    Nov 01, 2018· 1. Introduction. Chlorinated paraffins (CPs), also known as polychlorinated n-alkanes, are complex chlorinated derivatives of different diastereomers, isomers, and enantiomers (Houde et al., 2008; Serrone et al., 1987).CPs are commonly classified into three groups according to carbon chain length: short-chain chlorinated paraffins (SCCPs; C 10 –C 13), medium-chain chlorinated paraffins ...

  • Short-Chain Chlorinated Paraffins (SCCPs)

    Short- and medium- chain length chlorinated paraffins are liquids while longer chain, higher chlorinated paraffins are solids. The SCCPs are viscous liquids at room temperature and normal pressure. Vapor pressure of chlorinated paraffins generally decreases with increasing MW (a function of number of chlorine atoms).
