Modified methods for the synthesis of various sulfoxides with isomeric octyl groups, i.e.dioetyl sulfoxides, bis (octylsulfenyl) methane and bis (octylsulfenyl) ethane are described. Theextraction behaviours of these sulfoxides for lanthanides from nitric acid system are studiedand discussed on the basis of their chemical structures. The composition and the structureof the extracted species are deduced by method of continuous variation as well as by ele-mental and thermo-gravimetric analysis. As shown by infrared spectroseopic studies thesulfenyl oxygen acts as coordinating atom and the NO_3 serves as bidentate.
