light grey powder or crystals | [General Description]
Light gray to gray powder. Solutions show blue fluorescence. | [Reactivity Profile]
N-PHENYL-2-NAPHTHYLAMINE(135-88-6) may react with strong oxidizing agents . 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. Napthyl amines can be slowly hydrolyzed, releasing NH3 as a byproduct [N.L. Drake, Org. React. 1, (1942), 105]. | [Potential Exposure]
Phenyl-β-naphthylamine is used as a rubber antioxidant; as an inhibitor for butadiene; a stabilizer in lubricants and an intermediate in chemical synthesis. | [Fire Hazard]
Literature sources indicate that this chemical is combustible. | [First aid]
UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. | [Incompatibilities]
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 method 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 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 2448 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.
| [Description]
Phenyl-naphtylamine is an amine coumpound. Sensitization
was reported in patients with hypersensitivity
to rubber. | [Uses]
Formerly as an antioxidant in rubber
processing to impart heat, oxidation, and flexcracking resistance in natural rubber, synthetic
rubbers, and latexes; as a stabilizer in electricalinsulating silicone enamels | [Uses]
Formerly as an antioxidant in rubber
processing to impart heat, oxidation, and flexcracking
resistance in natural rubber, synthetic
rubbers, and latexes; as a stabilizer in electricalinsulating
silicone enamels | [Uses]
N-Phenyl-2-naphthylamine is used as an antioxidant in rubber processing; provides oxidation and flex-cracking resistance in natural rubber, synthetic rubbers, and
latexes; stabilizer in electrical-insulating silicone enamels; antioxidant in otiJer polymers, greases, lubricating oils, and transformer oils;
heat and light stabilizer; vulcanization accelerator; catalyst; polymerization inhibitor; component of rocket fuels, surgical plasters, and
tin-electroplating batiJs; chemical intermediate; an inhibitor for butadiene; in the production of seven dyes; in rubber products made
of natural rubber, styrene-butadiene, nitrile, butadiene, and chloroprene. | [Definition]
ChEBI: N-Phenyl-2-naphthylamine is a member of naphthalenes. | [Health Hazard]
N-phenyl-b-naphthylamine
(PBNA) is carcinogenic to experimental
animals in some studies. | [Carcinogenicity]
The IARC has concluded that there is
limited evidence for carcinogenicity to animals
and inadequate evidence for humans.10 ACGIH
considers PBNA to be a suspected human
carcinogen because b-naphthylamine is both an
impurity and a human metabolite of PBNA. | [Purification Methods]
Crystallise it from EtOH, MeOH, glacial acetic acid or *benzene/hexane. [Beilstein 12 H 1275, 12 I 535, 12 II 716, 12 III 2991.] |
