Abstract: | Molecular Composition of Liquid Sulfur. Part 3: Quantitative Analysis in the Temperature Region 115–350°C Relative concentrations of S6, S7, S8, Sx (x > 8) and Sμ (insoluble sulfur) in equilibrium melts of elemental sulfur have been determined from i. r. and Raman spectra. At the freezing point (115°C) the melt consists of 0.6% S6, 2.8% S7, 1.5% Sx, and 95.1% S8. – The solubility of S7 in CS2 has been determined at −77 to −26°C; the solubilities of both S7 and S8 in CS2 are considerably enhanced by the presence of Sx. The thermal decomposition of S8 and Sμ formation from S6, S7, and Sx has been investigated. |
