Data are reported from tests investigating the performance of the LaMnO sub(3+ delta ) perskovite in the total catalytic destruction of chlorinated C sub(2) hydrocarbons selectively to CO sub(x) and HCl. Findings from the project suggested that unsaturated molecules are more difficult to destroy than saturated molecules. Saturated chlorinated C sub(2) hydrocarbons are converted into their unsaturated equivalent fairly easily by an unimolecular elimination reaction that is most likely catalyzed by Lewis acid states. Generation of higher chlorinated C sub(2) by-products was strongly associated with the successive chlorination and dehydrochlorination reactions. Destruction processes benefit from the addition of water, which acts to reduce the quantity of chlorinated by-products.
