Aniline, also known as aminobenzene or phenylamine is an aromatic organic compound, the simplest aromatic amine. It has the chemical formula C6H7N or more convenient C6H5NH2.

Properties

Chemical

Aniline can be oxidized with potassium permanganate to nitrobenzene. This reaction is the opposite of aniline's synthesis.

Physical

Aniline is a colorless liquid with a strong ammonia or fish-like odor. It is miscible with water and most organic solvents.

Availability

Aniline is sold by various chemical suppliers.

Preparation

There are several ways to make aniline. The most common way involves the reduction of nitrobenzene with hydrogen in the presence of a metal catalyst.

Another method of obtaining aniline is through the destructive distillation of Indigo.

Projects

  • Make trinitroaniline

Handling

Safety

Aniline is toxic in large quantities and it's best to avoid being exposed to it for too long.

Storage

Aniline should be stored in closed bottles, away from any source of ignition and copper alloys.

Disposal

Aniline can be destroyed by oxidizing it with Fenton's reagent.
