Physical & Chemical Properties

Physical description & handling notes

• Pcb-1221 is a viscous oily liquid. (NTP, 1992)
• ... Colorless mobile oil
• Lower chlorinated Aroclors (1221, 1232, 1016, 1242, and 1248) are colorless mobile oils. Increasing chlorine content results in mixtures taking on the consistency of viscous liquids (Aroclor 1254) or sticky resins (Aroclors 1260 and 1262). Arclors 1268 and 1270 are white powders.
• PRACTICALLY ODORLESS
• 141-150 °C (Cleveland open cup)
• Miscible in non-polar organic solvents.

Documented Uses

• Formerly used in gas-transmission turbine hydraulics, rubber plasticizers, adhesives, and electrical capacitors.
• Used in heat transfer, hydraulic fluids, lubricants, and insecticides.
• Although the production and sale was discontinued in late 1977, it is still present in many of the ... capacitors now in use.
• Summary of former end uses for various Aroclors:
• PCBs were used as coolants and lubricants in transformers, capacitors, and other electrical devices (such as fluorescent lights and refrigerators) produced before 1977. PCBs may contaminate the air and water near hazardouc waste sites. In addition, PCBs bioaccumulate in the environment and may be found in fish, meat, and dairy products. (L4)
• PCBs /were/ ... prepared industrially by the chlorination of biphenyl with anhydrous chlorine in the presence of a catalyst such as iron filings or ferric chloride. The products are complex mixtures of chlorobiphenyls, whose degree of chlorination depends principally on the time of contact (12-36 hr) of the biphenyl with anhydrous chlorine. The crude product is blown with air, and a small amount of lime is added to remove hydrogen chloride and ferric chloride. The resulting chlorinated mixtures are batch-distilled
