Usage

Description

AROCLOR 1248, 1X1ML, ISO, 1UG/ML is a viscous, oily, light yellow to yellow-green liquid with a faint odor. It is a type of polychlorinated biphenyl (PCB) that is nonflammable, mobile, and dense.

Uses

Used in Epoxy Resin Industry:
AROCLOR 1248, 1X1ML, ISO, 1UG/ML is used as an additive to improve adhesion and resistance to chemical attack in epoxy resins.
Used in Electric Condenser Industry:
AROCLOR 1248, 1X1ML, ISO, 1UG/ML is used as an insulator fluid for electric condensers.
Used in High-Pressure Lubricant Industry:
AROCLOR 1248, 1X1ML, ISO, 1UG/ML is used as an additive in very high-pressure lubricants.
Used in Fluorescent and High-Intensity Discharge Ballast Industry (Manufactured Prior to 1979):
AROCLOR 1248, 1X1ML, ISO, 1UG/ML was used in fluorescent and high-intensity discharge ballasts as a substitute for silicone oils.
Used in Vacuum Pump Industry:
PCB-1248 and PCB-1254 were used as substitutes for silicone oils in vacuum pumps.
Used in Insecticide Formulation Industry:
At a concentration of 5 to 25 wt%, AROCLOR 1248, 1X1ML, ISO, 1UG/ML increased the effective kill-life of the lindane spray up to 10 times. It may have been used in chlordane and BHC insecticide formulations.

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.

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.
