the water at all times, otherwise steam would escape rather than entering the pear shaped flask

Name the substance that is the main part of clove oil + draw its structure:

Eugenol (4-allyl-2-methoxy phenol)
