Ferric Chloride Anhydrous (FeCl₃) is a dark brown to black crystalline solid with a metallic luster. It is a highly corrosive, hygroscopic inorganic salt widely used as a chemical reagent, catalyst, and coagulant. In its anhydrous form, ferric chloride is free of water and has a high purity of approximately 98%. It readily dissolves in water, releasing heat and producing acidic solutions. Ferric chloride is valued for its strong Lewis acid properties, making it effective in a variety of industrial, laboratory, and environmental applications. It is commonly supplied as a solid crystalline powder or lumps and should be handled with care due to its corrosive nature.

Description

Ferric Chloride Anhydrous

Primary Uses 

  1. Water and Wastewater Treatment

    • Employed in the production of pigments, dyes, and other iron-containing chemicals.
  3. Electronics and Metal Processing
    • Applied in metal cleaning and pickling to remove rust and oxide layers.
    • Used in electroplating baths and as a mordant in textile dyeing.
  4. Laboratory and Analytical Applications
    • Serves as a reagent for qualitative and quantitative chemical analysis, particularly for detecting phenols and other organic compounds.
    • Used in the preparation of iron salts and complexes.

Secondary Uses 

  1. Catalyst in Polymerization
    • Utilized as a catalyst in polymer production and modification processes.
  2. Pharmaceutical Industry
    • Employed in trace amounts in certain pharmaceutical formulations and synthesis processes.
  3. Environmental Applications
    • Used in sludge dewatering and stabilization processes.
    • Helps in odor control and reduction of biological oxygen demand (BOD) in waste streams.

SAFETY HANDLING PRECAUTIONS

Safety Handling Precautions

  1. Personal Protective Equipment (PPE):
    • Chemical-resistant gloves (e.g., neoprene or nitrile)
    • Safety goggles or face shield
    • Protective lab coat or chemical-resistant clothing
    • Respiratory protection (dust mask or respirator) in dusty or fume-prone environments
  2. Handling Guidelines:
    • Avoid inhalation of dust and fumes
    • Use under a fume hood or in well-ventilated areas
    • Prevent contact with skin and eyes
    • Avoid moisture exposure to prevent hazardous hydrolysis
  3. Storage Measures:
    • Keep container tightly closed and dry
    • Store away from bases, water, and strong oxidizers
    • Protect from humidity and moisture
  4. Hygiene Practices:
    • Wash hands thoroughly after handling
    • Avoid eating, drinking, or smoking in handling areas
    • Clean equipment and surfaces regularly

First Aid Measures

  1. Inhalation:
    • Move affected person to fresh air immediately
    • Seek medical attention if respiratory irritation or distress occurs
  2. Skin Contact:
    • Remove contaminated clothing immediately
    • Wash affected skin thoroughly with soap and water
    • Seek medical attention for burns or persistent irritation
  3. Eye Contact:
    • Rinse eyes immediately with plenty of water for at least 15 minutes
    • Seek urgent medical attention
  4. Ingestion:
    • Do not induce vomiting
    • Rinse mouth with water
    • Seek immediate medical assistance

Firefighting Measures

  1. Fire Hazards:

  2. Extinguishing Media:
    • Use dry chemical, foam, or carbon dioxide (CO₂) extinguishers
    • Avoid using water directly on dry material as it may release heat and corrosive vapors
  3. Special Precautions:
    • Firefighters should wear full protective gear including self-contained breathing apparatus
    • Prevent contaminated runoff from entering water bodies
  4. Decomposition Products:
    • Hydrogen chloride gas, chlorine gas, iron oxides, and other toxic fumes
