POLYSULFIDE SOLUTIONS AND HYDROXYALKYL AMINIUM IONS FOR STABILIZING ELEMENTAL SULFUR |
摘要 |
Hydroxalkylaminium polysulfides are used to provide cold stability to ammonium polysulfide solutions. Hydroxyalkylaminium sulfides or polysulfides also are used to solubilize unwanted sulfur. Preferred aminium ions are monohydroxyalkylaminium ions, preferably monoethanolaminium ions. When added to an aqueous stream comprising free cyanide ions (including HCN), the polysulfide solution reduces corrosion of metal equipment contacted by the stream by converting the free cyanide ions into thiocyanate ions.
