ABSTRACT:
A method for working up antimony halide catalysts containing inactivating organic impurities having high boiling points, in which anhydrous antimony trichloride can be isolated in a technically simple manner. The antimony trichloride can be chlorinated to obtain antimony pentachloride which can be re-used as a catalyst in a fluorination process.
