  • PROCESSES USEFUL IN THE MANUFACTURE OF CYCLODODECASULFUR
    Publication number: 20220169506
    Abstract: Methods for producing cyclododecasulfur are disclosed, that include the steps of: oxidizing a bromide in aqueous solution to produce a mixture of molecular bromine, tribromide, and bromide; reducing water to produce hydrogen and a hydroxide; and reacting a metallasulfur derivative with the molecular bromine, to produce cyclododecasulfur and a metallabromide derivative.
    Type: Application
    Filed: March 5, 2020
    Publication date: June 2, 2022
    Applicant: EASTMAN CHEMICAL COMPANY
    Inventors: SCOTT DONALD BARNICKI, ROBERT THOMAS HEMBRE, SUMIT CHAKRABORTY, MICHAEL RICHARD LANINGHAM, VICKIE HAGOOD OSBORNE, LESLIE SHARON DEPEW, ANNETTE ELIZABETH STEVENS, JOHN DEREK WOOLLINS, GUOXIONG HUA
  • PROCESSES USEFUL IN THE MANUFACTURE OF CYCLODODECASULFUR
    Publication number: 20220169505
    Abstract: Methods for producing cyclododecasulfur are disclosed that include the steps of: reacting a metallasulfur derivative with a molecular halogen to produce cyclododecasulfur and a metallahalide derivative; and reacting the metallahalide derivative with a sulfide or polysulfide to produce the metallasulfur derivative and a halide.

  • PROCESSES USEFUL IN THE MANUFACTURE OF CYCLODODECASULFUR
    Publication number: 20220162068
    Abstract: 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.

  • PROCESSES USEFUL IN THE MANUFACTURE OF CYCLODODECASULFUR
    Publication number: 20220162761
    Abstract: Method for producing molecular halogen are disclosed, that include the steps of: oxidizing a halide to produce a mixture comprising one or more of a molecular halogen, a trihalide, and a halide; reducing a polysulfide comprising a higher rank polysulfide dianion to produce a lower rank polysulfide dianion; and recovering molecular halogen from the mixture comprising one or more of a molecular halogen, a trihalide, and a halide.
