Studies on the Mechanism of Sulfoxide in Extracting Carboxylic Acid

Abstract

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 R_f 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
