Abstract
A process for the removal of fluoride from a spent fluorination catalyst which has been used in a hydrofluorination reaction and which comprises chromia, halogenated chromia or chrominm oxyfluoride, the process comprising contacting the spent fluorination catalyst, of aqueous potassium hydroxide which has a concentration in the range from 25% w/w to 75% w/w.
