PDCB Paradichloro Benzene CAS 106-46-7 Raw Material For Mothball

What is PDCB?

PDCB, or para-dichlorobenzene, is a chlorinated aromatic compound. It is one of the three isomers of dichlorobenzene, with the chlorine atoms attached to the para positions on the benzene ring. PDCB appears as white, crystalline flakes or a solid, but it is also available in vaporized form.

Physical and Chemical Properties of PDCB

Molecular Formula: C6H4Cl2

Molecular Weight: 147.0 g/mol

Boiling Point: 174.5°C

Melting Point: 53°C

Density: 1.26 g/cm³

Solubility: Insoluble in water, but soluble in organic solvents such as alcohol, and chloroform.

Odor: Pungent, characteristic, similar to mothballs.

PDCB is characterized by its relatively low solubility in water and its ability to sublimate, releasing vapors into the air. This property makes it ideal for use in air fresheners and moth repellents, where vaporization is necessary.

Applications of PDCB

PDCB is widely used in several industries, particularly due to its strong deodorizing and disinfecting properties.

1. Moth Repellent

  • PDCB is commonly used in mothballs to protect fabrics and clothing from moth larvae. The vapor from PDCB repels moths and other insects, preventing damage to textiles such as wool.

2. Air Fresheners and Deodorizers

  • It is a key ingredient in many air fresheners and deodorizers because of its strong, long-lasting scent. It is often used in solid air fresheners, hanging bags, and even some toilet deodorizers.

3. Solvent in Chemical Synthesis

  • PDCB is used as a solvent and intermediate in the synthesis of various chemicals, including pesticides and herbicides.

4. Industrial Uses

  • It is used as a solvent in the manufacture of coatings, resins, and adhesives due to its ability to dissolve certain polymers and chemicals.

5. Disinfection

  • PDCB has disinfectant properties and is sometimes employed in sterilizing products and materials in industrial settings.

Safety and Handling of PDCB

Although PDCB is effective in its applications, it must be handled with caution due to its toxicity and potential environmental impact. Some key safety considerations include:

  • Toxicity: PDCB is harmful if inhaled, ingested, or absorbed through the skin. Exposure to high concentrations can cause respiratory problems, headaches, dizziness, and irritation of the skin and eyes.
  • Precautions: Always use PDCB in well-ventilated areas. Wear protective equipment, including gloves, goggles, and a respirator if handling large quantities.
  • Regulations: PDCB is classified as a hazardous air pollutant (HAP) by some environmental protection agencies due to its potential to contribute to air pollution.

Environmental Impact

PDCB is a volatile compound, and when used in mothballs or air fresheners, it can evaporate into the air, where it may contribute to indoor air pollution. Extended exposure to high levels of PDCB may pose health risks to humans and animals. Therefore, it is important to use PDCB products in accordance with safety guidelines and dispose of them responsibly to minimize environmental impact.

Conclusion

Para-dichlorobenzene (PDCB) is an important chemical with a variety of industrial, household, and commercial applications, particularly as a moth repellent, air freshener, and solvent. Its physical properties, such as its ability to sublimate and its strong odor, make it effective for these uses. However, due to its toxicity and environmental impact, safe handling and proper disposal are essential to minimize risks.
