| titleOfInvention | Method of treating by-product salt yieled with polyarylene sulfide |
| abstract | There is disclosed a process for treating a by-product salt of a polyarylene sulfide which comprises subjecting solid matter containing an aprotic organic solvent and the by-product salt that is formed in the case of producing a polyarylene sulfide by polymerization condensation reaction of an alkali metal sulfide and a dihalogenated aromatic compound in the aprotic organic solvent to a drying treatment followed by a firing treatment of the resultant dryingly treated matter at a temperature in the range of 500 to 1000° C. The above process is capable of enhancing the solubility in water, of the by-product salt comprising sodium chloride as the principal component in the production of polyarylene sulfide, and affording waste water which is lowered in SS and COD in the case where the by-product salt is dissolved in water and is discharged as waste water. |
