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R_f值发现,亚砜萃取有机酸的机理中空腔效应起着重要作用。
The logarithmic structure of the tartrate sour sulfoxide complex was determined by the double logarithm method and was confirmed by infrared spectroscopy to be hydrogen-bonded to the sulfoxide. The field ion desorption mass spectrometry can directly observe the molecular ions and quasi-molecular ions of the organic acid sulfoxide extraction complex. Comparing the Rf values of various organic acid paper chromatography, it is found that the cavity effect plays an important role in the mechanism of the organic acid extraction by the sulfoxide .
