Aniline

Aniline is an organic compound with the formula C₆H₅NH₂. It is a clear to slightly yellow liquid with a characteristic odor, often described as sweet or fishy. Aniline is the simplest aromatic amine and is primarily used as a precursor in the production of industrial chemicals.

Applications: Aniline is a versatile chemical with numerous industrial applications:

• Dyes and Pigments: It is a critical raw material in the production of indigo and other dyes used in textiles, leather, and inks.
• Polyurethane Foam: Aniline is a key component in the production of methylene diphenyl diisocyanate (MDI), which is used to make polyurethane foams.
• Rubber Chemicals: It is used in the manufacture of antioxidants and accelerators in rubber processing.
• Pharmaceuticals: Aniline derivatives are used in the synthesis of a variety of pharmaceutical compounds.
• Agrochemicals: It is utilized in the production of herbicides, fungicides, and other agricultural chemicals.
• Explosives: Aniline is involved in the synthesis of certain explosives.

Handling and Storage:

• Handling:
  • Handle in a well-ventilated area, away from heat, sparks, and open flame.
  • Use appropriate personal protective equipment (PPE) including gloves, goggles, and protective clothing.
  • Avoid contact with skin, eyes, and clothing. Wash thoroughly after handling.
  • Avoid inhalation of vapors. Use with adequate ventilation or respiratory protection.
  • In case of spillage, absorb with an inert material and place in a chemical waste container.
• Storage:
  • Store in a cool, dry, well-ventilated area away from incompatible substances like strong oxidizers, acids, and alkalis.
  • Keep the container tightly closed when not in use.
  • Store in a container made of compatible materials, preferably steel or glass.
  • Protect from physical damage and direct sunlight.
  • Label the storage area clearly to prevent accidental mixing with incompatible chemicals.

Safety Precautions:

• Aniline is toxic and can be absorbed through the skin or inhaled. Prolonged exposure can cause methemoglobinemia, a condition where hemoglobin is altered, reducing its oxygen-carrying capacity.
• In case of contact with skin or eyes, rinse immediately with plenty of water and seek medical attention.
• In the event of a spill or leak, use appropriate spill control measures and personal protective equipment to minimize exposure.
