The following list only include the common oil names without important details. 000g?100%=21. The first day the clove oil was removed from the ground cloves into an aqueous solution then removed from the water using DCM. If you need this or any other sample, we can send it to you via email. The results were obtained (Figure 1) and analyzed to find the major constituent. In health remedies, they find use as treatment oils, pastes and salves for minor aches, pains, congestion and coughing. The same is true in any industry. Eugenol will be extracted from the distillate with dichloromethane and analyzed using the Thermo Scientific picoSpin 45 or Thermo Scientific picoSpin 80 NMR spectrometers. 4%. Essential oils also have a long history of use in traditional medicines. Isolation of Clove Oil: The steam distillation apparatus was assembled and then the water in the distilling column was turned on. In FTIR spectroscopy (see Figure 2), the spectrum of the additives and base oil can be subtracted from the spectrum of the used oil sample to achieve a differential spectrum that only shows variations in the oil.
