| titleOfInvention | A kind of synthetic method of high-purity astaxanthin |
| abstract | The invention discloses a kind of synthetic method of high-purity astaxanthin, comprise the following steps：Dehydrogenation astaxanthin is dissolved in organic solvent, then adds water, zinc powder and phase transfer catalyst, then glacial acetic acid is added dropwise and carries out reduction reaction, described astaxanthin is obtained by post processing after the completion of reaction.The synthetic method reduces side reaction, improves the yield and purity of reaction, and effectively reduce the dosage of glacial acetic acid by adding a certain amount of water and phase transfer catalyst in reaction system. |
