| 应用领域 | Uses: Summary of former end uses for various Aroclors:、Table: Aroclor [Table#5903]、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、Formulations、Preparations: PCB congeners in weight percent are: biphenyl、0.1%、Cl1、31、Cl2、24、Cl3、28、Cl4、12、Cl5、4、Cl6、<0.1.、Consumption Patterns: Total USA sales in 1970 amounted to 33.2 million kg of PCBs and comprised ... 118 thousand kg Aroclor 1232.、U.S. Production:、Production、was discontinued in October 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). |
