ABSTRACT OF THE DISCLOSURE 4-Fluorobenzophenone derivatives or 4,4'-difluoro- benzophenone are produced by effecting a halogen-fluorine exchanging reaction between the corresponding 4-halogeno- benzophenone derivatives or 4,4'-dihalogenobenzophenone and an alkali fluoride. The reaction is carried out by heating in an organic solvent. After distilling off the solvent from the reaction product mixture, the end product is isolated by extracting with a solvent. Alternatively the end product is isolated by distillation.
