Carbon Tetrachloride - an overview | ScienceDirect Topics
Carbon tetrachloride. Carbon tetrachloride (CCl4) is a potent hepatotoxin [107] and has been used extensively to produce liver fibrosis in rats and mice, and recently in monkeys [108]. A single dose leads to centrizonal necrosis and steatosis, whilst prolonged exposure leads to liver fibrosis, cirrhosis and HCC [109,110]. CCl 4 acts in two stages.
Carbon Tetrachloride - an overview | ScienceDirect Topics
Carbon tetrachloride (CCl4) is a colorless, highly volatile liquid with a sweetish (ethereal) odor similar to chloroform. It decomposes to highly toxic fumes of phosgene upon heating. Carbon tetrachloride is primarily used in the production of chlorofluorocarbons that are used as refrigerants. It has also been used as an anthelminthic, an ...

2000年6月1日 · Carbon tetrachloride (CTC), tetrachloroethylene (PCE), trichloroethylene (TCE) and 1,1,1-trichloroethane (TCA) were four of the most widely used cleaning and degreasing solvents in the United States. These compounds were also …
Carbon Tetrachloride - an overview | ScienceDirect Topics
Carbon tetrachloride is known to be metabolized by mouse and rat liver and kidney microsomes, by CYP2E1, to yield a trichloromethyl radical, which may be oxygenated to yield phosgene (Figure 2). Hydrolysis of phosgene would then result in the formation of CO 2 , a major in vivo and in vitro metabolite of carbon tetrachloride.
Catalytic dechlorination of carbon tetrachloride to combustible ...
2024年10月30日 · Carbon tetrachloride (CT), a common persistent pollutant in groundwater, has attracted widespread attention from environmental researchers. The dechlorination from CT to combustible hydrocarbons not only represents the removal of contaminants, but also offers the possibility of recovering carbon resources from water.
