Flammability characteristics:Flammable; burning produces toxic nitrogen oxides and sulfur oxide fumes
Air and Water Reactions:Dust explosion: 0.140 oz/ft3. Insoluble in water. This chemical is moisture sensitive. (NTP, 1992).
Reactive Group:Amines, Phosphines, and Pyridines
Reactivity Profile:An organosulfide and an amine. Organosulfides are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
