Popis:	The LaMnO 3+ δ perovskite shows interesting performances in the total catalytic destruction of chlorinated C 2 hydrocarbons selectively to CO x (mainly CO 2 ) and HCl. It is shown that the unsaturated molecules are more difficult to destroy than the saturated ones. The saturated chlorinated C 2 hydrocarbons are readily converted to their unsaturated equivalent by an unimolecular elimination reaction probably catalysed by Lewis acid sites. The formation of higher chlorinated C 2 by-products can be explained by successive chlorination and dehydrochlorination reactions. Addition of water favours the destruction by decreasing the amount of chlorinated by-products and results in an enhanced carbon oxides formation. Oxygen must also be present to prevent the destruction of the active LaMnO 3+ δ oxygen overstoichiometric structure.
