PROCESSES USEFUL IN THE MANUFACTURE OF CYCLODODECASULFUR
-
Paragraph 00280, (2020/09/30)
Methods for producing cyclododecasulfur are disclosed that include the steps of: reacting a bromide with molecular chlorine to obtain molecular bromine and a chloride; oxidizing the chloride in aqueous solution with removal of electrons to obtain molecular chlorine; reducing water with electrons to obtain hydrogen and a hydroxide; and reacting a metallasulfur derivative with the molecular bromine, to produce cyclododecasulfur and a metallabromide derivative.
Photolysis of Elemental Sulfur (S6, S7, S8, S10, S12) in Carbondisulfide Solution

, p. 682 - 690 (2007/10/02)
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
