• Photoreactions of Polyhalobenzenes in Benzene. Formation of Terphenyls
  作者：Masahiro Nakada、Chihiro Miura、Hideaki Nishiyama、Futoshi Higashi、Toru Mori、Minoru Hirota、Tetsuo Ishii

  DOI：10.1246/bcsj.62.3122

  日期：1989.10

  Polychlorobenzenes, polybromobenzenes, and polychloropolybromobenzenes (C6H6−nXn) were photolyzed in benzene solutions; the products were analyzed by the GC/MS method. Both dehalogenation and phenylation were shown to take place competitively, producing (poly)halobenzenes bearing one less halogen atom (C6H7−nXn−1) and (poly)halobiphenyls (C6H6−nXn−1–C6H5) as the major products. Besides these products

  多氯苯、多溴苯和多氯多溴苯（C6H6−nXn）在苯溶液中光解；产物采用 GC/MS 方法分析。脱卤和苯基化都显示出竞争性，产生少一个卤素原子的（多）卤代苯（C6H7-nXn-1）和（多）卤代联苯（ -nXn-1-C6H5）作为主要产品。除了这些产品之外，三联苯是通过形成的卤代联苯的连续苯基化产生的。只有当通过 2-氯联苯的途径成为可能时，多氯苯才会形成相应的三联苯；然而，多溴苯可以通过中间形成的任何异构溴联苯产生三联苯。还显示通过氯原子的间迁移发生异构化的程度要小得多。

  Granular poly(arylene sulfide) is recovered from a slurry comprising granular poly(arylene sulfide), polar organic solvent, alkali metal halide, poly(arylene sulfide) oligomers, untreated reactants in the water by heating the slurry under conditions to evaporate polar organic solvent, water and volatile impurities at a temperature below the normal boiling point of the polar organic solvent to produce a dry mixture containing poly(arylene sulfide), poly(arylene sulfide) oligomers and alkali metal halide which is then reslurried with water to produce a reslurried mixture containing aqueous alkali metal halide solution and dispersed poly(arylene sulfide) oligomers with the reslurried mixture being filtered through a coarse screen to recover granular poly(arylene sulfide) thereon and pass a filtrate containing poly(arylene sulfide) oligomers and aqueous alkali metal halide solution therethrough. The filtrate can be further treated by filtering through a filter aid coated vacuum filter to recover poly(arylene sulfide) oligomers thereon and pass an aqueous alkali metal halide solution therethrough as filtrate.
