| abstract | A kind of take dihydroartemisinic acid as the method and apparatus that Artemisinin prepared by raw material, take dihydroartemisinic acid as the method that Artemisinin prepared by raw material, step is as follows: be dissolved in by dihydroartemisinic acid in organic solvent, add photosensitizers and acid catalyst, utilize the peroxide alcohol that light source makes dihydroartemisinic acid photoxidation be dihydroartemisinic acid, and acid catalysis carries out Hock cut-out, oxidative cyclization generates Artemisinin, whole reaction or only have photooxidation reaction to carry out in photoreactor.The present invention also comprises the photoreactor implemented described method and use.The inventive method temperature of reaction is low, and the yield of Artemisinin is high, and the utilization ratio of light source is high.Present device structure is simple, and low cost of manufacture, single batch of turnout is high. |
