Abstract
Solvent mixtures for dissolving elemental sulfur, methods of utilizing the solvent mixtures, and methods of forming the solvent mixtures. The solvent mixtures include an elemental sulfur solvent fraction and an odorant fraction. The elemental sulfur solvent fraction includes an elemental sulfur solvent that has a solvent odor and a solvent sulfur solubility of at least 10 weight percent (wt %). The odorant fraction includes at least one odorant that has an odorant odor that differs from the solvent odor. The solvent mixture includes at least 20 wt % and at most 80 wt % of both the elemental sulfur solvent fraction and the odorant fraction. The presence of the odorant fraction, within the solvent mixture, decreases an intensity of the mixture odor relative to the solvent odor and/or decreases an offensiveness of the mixture odor relative to the solvent odor.
