FLUORINATED BENZENE MANUFACTURING PROCESS |
摘要 |
A process is disclosed for producing fluorinated benzene. The process involves (a) contacting chlorobenzene starting material with a metal fluoride composition of the formula (AgF)(MF2)x (where M is Mn, Fe, Co, Ni, Cu, Zn or a mixture thereof and x is a number between 0 and 1) at a temperature above 175 DEG C sufficient to remove the chlorine substituent from the starting material and to transfer F from the metal fluoride composition to the starting material (thereby producing a reduced metal fluoride composition comprising a silver component of the formula AgF1-y where y is a number from 0.01 to 1); (b) oxidizing the reduced metal fluoride composition from (a) in the presence of HF to regenerate the metal fluoride mixture composition of the formula (AgF)(MF2)x; and (c) recycling regenerated metal fluoride composition of (b) to (a).
