摘要: 用双对数法测出酒石酸石油亚砜萃合物的在观结构,并用红外光谱证明酸与亚砜以氢键相连。利用场解吸质谱可直接观察到有机酸亚砜萃合物的分子离子和准分子离子,比较多种有机酸纸层析的Rf值发现,亚砜萃取有机酸的机理中空腔效应起着重要作用。

Abstract: By using double logarithm method,the macroscopic structure of extraction complex of diesel oil sulfoxide and tartaric acid was identified.It is proved by IRspectra that sulfoxide and tartaric acid form extraction complex by way of hydrogen bond.The molecular ions of the extraction complex were observed directly in field desorption mass spectrometry and the structure of extraction complex exists in more than one form.Comparing the Rf value of paper chromatography of various carboxylic acid,it is discovered that the hollow effect plays an important role on the mechanism of sulfoxide in extracting carboxylic acid.

Key words: Hollow effect, Extraction complex, Field desorption mass spectrometry, Sulfoxide, Carboxylic acid
