PCBs (Polychlorinated biphenyls) are man made organic chemicals known as chlorinated hydrocarbons. Carnauba wax is not very soluble in chlorinated or aromatic hydrocarbons. Traditional solvents are often toxic or are chlorinated. It is not resistant to solvents, aromatics and some chlorinated hydrocarbons. I, dry cleaners began using chlorinated solvents. First, ethylene is chlorinated over a ferric chloride catalyst to produce 1,2-dichloroethane. Dioxins accumulate in food chains in a fashion similar to other chlorinated compounds (bioaccumulation). They are corrosive, and are incompatible with many chlorinated solvents. Some water pollutants, especially chlorinated organic compounds, can be destroyed sonochemically. It is prone to stress cracking in chlorinated solvents. Potential contaminated water should also be chlorinated. These fall into two classes - halogenated (chlorinated) and non-halogenated. The product contains significant amounts of chlorinated benzoic acid derivatives. The water is clarified and filtered then chlorinated and fluoridated. It has the highest solvent power of any chlorinated hydrocarbon.
