Abstract
The R F values of representative dialkyl, methyl alkyl, ethyl alkyl, and phenyl alkyl sulphoxides were determined on aluminium oxide for various eluants. It was found that benzene-pyridine (20:1) and dioxane were most suitable for adsorption chromatography, while for the separation of long-chain compounds by partition chromatography (stationary phase dinonyl phthalate) a mixture of methanol-water-pyridine (5:1:1) could best be used. By using a two-dimensional procedure, the identification of the components of a complex mixture of sulphoxides is largely possible.
