| titleOfInvention | A method for preparing high-purity ethyl aurinate by using Chinese torreya seed oil |
| abstract | The invention discloses a method for preparing high-purity ethyl aurinate by using Chinese torreya seed oil. The invention relates to a method for enriching auric acid in Chinese torreya seed oil combined with silver ion complexation coupled with high-speed countercurrent chromatography. First, use the difference in the distribution coefficients of different fatty acids in the two phases in high-speed countercurrent chromatography to achieve preliminary separation, and then combine the difference in the complexing ability of silver ions for double bonds to further improve the separation efficiency, remove saturated fatty acids and monounsaturated fatty acids in one step, and realize golden pine. Acid enrichment. In the present invention, by selecting a suitable solvent system and optimizing the type of silver salt and the silver ion/unsaturated double bond molar ratio, the efficient separation of torreya auric acid, saturated fatty acid and monounsaturated fatty acid is realized. The enrichment method has the advantages of simple equipment, high efficiency, high recovery rate of auromaric acid, and easy scale-up to industrial production. It is especially suitable for enrichment starting from low-concentration auromaric acid raw materials and realizing the preparation of high-concentration auromaric acid with a high recovery rate in one step. |
