Abstract
Monochlorophenols are smoothly oxidized to carbon dioxide and carbon monoxide when vapors in air are passed over fixed beds of municipal waste incinerator fly ash at 625-725 K. Simultaneously polychlorinated benzenes, monobenzofurans, and dibenzo-p-dioxins are formed with a large fraction of the original chlorine concentrated in these products. Fly ash catalyzed oxychlorination of phenol in the presence of HCl at 425-725 K resulted in the formation of chlorinated phenols which, in turn, were converted above 625 K into mainly CO 2 and the (poly)chloroarenes mentioned above. In contrast, under similar conditions, (chlorinated) benzenes are inert
