    Jan 01, 2020· 1. Introduction. Chlorinated paraffins (CPs) are chemicals produced by the chlorination of n-alkane feedstocks to different degrees, typically ranging from 40 to 70% of chlorine content by weight in commercial products.They are generally subdivided according to their chain length as short (SCCPs – C 10-C 13), medium (MCCPs – C 14-C 17), and long chain …

    Chlorinated paraffins (CPs), also known as polychlorinated n-alkanes (PCAs), are complex mixtures of carbon chains of variable length and a variable number of chlorine atoms.They are currently produced in high volumes (>1 million tons year –1 in China alone).Concerns are rising regarding their ubiquitous occurrence and high persistence in the environment, including detection in remote areas.

    For flame-retardant applications, chlorinated paraffins with approximately 70% chlorine are used; the chain length depends on the substrate: SCCPs have been used for rubber and soft plastics and longer chain length paraffins (C18-30) for rigid plastics such as polyesters and polystyrene (Zitko & Arsenault, 1974), but this is likely not the case ...

    Chlorinated paraffins (CPs) is the industrial term for polychlorinated n-alkanes mixtures with a chlorine content typically between 30-70% and a carbon chain length greater than nine [1]. Based on these carbon chain lengths, CPs are divided into short- (C 10-13), medium- (C 14-17), and long- (C >17) chain groups. Since 2017, short-chain CPs (SCCPs)

    Chlorinated paraffins are produced by chlorination of straight-chained paraffin fractions. The carbon chain length of commercial chlorinated paraffins is usually between 10 and 30 carbon atoms. Short-chained chlorinated paraffins is between C10 and C13. The production of SCCPs has decreased globally as jurisdictions have established control ...
