| titleOfInvention | Method for extracting cedrene and cedrene from fir oil |
| abstract | A method for extracting cedrene and cedryl alcohol from Chinese fir oil, comprising the steps of: first steaming out the light components in the Chinese fir oil by distillation, so that the content of cedryl alcohol in the heavy component Chinese fir oil in the tower kettle is ≥ 60%, and then Natural cooling and crystallization, and then crushing and high-speed centrifugation to obtain crude cedarwood alcohol. The crude cedaryl alcohol is melted and recrystallized, and then crushed and then centrifuged at a high speed to remove the impurities wrapped in the cedaryl alcohol crystallization process to obtain the cedaryl alcohol product. After mixing the centrate obtained by twice centrifugation and the light component obtained by distillation, it is added to a packed tower, and the product cedrene is obtained by vacuum fractionation. The cedrene content of the product is ≥90%, and the cedrene content is ≥85%. |
