Abstract
A process for preparing hexachlorocyclopentenones comprises passing gaseous oxygen through hexachlorocyclopentadiene at a temperature between about 40 DEG and 300 DEG C. In a modification of the process a hydrolyzation agent, e.g. water or sulphuric acid, is incorporated in the reaction mixture and pentachloropentadienoic acid is recovered as the product. Elevated pressures and catalysts, e.g. benzoyl peroxide and ultraviolet light may be employed in the process. Examples I-IV relate to the preparation of the mixed hexachloro-2 and -3 cyclopentenones, the products being resolved in Example I. Example V relates to the preparation of pentachloropentadienoic acid.
