| | AROCLOR 1248, 1X1ML, ISO, 1UG/ML Usage And Synthesis |
| Chemical Properties | Viscous, oily, light yellow to yellow-green, mobile, dense, nonflammable liquid with a faint odor | | Uses | In epoxy resins to improve adhesion and resistance to chemical attack; as an insulator fluid
for electric condensers and as an additive in very high pressure lubricants. In fluorescent and highintensity
discharge ballasts manufactured prior to 1979 (U.S. EPA, 1998).
PCB-1248 and PCB-1254 were used instead of silicone oils in vacuum pumps (Monsanto,
1960).
At a concentration of 5 to 25 wt %, increased the effective kill-life of the lindane spray up to 10
times. May have been used in chlordane and BHC insecticide formulations (Monsanto, 1960). | | Definition | ChEBI: 3,3',5,5'-tetrachlorobiphenyl is a tetrachlorobiphenyl that is biphenyl in which both phenyl groups are substituted by chlorines at positions 3 and 5. It is a tetrachlorobiphenyl and a dichlorobenzene. | | General Description | Viscous oily liquid. | | Air & Water Reactions | Insoluble in water. | | Reactivity Profile | Simple aromatic halogenated organic compounds are very unreactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. | | Health Hazard | ACUTE/CHRONIC HAZARDS: Toxic irritant. Hazardous decomposition products. | | Fire Hazard | Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot. | | Safety Profile | Suspected human
carcinogen. Moderately toxic by skin
contact. Experimental teratogenic and
reproductive effects. When heated to
decomposition it emits toxic fumes of Cl-.
Used in heat transfer, hydraulic fluids,
lubricants, and insecticides. See also
POLYCHLORINATED BIPHENYLS. | | Environmental fate | Biological. Reported degradation products by the microorganism Alcaligenes BM-2 for a
mixture of polychlorinated biphenyls include monohydroxychlorobiphenyl, 2-hydroxy-6-
oxochlorophenylhexa-2,4-dieonic acid, chlorobenzoic acid, chlorobenzoylpropionic acid, chlorophenylacetic
acid, and 3-chlorophenyl-2-chloropropenic acid (Yagi and Sudo, 1980). When
PCB-1248 (5 and 10 mg/) was statically incubated in the dark at 25 °C with yeast extract and
settled domestic wastewater inoculum, no biodegradation was observed (Tabak et al., 1981).
Chemical/Physical. Heating PCB-1248 in oxygen at 270–300 °C for 1 wk resulted in the
formation of mono-, di-, tri-, tetra-, and pentachlorodibenzofurans (PCDFs). At temperatures
greater than 330 °C, PCDFs decompose (Morita et al., 1978).
PCB-1248 will not hydrolyze to any reasonable extent (Kollig, 1993).
When PCB-1248 was heated up to 315 °C in a closed system, no appreciable decomposition
was observed (Monsanto, 1960).
Mackay and Wolkoff (1973) estimated an evaporation half-life of 58.3 min from a surface water
body that is 25 °C and 1 m deep. |
