| | 4,4'-Oxydianiline Usage And Synthesis |
| Uses | Bis(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 Properties | Colorless crystalline | | Chemical Properties | 4,40′-Oxydianiline is a white crystalline solid,
or a beige powder. | | Chemical Properties | 4-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. | | Uses | Bis(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. | | Uses | 4,4＇-Oxydianiline has been used to produce polyimide resins. | | Uses | 4,4'-diaminodiphenylether be used for preparation polyimide and epoxy resin material. | | Production Methods | 4-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. | | Definition | ChEBI: 4-Aminophenyl ether is an aromatic ether. | | General Description | Odorless colorless crystals or an odorless fine, beige powder. | | Air & Water Reactions | Insoluble in water. | | Reactivity Profile | 4,4'-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 Hazard | 4-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 Hazard | 4,4'-Oxydianiline is combustible. | | Flammability and Explosibility | Notclassified | | Safety Profile | Confirmed 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 Exposure | Intermediate 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. | | Carcinogenicity | 4,4′-Oxydianiline is reasonably anticipated to be a human carcinogenbased on sufficient evidence of carcinogenicity from studies in experimental animals. | | Shipping | UN2811 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. | | Incompatibilities | Incompatible 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 Disposal | Incineration with provision
for nitrogen oxides removal from flue gases. |
