摘要
研究了在超声波辐射条件下,市售二氧化锰在5%HCl溶液中氧化吡哆醇为吡哆醛的反应.结果表明,商品二氧化锰可在温和的条件下被超声波辐射活化,在氧化反应中具有良好的氧化性能.与非超声辐射条件下相比,二氧化锰氧化吡哆醇的氧化速率大大提高,反应时间由5h减至30min.
The oxidation of pyridoxol to pyridoxal by the commercial MnO_2 under ultrasonic radiation is investigated in diluted HCl. The result shows that the MnO_2 can be activated by ultrasonic radiation under the moderation condition and it has fine oxidation ability. Compared with that under the common condition, the reaction time for oxidation of pyridoxol to pyridoxal under ultrasonic radiation decreases from 5 h to 30 min.
