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).

Chlorinated Paraffins (CPs) are straight-chain hydrocarbons that have been chlorinated. CPs are classified according to their carbon-chain length and percentage of chlorination, with carbon-chain lengths generally ranging from C10 to C30 and chlorination from approximately 35% to …

Chlorinated paraffins (CPs) are high production volume chemicals and ubiquitous environmental pollutants. In particular, data about the environmental fate of medium-chain (MCCPs, C14–C17) and long-chain (LCCPs, C≥18) CPs are urgently needed. Their analysis requires elaborate analytical methods and representative analytical standards.

Short‐chain chlorinated paraffins (SCCPs) are persistent compounds that are included in the list of priority substances in the field of water policy of the European Union in 2001. In this paper, a method based on liquid–liquid extraction and gas chromatography with electron capture detection (GC‐ECD) is evaluated to be proposed for the routine analysis of SCCPs in environmental water.

Chlorinated paraffins (CPs) are high production volume chemicals, but data about their environmental fate are scarce. CP mixtures composed of thousands of isomers represent a major challenge for quantification at low levels in environmental samples. Here, we present a novel analytical method for analysis of short-chain, medium-chain, and long-chain CPs in a single injection, that also yields ...

02.02.2016· long-chain chlorinated paraffins C20-C30 (long) CP mixtures are extremely complex, with over 10's of thousands of congeners and isomers, which makes separation by GC very challenging. NCI-LRMS is well-suited for routine analysis, however it is subject to the interferences and overlap from other polychlorinated pollutants and CPs with the same nominal mass.
Chat OnlineThe global chlorinated paraffin market is extremely fragmented, as per Transparency Market Research on the basis of a recently published report. This is mainly due to the presence of innumerable players in the market. With expanding product portfolios coupled with increasing number of players, the competition is expected to further intensify.

03.10.2019· Many methods for quantifying chlorinated paraffins (CPs) yield only a total concentration of the mixture as a single value. With appropriate analytical instrumentation and quantification methods, more reliable and detailed analysis can be performed by quantifying total concentrations of short-, medium-, and long-chain CPs (SCCPs, MCCPs, and LCCPs), and in the current optimal situation by ...
