Solubility of Lithium Octasulfide in Sulfolane Solutions of Lithium Perchlorate

The solubility of long-chain lithium polysulfides (nominally Li 2 S 8 ) in sulfolane and sulfolane solutions of lithium perchlorate has been studied. It was found that the solubility of sulfur in the species of lithium octasulfide is significantly, by one to two orders of magnitude, higher than the...

Description
Summary:The solubility of long-chain lithium polysulfides (nominally Li 2 S 8 ) in sulfolane and sulfolane solutions of lithium perchlorate has been studied. It was found that the solubility of sulfur in the species of lithium octasulfide is significantly, by one to two orders of magnitude, higher than the solubility of elemental sulfur. The rate of Li 2 S 8 formation and its solubility decreases, as the concentration of LiClO 4 increases. The absorption spectra of Li 2 S 8 are similar to the absorption spectra of elemental sulfur except for the position of the long-wavelength absorption bands, which have a significant bathochromic shift.
