Introduction of Tris(1,3-dichloropropyl) Phosphate (TDCP)

Introduction of Tris(1,3-dichloropropyl) Phosphate (TDCP)

1. Basic Information:

• Chemical name: Tris(1,3-dichloropropyl) phosphate (TDCP)
• Chemical formula: C₉H₁₅Cl₆O₄P
• Molecular weight: 430.90 g/mol
• CAS number: 13674-87-8
• Appearance: colorless or light yellow transparent liquid
• Boiling point: >200°C (decomposition)
• Density: 1.512 g/cm³ (25°C)

2. Chemical structure:

TDCP is formed by the esterification of phosphoric acid and three 1,3-dichloropropanol molecules, and its chemical formula is (ClCH₂CHClCH₂O)₃PO.

3. Physicochemical properties:

• Solubility:
  Easily soluble in organic solvents (such as ethanol, acetone, toluene, etc.).
  Poorly soluble in water.
• Stability:
  Chemically stable at room temperature.
  May decompose under high temperature or strong acid or alkali conditions.
• Flame retardancy:
  It has excellent flame retardant properties, mainly inhibiting combustion by releasing non-flammable gas and forming a carbon layer.

4. Application Areas:

TDCP is a highly effective flame retardant, widely used in the following fields:

• Flame retardant:
  Used in polyurethane foam, plastic, rubber, textiles and other materials to improve their flame retardant properties.
  Particularly suitable for soft and hard polyurethane foam, it is an important flame retardant additive in furniture, car seats, building materials and other fields.
• Plasticizer:
  As an auxiliary plasticizer, it is used to improve the flexibility and processing properties of materials.
• Other applications:
  Used in coatings, adhesives and electronic materials to provide flame retardant protection.

5. Safety and Environmental Protection:

• toxicity:
  TDCP is toxic and may irritate the skin, eyes and respiratory tract.
  Long-term exposure may cause damage to the liver and kidneys, and protective equipment must be worn during operation.
• Environmental impact:
  TDCP is not easily biodegradable and may accumulate in water and soil, causing potential harm to the environment.
  It has been listed as a potential environmental pollutant and its use and discharge must be strictly controlled.
• Regulatory restrictions:
  Due to its potential risks to the environment and health, TDCP is strictly restricted or banned in some countries and regions.

6. Storage and transportation:

• Storage conditions:
  Store in a cool, dry, well-ventilated place, away from fire and oxidants.
  Avoid high temperatures and direct sunlight.
• Transportation requirements:
  Transport as hazardous chemicals, avoid severe vibration and high temperatures.
  The package should be well sealed to prevent leakage.

7. Regulations and Standards:

• International regulations:
  It is necessary to comply with the chemical management regulations of various countries, such as the EU REACH regulations and the US TSCA.
  In some countries, TDCP has been included in the list of restricted substances.
• Chinese standards:
  It complies with the "Chemical Safety Data Sheet" (GB/T 16483) and other relevant standards.

Summary：

Tris(1,3-dichloropropyl) phosphate (TDCP) is a highly effective flame retardant widely used in polyurethane foam, plastics, rubber and other fields. Despite its excellent flame retardant properties, its use is strictly restricted due to its potential risks to human health and the environment. Special attention should be paid to safety and environmental protection requirements during use and storage to avoid harm to the human body and the environment.
