Selective oxidation of hydrogen sulfide in molten sulfur |
摘要 |
A method for inhibiting hydrogen sulfite evolution from molten sulfur is disclosed. The method involves adding a hypohalide to molten sulfur containing hydrogen sulfite. The hypohalide, such as hypochlorite, hyprobromite, and their sodium or calcium salts inhibit the evolution of hydrogen sulfite from molten sulfur.
