Documented Uses

• Found in commercial PCB's, their manufacturing facilities, and during destruction or degradation of products containing PCB's; [HSDB]
• PCB's not commercially produced in the US since 1977; [HSDB]
• /PCBs were/ used as heat-transfer fluids, organic diluents, lubricant inks, plasticizers, fire retardants, paint additives, sealing liquids, immersion oils, adhesives, dedusting agents, waxes, and as dielectric fluids for capacitors and transformers. /Polychlorinated biphenyls/
• /SRP: THIS PCB FOUND IN AROCLORS 1242, 1248, 1254, AND 1260; CLOPHENS A40 AND 50; KANECHLORS 300, 400, 500, AND 600 COENTERS ... FROM MANUFACTURING PLANTS, DURING DESTRUCTION OF MANUFACTURED ARTICLES CONTAINING PCBS IN MUNICIPAL & INDUSTRIAL WASTE-DISPOSAL BURNERS, THROUGH GRADUAL WEAR & WEATHERING OF PCB-CONTAINING PRODUCTS, & THROUGH LEACHING FROM LAND-FILL DUMPS. /POLYCHLORINATED BIPHENYLS/
• PCBs were used as coolants and lubricants in transformers, capacitors, and other electrical devices (such as fluorescent lights and refridgerators) produced before 1977. PCBs may contaminate the air and water near hazardous waste sites. In addition, PCBs bioaccumulate in the environment and may be found in fish, meat, and dairy products. (L4)
• 3,4- DICHLOROANILINE IS COUPLED WITH 1,2-DICHLOROBENZENE BY USING AN EXCESS OF THE LATTER REACTANT WHICH ALSO SERVES AS THE SOLVENT MEDIUM. THE COUPLING REACTION PROCEEDS SMOOTHLY AFTER THE ADDITION OF ISOAMYL NITRITE, AND THE PCB PRODUCT IS READILY ISOLATED AFTER A SERIES OF CHROMATOGRAPHIC PROCEDURES
