二甲基二硫 (DMDS) 是一种有机二烷基二硫化物。是我国典型城市生活垃圾填埋场工作面发现的有臭味化合物之一。DMDS 与单不饱和醋酸盐通过碳-碳双键加成形成加合物。这些加合物有助于确定长链单不饱和醋酸酯中双键的位置。用密度泛函理论 (DFT) 和高分辨电子能量损失谱 (HREELS) 研究了 DMDS 在 Au (111) 表面的吸附。 应用 二甲基二硫 (DMDS) 可用于烯烃的衍生化，以 MS 法测定双键的位置。也可用于结合 GC-MS 分析确定嗜冷弯曲杆菌中单不饱和脂肪酸的双键位置。 Dimethyl disulfide (DMDS) is an organic dialkyl disulfide. It is one of the odorous compounds found on the working face of typical municipal solid waste landfill in China. DMDS forms adducts with mono-unsaturated acetates by addition across carbon-carbon double bonds. These adducts are useful to locate the of double bonds in long-chain mono-unsaturated acetates. Adsorption of DMDS on Au(111) surface has been investigated by the density functional theory (DFT) within a generalized gradient approximation and experimental high-resolution electron energy loss spectroscopy (HREELS) techniques.Dimethyl disulfide (DMDS) may be used to derivatize alkenes for the determination of position of double bond by MS. It may also be used to determine the location of the double-bond position of monounsaturated fatty acids inCampylobacter cryaerophilaby combined GC-MS analysis.
