| 摘 要： | 本文对二甲基硫醚(DMS)在有氧、无氧及有H2O2存在的情况下紫外光辐照。然后在20m长光程池中藉富里叶红外光谱仪测定光解产物的吸收光谱。实验表明在无氧的情况下DMS的C─S键断裂,并生成CH3SSCH3及C2H6,在有氧存在下生成HCHO及CH3SO3H,在有H2O2存在下生成CH3SSCH3.本文讨论了光解的可能机理,合理地解释光解产物的生成。

| Abstract: | The dimethyl sulfide(DMS) was irradiated by UV in the absence or presence of O2 and H2O2.The products of photolysis were detected by a Fourier Transform Infrared Spectroscopy equipped with a 20m long path cell. The results indicate that the C─S bond of DMS could be broken in the absence of O2. As a result, CH3SSCH3 and CH3CH3 compounds were formed. In the case of presence of O2 in the system,CH2O and CH3SOH could be formed. If H2O2 presents in the system, the products of photolysis of DMS would be CH3SO3H and CH3SSCH3. The mechanism of photolysis of DMS has been discussed. According to this mechanism, the formation of products can be explained. |
