应用领域

登记用途：Uses: Formerly used in electrical transformers、hydraulic fluids、plasticizer in synthetic resins and dedusting agents. Although the production and sale was discontinued in late 1977、it is still present in many of the transformers and capacitors now in use.、As of Jan 1979、Aroclors、including Aroclor 1260、are no longer used in the production of capacitors and transformers. Nevertheless、the life expectancy of transformers containing PCBs is > 30 yrs and the life expectancy of capacitors ranges from 10 to 20 yrs、depending on the electrical application ... In 1981、an estimated 131、200 transformers containing PCBs were in service in the US、representing approx 1% of all operational transformers.、Summary of former end uses for various Aroclors:、Table: Aroclor [Table#3667]、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、The approximate distribution of chlorinated biphenyls in Aroclor 1260 is: <0.3% tri-、<0.3% tetra-、9.2% penta-、46.9% hexa-、36.9% hepta-、6.3% octa-、and 0.7% nonachlorobiphenyl.、Impurities: Polychlorinated naphthalenes have also been identified in small quantities in、Aroclor 1260、.、PCDF Impurities in ppm: Cl3、0.01、Cl4、0.2-0.8、Cl5、0.26-0.9、Cl6、0.3-0.5、Cl7、1.3. Toxic PCDF levels: 2、3、7、8-TCDF、0.013 ppm、1、2、4、8-、8-PECDF、0.048、0.056、9-、0.5、6、8-HXCDF、0.12、8、9-HXCDF、0.19、0.027.、Concns of chlorinated dibenzofurans in commercial Aroclor mixtures: tetrachloro、0.1-0.8 ug、g、pentachloro-、0.3-3.6 ug、hexachloro-、0.3-1.9 ug、Formulations、Preparations: Aroclor 1260 is a polychlorobiphenyl mixture containing 60% chlorine. It is composed of 12% penta-、38% hexa-、41% hepta-、8% octa-、and 1% nona-chlorobiphenyls.、Congener composition: Cl4、1%、12%、38%、41%、Cl8、8%、Composition: pentachlorobiphenyls 12%、hexachlorobiphenyls 38%、heptachlorobiphenyls 41%、octachlorobiphenyls 8%、nonachlorobiphenyl 1%.、Consumption Patterns: Not used commercially in USA、Domestic sales in millions of pounds of Monsanto's Aroclor 1260 in the United States from 1957 to 1970 are as follows: 7.6 (1957)、6.0 (1958)、6.6 (1959)、7.3 (1960)、6.5 (1961)、6.6 (1962)、7.6 (1963)、8.5 (1964)、5.8 (1965)、5.9 (1966)、6.4 (1967)、5.3 (1968)、4.4 (1969)、and 4.9 (1970).、U.S. Production: (1982) Not produced commercially in USA、Production、discontinued in October 1977、U.S. Imports: (1978) 2.19 X10+8 g (Princpl Custms Dists) - PCBs、General Manufacturing Information: Total US sales in 1970 counted to 33.2 million kg and comprised ... 2.2 million kg Aroclor 1260 ...、Aroclor 1260 is the formulation used mostly in large capacitors and transformers. Federal Register、AUG 1979.、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).、... The average molecule in Aroclor 1260 has 6 substituent chlorines、but varying proportions of species with greater and lesser halogen content are found in the mixture depending on the manufacturing process.、For more General Manufacturing Information (Complete) data for Aroclor 1260 (6 total)、please visit the HSDB record page.。
