| 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 IR spectra 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. |
