    1/1/2005· 1. Introduction. Chlorinated paraffins (CPs) are industrially produced compounds of the general formula C n H 2n+2−z Cl z.CPs, classified into three categories: short chain (C 10 –C 13 SCCPs), medium chain (C 14 –C 17 MCCPs) and long chain (C >17 LCCPs) molecules of the alkane feedstock from which they are formed. The degree of chlorination varies between 10% and 72% …
