Water absorption is less than 0.1wt% after 24 hours. However, PBT is not recommended for extended use in water or aqueous solutions above 52C (125F).112 PBT plastics are also intrinsically resistant to detergents, weak acids and bases, aliphatic hydrocarbons, fluorinated hydrocarbons, alcohols, ketones, ethylene glycol, carbon tetrachloride, oils, and fats at room temperature. They also exhibit good resistance to motor oil, gasoline, transmission fluids, and brake fluids at temperatures to 60C (HOF).113... 

Chlorinated aliphatic solvents used for sulfonation include methylene chloride, chloroform, carbon tetrachloride, ethylene dichloride, trichloroethylene, and tetrachloroethylene. Fluorinated-chlorinated solvents find use in the laboratory. Such solvents have been employed to preswell... 

Carbon tetrachloride, trichloroethylene, and polyvinyl chloride (PVC) are well known hepatotoxins. Nephrotoxins are the chemicals that affect the kidneys. Since a large amount of blood circulates through the kidneys, they are susceptible to chemical attack if the blood contains a toxin. Heavy metals, chlorinated and fluorinated hydrocarbons, carbon disulfide, and ethylene glycol are some examples of kidney poisons. Many of these toxins can enter the body through inhalation or absorption. Toxins can be detected through medical surveillance, which monitors metabolites in the urine. Metabolites are the products formed by the toxin after it undergoes changes due to metabolism. 

The primary uses of 1,2-dichloroethane (ethylene dichloride), 1,1-di-chloroethane, chloroform, and carbon tetrachloride are as feed stocks for the production of chlorinated and fluorinated hydrocarbons. Ethylene dichloride is used in the preparation of protein concentrates and in the extraction of natural oils. Chloroform is a chemical intermediate in the manufacture of plastic, dyes, resins, and fire extinguishing products. It is used as an extraction solvent for various pharmaceutical products as well as a reactant in the preparation of analgesics and anthelmintic drugs. Miscellaneous uses of carbon tetrachloride include synthesis of organic chemicals, dyes, drugs, and lubricants. 

Substitution Where feasible, less toxic solvents should be substituted for highly toxic solvents. As discussed earlier, aqueous systems are the least toxic and are nonflammable. Water with safe additives may be effective however, if water has insufficient solvent power, safety solvents, such as aliphatic hydrocarbons and fluorinated hydrocarbons should be considered before the more toxic solvents, such as toluene, ethylene dichloride, and trichloroethylene. When the more toxic solvents must be used, control measures such as local exhaust ventilation systems should be employed to remove volatile vapors and mists at the source. A review system should be in place to identify highly toxic solvents such as benzene, carbon tetrachloride, and gasoline and to ensure that appropriate substitutions are considered and/or controls are in place to address potential hazards. 

Product distributions from the disproportionation of l,l,2,3-tetrachloro-3, 3-difluoropropene (2CFsCFCCl CClj- CFj Ca Cai+CFa,CCI CCIg 2CFCljCCl CCl4- CF,ClCa CCl, + CCl,Ca Ca,) at 50 C with aluminium halides, titanium tetrachloride, and antimony pentachloride have been determined. Formation of the bromo-olefin CF,-CCl CBrCl in the reaction with aluminium bromide was rationalized in trams of the HSAB concept, and related known reactions were interpreted similarly. Replacement of vinylic fluorine by iodine has been shown to occur udien tetrafluoro-ethylene or chlorotrifluoroethylene is treated with methyl iodide and aluminium chloride. ...
