General Description
Crystals or off-white lumpy solid.
Reactivity Profile
TRIPHENYLAMINE(603-34-9) neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
Air & Water Reactions
Insoluble in water.
Potential Exposure
Triphenylamine is used as a primary
photoconductor and in making photographic film coated on
photographic film bases.
Fire Hazard
The flash point of this chemical has not been determined, but TRIPHENYLAMINE is probably combustible.
First aid
Skin Contact: Flood all areas of body that
have contacted the substance with water. Don’t wait to
remove contaminated clothing; do it under the water
stream. Use soap to help assure removal. Isolate contaminated
clothing when removed to prevent contact by others.
Eye Contact: Remove any contact lenses at once.
Immediately flush eyes well with copious quantities of
water or normal saline for at least 20-30 minutes. Seek
medical attention. Inhalation: Leave contaminated area
immediately; breathe fresh air. Proper respiratory protection
must be supplied to any rescuers. If coughing, difficult
breathing or any other symptoms develop, seek medical
attention at once, even if symptoms develop many hours
after exposure. Ingestion: Contact a physician, hospital or
poison center at once. If the victim is unconscious or convulsing,
do not induce vomiting or give anything by mouth.
Assure that the patient’s airway is open and lay him on his
side with his head lower than his body and transport immediately
to a medical facility. If conscious and not convulsing,
give a glass of water to dilute the substance. Vomiting
should not be induced without a physician’s advice.
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, oxo acids, epoxides, aldehydes, ketones.
Chemical Properties
Monoclinic crystals from EtOAc.
Chemical Properties
Triphenylamine is a colorless crystalline solid.
Preparation
Triphenylamine can be prepared by the arylation reaction of diphenylamine.

Health Hazard
Triphenyl amine is considered
to have low systemic toxicity, but it may act as
a slight skin irritant.
Adverse effects have not been reported in
humans.
Carcinogenicity
Triphenyl amine was not mutagenic in
bacterial assays with or without metabolic
activation.
Purification Methods
Crystallise the amine from EtOH or from *benzene/absolute EtOH, diethyl ether and pet ether. It is sublimed under vacuum and carefully dried in a vacuum line. Store it in the dark under nitrogen. [Beilstein 12 IV 276.]
