4,4'-Methylenedianiline Usage And Synthesis
Chemical Propertieswhite to yellow or beige flakes or crystals
Chemical Properties4,4’-Diaminodiphenylmethane is a pale yel- low crystalline solid (turns light brown on contact with air) with a faint amine-like odor.
Uses4,4'-methylenedianiline be used as organic intermediates. Mainly used for the synthesis of polyimide and as curing agent of epoxy resin.
UsesAs chemical intermediate in production of isocyanates and polyisocyantes for preparation of polyurethane foams, Spandex fibers; as curing agent for epoxy resins and urethane elastomers; in production of polyamides; in the determination of tungsten and sulfates; in preparation of azo dyes; as corrosion inhibitor.
DefinitionChEBI: An aromatic amine that is diphenylmethane substituted at the 4-position of each benzene ring by an amino group.
General DescriptionA 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 ReactionsOxidizes slowly in air in a reaction catalyzed by light. Somewhat hygroscopic. Insoluble in water.
Reactivity Profile4,4'-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 HazardTOXIC; 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 HazardCombustible 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.
Safety ProfileConfirmed carcinogen with experimental tumorigenic data. Human poison by ingestion. Poison by subcutaneous and intraperitoneal routes. Human systemic effects by ingestion: rigidity, jaundice, other liver changes. An eye irritant. Mutation data reported. It is not rapidly absorbed through the skin. Combustible when exposed to heat or flame. When heated to decomposition it emits highly toxic fumes of aniline and NOx.
Potential ExposureUsed as an intermediate and as a curing agent. Approximately 99% of the DDM produced is con- sumed in its crude form (occasionally containing not more than 50% DDM and ply-DDM) at its production site by reac- tion with phosgene in the preparation of isocyanates and poly- isocyanates. These isocyanates and polyisocyanates are employed in the manufacture of rigid polyurethane foams which find application as thermal insulation. Polyisocyanates are also used in the preparation of the semiflexible polyure- thane foams used for automotive safety cushioning. DDM is also used as: an epoxy hardening agent; a raw material in the production of polyurethane elastomers; in the rubber industry as a curative for Neoprene and as an antifrosting agent (anti- oxidant) in footwear; a raw material in the production of Quana nylon; and a raw material in the preparation of poly (amide-imide) resins (used in magnet wire enamels).
Carcinogenicity4,4′-Methylenedianiline and its dihydrochloride salt are reasonably anticipated to be human carcinogens based on sufficient evidence of carcinogenicity from studies in experimental animals.
ShippingUN2651 4,40 -Diaminodiphenyl methane, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Purification MethodsCrystallise the amine from water, 95% EtOH or *benzene. [Beilstein 13 IV 390.]
IncompatibilitiesDust forms and explosive mixture with air. May polymerize in temperatures .125℃ . A weak base. Incompatible with strong oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong acids. Flammable gas- eous hydrogen may be generated in combination with strong reducing agents, such as hydrides .
Waste DisposalControlled incineration (oxides of nitrogen are removed from the effluent gas by scrubbers and/or thermal devices).
