    摘要: In a process for producing a polyarylene thioether having high stability by dehalogenation/sulfurization reaction of an alkali metal (M) sulfide such as sodium sulfide and a dihaloaromatic compound such as paradichlorobenzene in a polar organic solvent, the haloaromatic compound is used excessively in an appropriate range rather than the alkali metal sulfide and the latter stage of the reaction or all period of the reaction is conducted under a powerful stirring condition to a certain degree to obtain the polyarylene thioether wherein the concentration of --SM or --SH groups of the polymer terminal is lowered. The polyarylene thioether thus obtained suppresses the coloration in the processing with an apparatus made of ferrous material such as extruder.

    摘要: A fluidized-bed activation furnace for activated carbon is disclosed. The furnace is provided with a central hollow pillar having an outlet for discharging activated carbon granules at the upper portion thereof, a bowl-shaped cap covering the top portion of the central hollow pillar and a perforated plate fixed to the outer periphery of the central hollow pillar below the outlet for discharging activated carbon granules. After the granules of carbon are activated while a fluidized-bed is formed of the activated carbon granules, the substantially whole amount of granular activated carbon is discharged in a short time maintaining a high temperature.
