本工作以高分子化的孟加拉玫瑰为单线态氧敏化剂,对二乙基硫醚光氧化为二乙基亚砜的反应进行了研究。通过稳态处理,得到了光氧化反应的动力学公式。实验证明,存在着与上述公式相符的下列关系式: R_(Ox)=K[R_2S]~0[O_2]~(0.42)[I] In this work, macromolecularized Bengal rose as a singlet oxygen sensitizer was used to study the photooxidation of diethyl sulfide to diethyl sulfoxide. Through the steady state processing, the kinetic formula of photooxidation reaction was obtained. Experiments show that there exists the following relationship which is consistent with the above formula: R_ (Ox) = K [R_2S] ~ 0 [O_2] ~ (0.42) [I]
