Its chemical formula is CCl 4. It contains carbon in its +4 oxidation state and chloride ions. Properties. It is a colorless liquid. It smells like ether. It evaporates quite quickly. It can EC Number: Quantity Value Units Method Reference Comment; Δ f H° gas ± kJ/mol: AVG: N/A: Average of 6 values; Individual data points Quantity Value Units Method Reference Comment; S° gas,1 bar J/mol*K. This test method covers the determination of the activation level of activated carbon. Carbon tetrachloride (CCl 4) activity is defined herein as the ratio (in percent) of the weight of CCl 4 adsorbed by an activated carbon sample to the weight of the sample, when the carbon is saturated with CCl 4 under conditions listed in this test method.

Carbon tetrachloride (CCl 4) is a powerful hepatotoxin used extensively to generate liver necrosis and steatosis in rats, with the free radical generation as the possible mechanism of action. , Although the OS involved in CCl 4 intoxication is unlikely to occur during physiopathological conditions, CCl 4 intoxication in rats provides. Carbon tetrachloride, also called tetrachloromethane, a colourless, dense, highly toxic, volatile, nonflammable liquid possessing a characteristic odour and belonging to the family of organic halogen compounds, used principally in the manufacture of dichlorodifluoromethane (a refrigerant and propellant).. First prepared in by the reaction of chloroform with chlorine, carbon .   CAS number: 56–23–5 NIOSH REL: 2 ppm ( mg/m 3) minute STEL; NIOSH considers carbon tetrachloride to be a potential occupational carcinogen as defined by the OSHA carcinogen policy [29 CFR ]. Current OSHA PEL: 10 ppm TWA, 25 ppm CEILING, ppm 5-min MAXIMUM PEAK in any 4 hours. OSHA PEL: 2 ppm ( mg/m 3) TWA . Carbon tetrachloride is a clear, nonflammable liquid which is almost insoluble in water. (1) Carbon tetrachloride has a sweet characteristic odor, with an odor threshold above 10 ppm. (1) The vapor pressure for carbon tetrachloride is mm Hg at 20 C, and its log octanol/water partition coefficient (log K ow) is (1) Conversion Factors.

Carbon tetrachloride (CCl 4) is regarded as highly toxic. It is a known animal carcinogen and a potential human carcinogen. CCl 4 has become a model for the study of agents that cause localized cellular injury via a free-radical mechanism. This monograph is .   Carbon tetrachloride is a manufactured chemical that does not occur naturally. It is a clear liquid with a sweet smell that can be detected at low levels. It is also called carbon chloride, methane tetrachloride, perchloromethane, tetrachloroethane, or benziform. Carbon tetrachloride is most often found in the air as a colorless gas. It is not flammable and does not . Also known as: Carbon tet, Perchloromethane, CCl4, Carbon chloride, Tetrachloromethane, Perc Chemical reference number (CAS): Carbon tetrachloride (Carbon tet) is a non-flammable colorless liquid with a heavy, sweet odor. Before , carbon tet was widely used as a cleaning fluid in home and industry. Until , the chemical was used as a grain fumigant. Carbon tetrachloride was tested for carcinogenicity by various routes of administration. It produced liver neoplasms in mice and rats and mammary neoplasms in rats following subcutaneous injection. In one study in mice by inhalation, an increased incidence of phaeochromocytomas was reported. In experiments involving administration of carbon.
