  • Extraction of Eugenol from Cloves Oil
    obtain the essential oil from cloves by steam distillation. You will then separate a component (acetyleugenol) from the oil by liquid-liquid extraction. Finally, you will isolate the acetyleugenol by using a rotovap for reduced pressure distillation, which will remove the organic solvent (dichloromethane)...
