Aniline Sulphate

Aniline Sulphate, also known as aniline sulfate, is an organic salt with the chemical formula (C₆H₅NH₂)₂·H₂SO₄. It appears as a white crystalline powder and is the sulphate salt of aniline. Aniline Sulphate is used primarily in analytical chemistry as a reagent, particularly for the detection of nitrites and nitrates, as well as in the manufacturing of dyes and other chemicals.

Applications: Aniline Sulphate has several specialized applications:

• Analytical Chemistry: It is used as a reagent for the detection of nitrites and nitrates in various samples. The compound forms a blue or green color upon reaction, making it useful in qualitative tests.
• Dye Manufacturing: Aniline Sulphate is an intermediate in the synthesis of various dyes and pigments, especially in the production of indigo and other aniline-based dyes.
• Chemical Reagent: It is used in organic synthesis for the preparation of other aniline derivatives.
• Paper Industry: Aniline Sulphate is sometimes used in the treatment of paper to detect lignin content.

Handling and Storage:

• Handling:
  • Handle in a well-ventilated area, away from incompatible substances such as strong oxidizing agents.
  • Use appropriate personal protective equipment (PPE), including gloves, goggles, and protective clothing.
  • Avoid contact with skin, eyes, and clothing. Wash thoroughly after handling.
  • Minimize dust generation and accumulation. Avoid inhalation of dust or vapors.
  • In case of spillage, sweep up the material carefully and place it in a suitable waste container. Avoid raising dust.
• Storage:
  • Store in a cool, dry, well-ventilated area away from incompatible substances.
  • Keep the container tightly closed when not in use, and protect it from moisture.
  • Store in a container made of compatible materials, preferably glass or polyethylene.
  • Label the storage area clearly to prevent accidental mixing with incompatible chemicals.
  • Protect from physical damage and direct sunlight.

Safety Precautions:

• Aniline Sulphate is toxic and can be harmful if inhaled, ingested, or absorbed through the skin. It may cause respiratory tract irritation, skin irritation, and eye irritation.
• In case of contact with skin or eyes, rinse immediately with plenty of water and seek medical attention.
• In the event of ingestion, do not induce vomiting; seek medical assistance immediately.
• Ensure proper ventilation during handling to avoid inhalation of dust. Use appropriate respiratory protection if necessary.
