  • 可作冠军国际betcmp官方网站溶剂、反应介质及冠军国际betcmp官方网站合成中间体。用途极广。本品具有很高的选择性抽提能力,用作丙烯酸树脂及聚砜树酯的聚合和缩合溶剂、聚丙烯腈及乙酸纤维的聚合抽丝溶剂、烷烃与芳烃分离的抽提溶剂、用于芳烃、丁二烯抽提,腈纶纺丝、塑料溶剂及冠军国际betcmp官方网站合成染料、制药等工业的反应介质。在医药方面,二甲基亚砜有消炎止痛作用,对皮肤有强渗透力,因而可溶解某些药物,使这类药物向人体渗透从而达到治疗目的。利用二甲基亚砜的这种载体特性,也可作为农药的添加剂。在某些农药中添加少量二甲基亚砜,有助于农药向植物内渗透,以提高药效。二甲基亚砜还可作为合成纤维的染色溶剂、去染剂、染色载体,也可作为回收乙炔、二氧化硫的吸收剂,合成纤维改性剂,防冻剂以及电容介质、刹车油、稀有金属提取剂等。
  • Tosylates or activated halides can be oxidized with DMSO to aldehydes and ketones (Kornblum oxidation). ɑ-Bromo ketones are oxidized at room temperature to ɑ-keto aldehydes: J. Am .Chem. Soc., 79, 6562 (1957). Benzylic halides, on heating in the presence of NaHCO3, give benzaldehydes: J. Am. Chem. Soc., 114, 6227 (1992). Under similar conditions at 150oC, primary alkyl iodides: J. Chem. Soc., 520 (1964), and alkyl chlorides and bromides in the presence of NaI: Synth. Commun., 16, 1343 (1986), are oxidized to aldehydes. Unactivated bromides have also been oxidized to aldehydes in the presence of Ag salts: Tetrahedron Lett., 917 (1974). For oxidation of benzyl alcohols to benzaldehydes, catalyzed by HBr, see: Synlett, 2041 (2002). DMSO is more often used in combination with a variety of activating agents for selective oxidation of primary and secondary alcohols to carbonyl compounds under very mild conditions. For examples, see: Oxalyl­ chloride, A18012, or Trifluoroacetic anhydride, A13614 (Swern oxidation), Acetic anhydride, L04295 (Albright-Goldman), N,N'-Dicyclohexyl­carbodiimide, A10973 (Pfitzner-Moffatt), Sulfur trioxide-pyridine complex, A12202 (Parikh-Doering), Triphosgene, A14932 and Phenyl­ phosphorodichloridate, A10479.
