Toxic Chemistry: Short-Chain Chlorinated …
Chlorinated paraffins (CPs) are complex mixtures of certain organic compounds containing chloride: 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, C10–13), medium chain CPs (MCCPs, C14–17) and long chain CPs (LCCPs, C>17). Depending on chain length and …

Risk Management for Short-Chain Chlorinated Paraffins ...
The main path in which chlorinated paraffins (SCCP and MCCP) enter the environment is via emissions from metal and leather processing (in the form of waste water) and from waste treatment and the depositing of plastics (in the form of exhaust emissions and waste water). Short and medium-chain chlorinated paraffins

Analysis of Chlorinated Paraffins in Environmental ...
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.

1. Introduction. Chlorinated paraffins (CPs), also known as polychlorinated n-alkanes with chlorine degree ranging from 30% to 70% by mass, are a complex mixture of thousands of isomers, diastereomers, and enantiomers (Feo et al., 2009).CPs can be divided into short (SCCPs, C10-C13), medium (MCCPs, C14-17), and long chain CPs (LCCPs, >17) according to their carbon chain length (Wei et al., 2016).

Short chain chlorinated paraffins (SCCPs) containing 10 to 13 carbon atoms, mostly used as plasticizers and flame retardants, are not now in commerce in the US. The environmental impact of CPs has been a topic studied and debated for more than 25 years. Specific concerns are environmental persistence, bioaccumulation, and biodegradability. The debate has occurred, in part, because the …
