4,4'-methylenedianiline usage and synthesis

chemical properties	white to yellow or beige flakes or crystals
usage	4,4'-methylenedianiline be used as organic intermediates. mainly used for the synthesis of polyimide and as curing agent of epoxy resin.
general description	a tan flake or lump solid with a faint fishlike odor. may be toxic by inhalation or ingestion, and may be irritating to skin. insoluble in water.
air & water reactions	oxidizes slowly in air in a reaction catalyzed by light. somewhat hygroscopic. insoluble in water.
reactivity profile	4,4'-methylenedianiline polymerizes if heated above 257° f. incompatible with strong oxidizing agents. 4,4'-methylenedianiline is also incompatible with acids. catalyzes isocyanate-alcohol and epoxide reactions. flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
health hazard	toxic; inhalation, ingestion or skin contact with material may cause severe injury or death. contact with molten substance may cause severe burns to skin and eyes. avoid any skin contact. effects of contact or inhalation may be delayed. fire may produce irritating, corrosive and/or toxic gases. runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
fire hazard	combustible material: may burn but does not ignite readily. when heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. contact with metals may evolve flammable hydrogen gas. containers may explode when heated. runoff may pollute waterways. substance may be transported in a molten form.
