SELECTIVE OXIDATION OF HYDROGEN SULFIDE IN MOLTEN SULFUR

摘要

A method for inhibiting hydrogen sulfite evolution from moltensulfur is disclosed. The method involves adding a hypohalide to moltensulfur containing hydrogen sulfite. The hypohalide, such as hypochlorite,hyprobromite, and their sodium or calcium salts inhibit the evolution ofhydrogen sulfite from molten sulfur.
