Firstly, the synthetic methods of a flavonoid compound diosmin were firstly investigated through the continuous flow microchannel reactor with normal pressure and back pressure, respectively. The optimized continuous flow microchannel reactive conditions were thus obtained, and the conversive rate of the starting material hesperidin reached 98% and the yield of the product diosmin reached 90%. Then, the other flavonoid compounds included flavonoids, flavonols and isoflavones were successfully synthesized. The continuous flow microchannel reactive technology has not only achieved the conversive rate and yield equivalent to those of the traditional process, but also reduces the reaction time from 8~20 hours to 2~3 min. The reactive process became safer, faster and more efficient. The application of continuous flow microchannel reactive technology in pharmaceutical synthesis was further expanded. 查看全文查看/发表评论下载PDF阅读器 相关附件:附件1版权转让声明书附件1附件2版权转让声明书 -->
