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.
General Description
Odorless colorless crystals or an odorless fine, beige powder.
Reactivity Profile
4,4'-DIAMINODIPHENYL ETHER(101-80-4) 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)].
Air & Water Reactions
Insoluble in water.
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.
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.
Fire Hazard
This chemical is combustible.
First aid
Move victim to fresh air. Call 911 or emergency
medical service. Give artificial respiration if victim is not
breathing. Do not use mouth-to-mouth methods if victim
ingested or inhaled the substance; give artificial respiration
with the aid of a pocket mask equipped with a one-way
valve or other proper respiratory medical device?
Administer oxygen if breathing is difficult. Remove and
isolate contaminated clothing and shoes. In the case of contact
with substance, immediately flush skin or eyes with
running water for at least 20 minutes. For minor skin contact,
avoid spreading material on unaffected skin. Keep victim
warm and quiet. Effects of exposure (inhalation,
ingestion, or skin contact) to substance may be delayed.
Ensure that medical personnel are aware of the material(s)
involved and take precautions to protect themselves.
Medical observation is recommended for 24－48 hours after
breathing overexposure, as pulmonary edema may be
delayed. As first aid for pulmonary edema, a doctor or
authorized paramedic may consider administering a drug or
other inhalation therapy.
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.
Description
4,40-Oxydianiline is a white crystalline solid,or a beige powder. Molecular weight =200.26; Boilingpoint ≥300℃ (sublimes); Freezing/Meltingpoint = 186-187℃; Flash point =219℃. Very slightlysoluble in water.
Waste Disposal
Incineration with provision
for nitrogen oxides removal from flue gases.
Definition
ChEBI: 4-Aminophenyl ether is an aromatic ether.
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.
Flammability and Explosibility
Notclassified
Carcinogenicity
4,4′-Oxydianiline is reasonably anticipated to be a human carcinogenbased on sufficient evidence of carcinogenicity from studies in experimental animals.
