4,4'-Oxydianiline Usage And Synthesis
  • UsesBis(p-aminophenyl) Ether is a reagent used in the preparation of polyimide-silica composite membranes for gas separation techniques. In addition, it is used in the synthesis of polymer films for electrolyte membranes. Dyes and metabolites, Environmental Testing
  • Chemical Properties4,40′-Oxydianiline is a white crystalline solid, or a beige powder.
  • Chemical PropertiesColorless crystalline
  • Chemical Properties4-Aminophenyl ether is a resin used in the manufacture of a variety of industrial products. For example as, insulating varnishes, flame-retardant fi bers, wire enamels, coatings, and fi lms. It is also used for the manufacture of other fi re-resistant products.
  • UsesBis(p-aminophenyl) Ether is a reagent used in the preparation of polyimide-silica composite membranes for gas separation techniques. In addition, it is used in the synthesis of polymer films for elect rolyte membranes.
  • Uses4,4'-diaminodiphenylether be used for preparation polyimide and epoxy resin material.
  • Uses4,4'-Oxydianiline has been used to produce polyimide resins.
  • Production Methods4-Aminophenyl ether was produced in relatively large volume (on the order of 100,000–1,000,000 lb) in the 1970s but has since declined significantly. The compound is used primarily in the production of polyimide and polyesterimide resins. These resins are used in the manufacture of temperature- resistant products such as wire enamels, coatings, film, insulating varnishes, and flame-retardant fibers.
  • General DescriptionOdorless colorless crystals or an odorless fine, beige powder.
  • Air & Water ReactionsInsoluble in water.
  • Reactivity Profile4,4'-Oxydianiline oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick, 1979 p.151-154, 164]. A mixture of liquid air and diethyl ether exploded spontaneously [MCA Case History 616(1960)].
  • Health Hazard4-Aminophenyl ether is highly toxic to animals. There is suffi cient evidence as a carcinogenicity and has caused adenomas and carcinomas in the thyroid and liver of experimental rats.
  • Fire Hazard4,4'-Oxydianiline is combustible.
  • Safety ProfileConfirmed carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Poison by intraperitoneal route. Moderately toxic by ingestion. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx
  • Potential ExposureIntermediate in the manufacture of high-temperature-resistant, straight polyimide and poly (esterimide) resins capable of withstanding temperatures of Up to 480°C for short periods or 260°C for prolonged periods of time. Some p-phenylenediamine compounds have been used as rubber components, and DFG warns of danger of skin sensitization.
  • Carcinogenicity4,4′-Oxydianiline is reasonably anticipated to be a human carcinogenbased on sufficient evidence of carcinogenicity from studies in experimental animals.
  • ShippingUN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.
  • IncompatibilitiesIncompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, and epoxides. Slowly hydrolyzes in water, releasing ammonia, and forming acetate salts. Decomposes at 265C releasing toxic oxides of nitrogen, sulfur, and carbon. Decomposed by strong ultraviolet light.
  • Waste DisposalIncineration with provision for nitrogen oxides removal from flue gases.
