登记用途：Uses: Although the production and sale was discontinued in late 1977、it is still present in ... capacitors now in use.、Chlorinated biphenyls and related compounds、Summary of former end uses for various Aroclors:、Table: Aroclor [Table#5901]、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: 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 to remove color and traces of hydrogen chloride and ferric chloride.、Polychlorinated biphenyls、Impurities: Almost without exception、polychlorinated biphenyls contain various levels of polychlorinated dibenzofurans as contaminants.、Formulations、Preparations: The approximate distribution of chlorinated biphenyls in Aroclor 1016 are as follows: <1.0% mono-、21.2% di-、51.5% tri-、27.3% tetra-、<0.6% pentachlorobiphenyl.、Aroclor 1016 has an approximate chlorine content of 42%.、Aroclor 1016 and Aroclor 1242 are primarily trichlorobiphenyls. The major difference between these two products is the lower penta-、and hexachlorobiphenyl content of Aroclor 1016.、U.S. Production:、Production、discontinued in late 1977、General Manufacturing Information: The Aroclors are characterized by four digit numbers. The first two digits indicate that the mixture contains biphenyls (12)、triphenyls (54) or both (25、44)、the last two digits give the weight percent of chlorine in the mixture (e.g.、Aroclor 1242 contains biphenyls with approximately 42% chlorine).、An exception to、4 digit with second pair of numbers represent the percentage by weight of chlorine、nomenclature is Aroclor 1016、which contains 40 percent chlorine by weight、Aroclor 1016 was first sold in 1971.、When it was determined that there was a significant environmental problem associated with the more heavy chlorinated species、Monsanto prepared a new mixture that was limited primarily to the mono-、di-、and trichloro isomers. This product carried the designation Aroclor 1016.、Askarels were often、but not always、a mixture of trichlorobenzenes with PCBs to achieve desired viscosities to permit handling the dielectric as an oily fluid. The capacitor askarels include neat Aroclors 1242、1254、and 1016 and a mixture of 75% Aroclor 1254 and 25% trichlorobenzene. The most common transformer askarels were 60% Aroclor 1260、40% trichlorobenzene (Type A) and 70% Aroclor 1254、30% trichlorobenzene (Type D).。
