Safety Statements: Violent explosion on contact with sodium disulfide. Reaction with potassium O,O-diphenylphosphorodithioates; o-alkyldithiocarbonate (xanthate) solutions; thiophenoxide solutions (e.g., sodium-2-chlorothiophenoxide; potassium thiophenoxide); various sulfides or derivatives (e.g., hydrogen sulfide; sodium hydrogen sulfide; sodium mono-, di- or poly-sulfides) forms highly explosive products. When heated to decomposition it emits toxic fumes of Cl− and NOx.
