    03.10.2006· 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, C >17).

    The analysis of persistent organic pollutants in environmental samples is a challenge due to the very large number of compounds with varying chemical and physical properties. Chlorinated paraffins (CPs) are complex mixtures of chlorinated n-alkanes with varying chain lengths (C10 to C30) and degree of chlorination (30 to 70% by weight). Their physical-chemical properties make these compounds ...

    Jan 12, 2010· Abstract. Commercial chlorinated paraffins (CPs) are derived from the free radical chlorination of n-alkane mixtures.Starting mixtures used in the synthesis fall into three categories: C 10 –C 13 (short); C 14 –C 17 (medium) and C 20 –C 30 (long). This results in complex mixtures containing significant numbers of constitutional and optical isomers.
