Dear Sir. Concerning your issue about the solubility of elementary sulfur in DMSO as a function of temperature . The solubility of S in DMSO with 1 M of different salts was determined. First, in a pure organic solvent, the solubility of S is dependent on the polarity and the Lewis basicity of the solvent. The solubility of a non-polar S molecule should be higher in a non-polar solvent than that in a polar solvent, for example, the solubility of S in hexane is an order of magnitude higher than that in acetonitrile. I think the following below links may help you in your analysis:
