前文报道了在金属卟啉-次氯酸钠模拟体系中氧化苯甲醛时,金属卟啉结构与其催化性能的关系,结果表明:四(2.6-二氯)苯基卟啉合锰是稳定性能最好及活性较高的催化剂。本文进一步报道各种因素对反应的影响,并在此基础上提出了由芳醛合成相应羧酸的新方法。

The catalytic oxidation of aromatic aldehydes by sodium hypochlorite- manganeseporphyrin complex system has been studied. The effects of some factors such as solvent, reaction temperature, phase transfer catalyst, concentration of manganeseporphyrin, single oxygen donor and the addition method of sodium hypochlorite to the system mentioned above on the oxidation reaction were investigated. This work provides a new method for preparing aromatic acids from their corresponding aldehydes in good yields.
