Sonochemistry: C3S2 originated by ultrasounding carbondisulfide
Quellhorst, Heike,Binnewies, Michael
, p. 259 - 261 (2008/10/09)
Pure carbondisulfide was treated with ultrasound of a frequency of 20 kHz. Consequently small amounts of C3S2, S6, S7, and S8 were obtained, which could be seperated gas-chromatographically and detected by mass spectroscopy. The yields were approximately proportional to the period of influence. Johann Ambrosius Barth 1996.
Photolysis of Elemental Sulfur (S6, S7, S8, S10, S12) in Carbondisulfide Solution

The photochemical decomposition of pure carbondisulfide as well as of solutions of pure S6, S7, S8, S10 and S12, respectively, in CS2 at 15 deg C on irradiation by a high-pressure mercury lamp (200-600 nm) has benn studied by quantitative HPLC analysis of the soluble products.In all cases mixtures of sulfur homocycles Sn (n = 5, 6, ...) are formed with S8, S7 and S6 being the dominating species, but traces of S5, S9, S10 and S12 have also been observed in most cases.S5 has been identified for the first time; it is formed in particular in the photolysis of S7 in CS2.All irradiated sulfur solutions reach more or less the same photostationry equilibrium, but the decomposition of CS2 increases linearly with time and its effects are superimposed on the Sn interconversion reactions. - Key words: Elemental Sulfur, Photolysis, HPLC, Carbondisulfide, Sulfur Homocycles
