Brief Overview

Chlorinated paraffins (CPs) are complex mixtures of polychlorinated n-alkanes. The chlorination degree of CPs can vary between 30 and 70 wt%. CPs are subdivided according to their carbon chain length into short chain CPs (SCCPs, C 10–13 ), medium chain CPs (MCCPs, C 14–17 ) and long chain CPs (LCCPs, C17 ). Depending on chain length and chlorine content, CPs are colorless or yellowish liquids or solids.

Manufacturing process:
Chlorinated paraffins are synthesized by reaction of chlorine gas with unbranched paraffin fractions (2% isoparaffins,100 ppm aromatics) at a temperature of 80 - 100 °C. The radical substitution may be promoted by UV-light.

Production of CPs for industrial use started in the 1930s. Currently, over 200 CP formulations are in use for a wide range of industrial applications, such as flame retardants and plasticisers, as additives in metal working fluids, in sealants, paints, adhesives, textiles, leather fat and coatings.
