4,4'-thiodianiline usage and synthesis |
chemical properties | brown-purple powder |
general description | needles or brown powder. |
air & water reactions | insoluble in water. |
reactivity profile | 4,4'-thiodianiline is incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. may generate heat with these materials and hydrogen gas or hydrogen sulfide gas. may liberate hydrogen sulfide if heated to decomposition or mixed with an acid. also incompatible with peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. |
health hazard | acute/chronic hazards: when heated to decomposition 4,4'-thiodianiline emits very toxic fumes. |
fire hazard | flash point data for 4,4'-thiodianiline are not available, however 4,4'-thiodianiline is probably combustible. |
