Green chemistry is made up of many principles that help keep the environment the safe from harmful chemicals. One of those principles have to do with using safer solvents. Solvents can be used for a variety of processes including separating organic compounds from a polar mixture. This research examined the extraction process using green and non-green solvents from clove oil. Cloves contain eugenol, an aromatic compound with numbing properties often used to treat tooth pain. The green solvent used in the extraction was a ratio of 3:1 ethyl acetate ethanol and the non-green solvent was dichloromethane. It was found that the non-green solvent performed slightly better than the green variant. The green solvent extracted 8% less oil when compared to non-green solvent.
