Steam distillation can be carried out in two ways: the direct method and the live steam method3 in the direct method, steam is generated by boiling a mixture of the source of the compound of interest and water. The boiling point of eugenol, an oil found in cloves, is 248 °c, but it can be isolated at a lower temperature by performing a co-distillation with water, this process is also know as a steam distillation. In steam distillation, the distilling pot is infused with steam, which carries the oil’s vapor into the distilling head and then into the condenser, where the oil and water co-condense as an alternative, steam is generated in situ in the distilling pot.
