  De Novo Synthesis Mechanism of Polychlorinated Dibenzofurans from Polycyclic Aromatic Hydrocarbons and the Characteristic Isomers of Polychlorinated Naphthalenes

  摘要：

  Polychlorinated dibenzofurans (PCDFs) and polychlorinated naphthalenes (PCNs) are known to be emitted from municipal waste incinerators (MWIs) with polychlorinated dibenzo-p-dioxins (PCDDs). Two formation paths for PCDD/Fs could mainly work, which are condensation of the precursors such as chlorophenols and "de novo" formation from carbon. However the correlation between the chemical structure of carbon and the resulting PCDD/Fs still remains unknown. In this study, the PCDD/Fs formation from polycyclic aromatic hydrocarbons (PAHs) and CuCl was examined at 400 under 10% O-2. Coronene among the PAHs characteristically gave 1,2,8,9-T4CDF and the derivatives. These isomers clearly indicate that chlorination causes the cleavage of the C-C bonds in a coronene molecule and also that oxygen is easily incorporated from its outside to form 1,2,8,9-T4CDF. The symmetrical preformed structures in the coronene molecule enabled to amplify the de novo formation of the isomer. PCNs are also formed directly from these PAHs. Since there have been few reports on the formation mechanism of PCNs, this study will be a first step to know the whole formation paths. We also define the de novo synthesis as the breakdown reaction of a carbon matrix, since the word has been used without the precise definition.

  fuels. However, their combined emissions from the domestic burning of coal and wood would contribute only a few percent to annual U.K. emission estimates. Emissions of PAHs and PM10 were major contributors to U.K. national emission inventories. Major emissions were found from the domestic burning for Cl1,2,3DFs, while the contribution of PCDD/F-sigmaTEQ to total U.K. emissions was minor.

  The regiochemistry of the photolysis of three tetrachloronaphthalenes is sharply dependent upon the presence of triethylamine. Analysis of the steady state kinetics in the presence and absence of quenchers and triethylamine provides a mechanistic rationale in terms of triplet, triplet excimer, and singlet exciplex.

  Polyarylene sulfides are produced by polymerizing a dihalogen aromatic compound with an alkali metal hydrosulfide in the presence of a lithium halide in an organic polar solvent. In this polymerization, an alkali metal hydroxide and/or carbonate is added and a branching agent such as a trihalogen aromatic compound or a halogen aromatic nitro compound is used, if desired. The polyarylene sulfides have a high molecular weight and a less salt contents and a high degree of whiteness.
