Abstract
Abstract Gamma-radiolysis of furyl ketones in 2-propanol is studied. The irradiated solutes 1-(2-furyl)-1-pentanone (I) and (2-furyl)-phenylmethanone (II) were synthesised in the laboratory. Apart from gaseous products (e.g. H 2 , CH 4 ), irradiation leads, in both cases, to the formation of homologous substitution, radioreduction and dimerisation derivatives. The radiochemical yields of hydrogen and methane are lower than those obtained with pure 2-propanol. The yields of the main products formed during radiolysis of ketones (I) and (II) decrease then become stabilised as the dose adsorbed increases. Concerning the mechanism, electron capture and radical processes are probably at the origin of the alcohols and pinacols which are produced by radioreduction and dimerisation respectively; substitution products indicate radical processes.
