Abstract:The sodium tetrachloroaluminate produced in the producing process of chlorodiphenyl phosphine (CDPP) was treated. Sodium chloride and aluminium chloride were separated using methanol. The recovered sodium chloride could be used directly in the decomplexing reaction. The recovered aluminium chloride was used to prepare polyaluminium chloride (PAC) with the same efficiency as the purchased PAC in water treatment. |
Key words:chlorodiphenyl phosphine; sodium tetrachloroaluminate; polyaluminium chloride |
