ABSTRACT:
The present invention provides a method of recovering a lithium chloride, which comprises reacting a dihalogenated aromatic compound and an alkali metal sulfide and/or alkali metal hydrogen sulfide in a polar solvent under the pressure of lithium chloride, separating a solvent insoluble component from the resultant reaction mixture to obtain a solution, and calcinating a residue obtained by removing volatile substances from the resultant solution, as well as a method of recovering a lithium chloride, which comprises reacting a dihalogenated aromatic compound and an alkali metal sulfide and/or alkali metal hydrogen sulfide in a polar solvent under the pressure of lithium chloride, separating the granular polymer ingredient from the resultant reaction mixture subjecting the liquid suspension obtained by said separation to solid-liquid separation and calcinating the residue obtained by removing volatile substances from the resultant solution component.
