The present invention concerns a process for producing a polyarylene sulfide of high whiteness from an alkali metal sulfide and a dihalogenated aromatic compound, wherein a reaction product obtained by reacting alkali metal sulfide (M²₂S) and at least one ingredient (M¹X) selected from the group consisting of alkali metal halide and alkaline earth metal halide under the presence of water and polar solvent and separating by solid-liquid separation are brought into contact with a dihalogenated aromatic compound.
本发明涉及一种用碱金属硫化物和二卤代芳香族化合物生产高白度聚芳硫醚的工艺,其中,在水和极性溶剂存在下,碱金属硫化物(M²₂S)和至少一种选自碱金属卤化物和碱土金属卤化物的成分(M¹X)反应得到的反应产物与二卤代芳香族化合物接触,并通过固液分离进行分离。
