PERCHLOROETHYLENE

Perchloroethylene (PCE), also known as tetrachloroethylene, is a chlorinated hydrocarbon widely used as a solvent. It is a colorless liquid with a sweet, ether-like odor and is nonflammable, making it ideal for applications in dry cleaning, degreasing, and various chemical processes.

Applications

1. Dry Cleaning

Perchloroethylene is the primary solvent used in the dry-cleaning industry.

Uses:

• Removes stains and dirt from fabrics without water.
• Effective for delicate textiles that cannot withstand traditional washing.

Benefits:

• High cleaning efficiency.
• Minimal fabric damage.

2. Metal Degreasing

Perchloroethylene is commonly used in vapor degreasing processes to clean metal parts.

Uses:

• Removes oils, greases, and other contaminants from metal surfaces.
• Prepares metal components for coating or assembly.

Benefits:

• High solvency power for industrial oils and greases.
• Suitable for precision cleaning applications.

3. Chemical Manufacturing

Perchloroethylene serves as a feedstock in producing fluorocarbons and other chemicals.

Uses:

• Raw material in the synthesis of hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons (HCFCs).
• Intermediate in producing specialty chemicals.

Benefits:

• Stable chemical structure supports high-purity production.

4. Industrial Solvent

Perchloroethylene is used in paint removers, adhesives, and coatings.

Uses:

• Dissolves resins, oils, and waxes in industrial formulations.
• Effective in cleaning and stripping applications.

Benefits:

• High solvency for diverse substances.
• Nonflammable nature enhances workplace safety.

5. Laboratory Applications

Perchloroethylene is used in scientific research and as a solvent in analytical methods.

Uses:

• Sample preparation for chromatography.
• Cleaning laboratory equipment.

Benefits:

• High purity ensures consistent analytical results.

Safety and Handling

Hazards

• Inhalation: Can cause dizziness, headaches, or respiratory irritation. Prolonged exposure may affect the nervous system.
• Skin Contact: May cause irritation or dermatitis.
• Eye Contact: Can irritate eyes upon direct contact.
• Ingestion: Toxic if swallowed.

Precautions

• Use in a well-ventilated area or under fume hoods.
• Wear appropriate personal protective equipment (PPE), including gloves, safety goggles, and respiratory protection.
• Avoid skin and eye contact.

First Aid Measures

• Inhalation: Move to fresh air immediately. Seek medical attention if symptoms persist.
• Skin Contact: Wash with soap and water; remove contaminated clothing.
• Eye Contact: Rinse thoroughly with water for at least 15 minutes.
• Ingestion: Do not induce vomiting. Seek medical help immediately.

Storage

• Store in tightly sealed containers in a cool, dry, and well-ventilated area.
• Keep away from heat, sparks, or open flames.

Disposal

• Dispose of according to local environmental regulations. Do not release into drains or the environment.
