1. Process for preparing LiPF6 solutions in an organic solvent, or a mixture of two or more organic solvents, proceeding from PCl3, which is first reacted continuously in the gas phase with HF to form a PF3-containing reaction mixture which in turn is reacted continuously in the gas phase with Cl2 initially to form a PCl2F3-containing reaction mixture and with additional HF to form a PF5-containing reaction mixture, characterized in that the PF5-containing reaction mixture is finally reacted in a fixed bed reactor or fluidized bed reactor over LiF mouldings or with an LiF powder and/or an LiFxHF adduct, and the reaction product is washed with an organic solvent out of the fixed bed reactor or the fluidized bed reactor and isolated. |
