Chlorinated paraffins (CPs) are complex mixtures of polychlorinated n-alkanes classified based on carbon chain length and chlorine content. Here are some common CAS numbers for different types of chlorinated paraffins:

Short-Chain Chlorinated Paraffins (SCCPs, C10–13)

• Generic SCCPs: 85535-84-8

• Specific examples:

  • Chlorinated decanes (C10): 85535-85-9

  • Chlorinated undecanes (C11): 85535-86-0

  • Chlorinated dodecanes (C12): 85535-87-1

  • Chlorinated tridecanes (C13): 85535-88-2

Medium-Chain Chlorinated Paraffins (MCCPs, C14–17)

• Generic MCCPs: 85535-85-9 (sometimes overlaps with SCCP listings)

• Specific examples:

  • Chlorinated tetradecanes (C14): 85535-89-3

  • Chlorinated pentadecanes (C15): 85535-90-6

  • Chlorinated hexadecanes (C16): 85535-91-7

  • Chlorinated heptadecanes (C17): 85535-92-8

Long-Chain Chlorinated Paraffins (LCCPs, C18–30)

• Generic LCCPs: 63449-39-8

• Less standardized, as commercial LCCPs vary widely in composition.

Other Related CAS Numbers

• Chlorinated paraffin (unspecified): 61788-76-9

• Chlorinated alkanes (general): 63449-39-8

Regulatory Notes

• SCCPs (C10–13) are listed under the Stockholm Convention as persistent organic pollutants (POPs) and are restricted in many countries.

• MCCPs (C14–17) are under increasing regulatory scrutiny but are not yet globally banned.

• LCCPs (C18+) are less studied but may face future restrictions.

Chlorinated Paraffins (CPs) are industrial chemicals produced by chlorination of n-alkane (paraffin) fractions. They are classified based on carbon chain length and chlorine content (typically 30–70% by weight).

Types of Chlorinated Paraffins

1. Short-Chain Chlorinated Paraffins (SCCPs, C10–13)

   • CAS No.: 85535-84-8 (generic)

   • Regulation: Banned under the Stockholm Convention (POPs list) due to persistence, toxicity, and bioaccumulation.

   • Uses: Flame retardants, plasticizers, metalworking fluids.

2. Medium-Chain Chlorinated Paraffins (MCCPs, C14–17)

   • CAS No.: 85535-85-9 (generic, sometimes overlaps with SCCPs)

   • Regulation: Increasing restrictions (e.g., EU REACH, proposed for global regulation).

   • Uses: PVC plasticizers, lubricants, sealants.

3. Long-Chain Chlorinated Paraffins (LCCPs, C18–30)

   • CAS No.: 63449-39-8 (generic)

   • Regulation: Less restricted but under review (potential future bans).

   • Uses: High-temperature lubricants, adhesives.

Key Properties

• Appearance: Colorless to yellowish oily liquids or solids.

• Solubility: Insoluble in water, soluble in organic solvents.

• Stability: Resistant to degradation (persistent in the environment).

Common Applications

• Plasticizers (flexible PVC products)

• Flame retardants (rubber, paints, textiles)

• Metalworking fluids (cutting/forming lubricants)

• Adhesives & sealants

Regulatory Status

• SCCPs: Banned in EU, Canada, Japan, and others.

• MCCPs: Restricted in some regions (EU, UK).

• LCCPs: Still in use but monitored.

Here are the key properties of chlorinated paraffins (CPs), categorized by physical, chemical, and environmental characteristics:

1. Physical Properties

2. Chemical Properties

3. Environmental & Toxicological Properties

4. Technical Performance Properties

• Plasticizing Efficiency: Improves flexibility in PVC (compares to phthalates).

• Lubricity: Reduces friction in metalworking fluids.

• Acid Resistance: Stable in non-oxidizing acids.

• Electrical Insulation: Used in cable coatings.

Key Variations by Chain Length

Safety & Handling

• Storage: Keep in airtight containers (avoid moisture/heat).

• Decomposition: Avoid temperatures >200°C (risk of HCl release).

• Regulatory Notes: SCCPs are banned in many countries; MCCPs restricted under REACH.

Chlorinated paraffins are known by various alternative names, trade names, and abbreviations depending on their chain length, chlorine content, and regional usage. Here’s a comprehensive list:

IUPAC & Chemical Names

• Chlorinated alkanes

• Polychlorinated alkanes (PCAs)

• Chlorinated n-alkanes

• Alkanes, chloro derivatives

Common Abbreviations

• CPs (Chlorinated Paraffins)

• SCCPs (Short-Chain Chlorinated Paraffins, C10–13)

• MCCPs (Medium-Chain Chlorinated Paraffins, C14–17)
