The interactions of methyl, tetramethylene, and propyl sulfoxides and propyl sulfone during sorption onto four dewaxed, acid-form peats have been studied by means of swelling measurements. The results for sulfoxides are displayed as heteromolecular sorption isotherms, which plot amount sorbed versus S=O group activity (molar density ratio relative to methyl sulfoxide). The present swelling data are compared to previous data for a homologous series of alcohols. Propyl sulfone apparently reacted with the peats during the sorption process, and one peat (Canadian) exhibited a dramatic 26% shrinkage in volume when exposed to this reagent for 8 weeks. Pyrolysis-GC-MS study of sulfone-doped Canadian peat found that propyl sulfide was the predominant pyrolysis product, although traces of propyl sulfoxide and sulfur dioxide were also found.
