Refining method: The content of about 40% of the cut was added to cadmium nitrate, collecting the resulting precipitate. With a mixture of cadmium nitrate washing, steam distillation after treatment with 30% sodium hydroxide solution, the oil will be free from steam distillation to obtain pure. Yield 73.0% ~ 74.9%, melting point 23.7 ~ 25 ℃. In addition, 5A molecular sieves or anhydrous sodium sulfate can also be dried and then vacuum distillation method refined.
