| 摘 要： | 苯甲醛的光解与其在放置过程中的自氧化引发机理密切相关,因此确定光解过程的主要中间产物有重要意义。自氧化的全过程比较复杂,但单纯的光解本身显然相对简单一些。本文用自旋捕捉-ESR技术研究了苯甲醛及与其相类似的对溴苯甲醛在紫外和可见光作用下生成的活泼中间体,并讨论了在本文实验条件下的光解初级过程。

| Abstract: | Active intermediates produced in the photolysis of benzaldehyde and p-bromobenzaldehyde have been investigated by the spin trapping technique and ESR spectroscopy. The results show that the free radicals C6H5CO, p-BrC6H4CO, C6H5, and p-BrC6Hi are formed in the primary processes; and the free radicals C6H5CHOH and p-BrC6H4CHOH are formed in concentrated solution. |

| Keywords: | photolysis benzaldehyde ESR intermediate free radical |
