WebSynonyms: PCBs, chlorinated biphenyls, Aroclor, Clophen, Fenclor, Kaneclor, Pyralene. Physical properties. PCBs range in appearance from colourless, oily liquids to more viscous and increasingly darker liquids, to yellow to black resins. The appearance depends on the chlorine content of the PCB. Some PCBs can exist as a vapour in air. WebGeneral Description PCBs are colorless oily liquids. Much denser than water and insoluble in water. May burn under exposure to intense heat or flames for prolonged periods of time. Primary hazard is persistence in the environment and potential for long term chronic environmental and health risks.

WebBiphenyl does not dissolve at all in water. Why is this? It is a very non-polar molecule, with only carbon-carbon and carbon-hydrogen bonds. It has some intermolecular forces bonding it to itself through nonpolar London dispersion forces, but it has no significant attractive interactions with very polar solvent molecules like water.

WebPolychlorinated Biphenyls (hereinafter abbreviated as PCBs in this paper) are aromatic compounds (that is, hydrocarbon compounds with a cyclic or ring-shaped structure) that do not occur naturally in the environment (nature). Chemically, PCBs consist of a biphenyl or biphenyl group (two benzene bonds) bonded to 10 chlorine or cl- atoms. WebPolychlorinated biphenyls (PCBs) have been used commercially since 1929 as dielectric and heat exchange fluids and in a variety of other applications. However, the distribution …
