Products Description of Aniline CAS#62-53-3
Aniline is the simplest primary aromatic amine, a compound formed by replacing a hydrogen atom in the benzene molecule with an amino group. It is a colorless, oily, flammable liquid with a strong odor. Its melting point is -6.3°C, boiling point is 184°C, relative density is 1.0217 (20/4°C), refractive index is 1.5863, flash point (open cup) is 70°C, ignition point is 770°C according to Chemicalbook, and it decomposes when heated to 370°C. It is slightly soluble in water and easily soluble in organic solvents such as ethanol, ether, and chloroform. It turns brown when exposed to air or sunlight. It can be distilled by steam, and a small amount of zinc powder is added during distillation to prevent oxidation. 10-15ppm of NaBH4 can be added to the purified aniline to prevent oxidation and deterioration.
