摘要: 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: ROx=K[R2S]0[O2]0.42[I]

Abstract: The photooxidation of diethyl sulfide to diethyl sulfoxide was studied in methanol solution by using polymeric Hose Bengal as singlet oxygen sensitizer.Experimental results have led to the following relation for the reaction rate of pho-tooxidation which is in agreement with the kinetic equation obtained under photostation-ary conditions:ROx=K[R2S]0[O2]0.42[I]
