| Applications | Uses: Commercial production of PCBs stopped in 1977 in the US, [HSDB], 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), Methods of Manufacturing: 2, 4, 5-TRICHLOROANILINE IS COUPLED WITH 1, 2, 3-TRICHLOROBENZENE 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, Formulations, Preparations: Detected at trace levels in Clophen A50 and A60., U.S. Imports: (1986) No Data, U.S. Exports: (1986) No Data, General Manufacturing Information: DOMESTIC, USA, PRODUCTION OF POLYCHLORINATED BIPHENYLS WAS STOPPED IN OCTOBER 1977, POLYCHLORINATED BIPHENYLS |
