自1866年Saytzeff首先报告二甲亚砜(简称DMSO)以来,很长时期对它的性质及应用了解极少。直至二十世纪五十年代,才逐渐用作有机及无机化合物的溶剂。近来在科学研究,工艺生产许多领域中也得到较广泛的应用,很引人注意。如测定红外光谱及NMR时用作溶剂,纸层析、气层析以及分离提取一些有机化合物(如多环烃、多卤烃、苯二甲酸酯、乙炔、二氧化硫等)也很有用。在DMSO中测定分子量
Since the first report of dimethylsulfoxide (DMSO) in 1866, Saytzeff has known very little about its nature and application for a long time. Until the 1950s, it was gradually used as a solvent for organic and inorganic compounds. Recently, it has attracted a great deal of attention in many fields such as scientific research and process production. It is also useful to determine some of the organic compounds (such as polycyclic hydrocarbons, polyhalocarbons, phthalates, acetylene, sulfur dioxide, etc.) for determination of infrared spectroscopy and NMR as solvents, paper chromatography, gas chromatography, and separation. The molecular weight is determined in DMSO
