Radiation-chemical transformations in naphthalene aqueous solutions

Gas-liquid chromatography method has been used to.show that, following γ-radiolysis of naphthalene aqueous solutions under stationary conditions, naphthalene consumption obeys a kinetic equation of the first order with a rate constant k=(6.05+0.05)x10-3 s-1. 1- and 2- naphthols; 1.4-, 1.5- and 2.7-dioxynaphthalenes are found in the reaction products. A maximUm yield of the 1- and 2-naphthols does not exceed 10-15% of the reacted naphthalene quantity. Kinetics of the 1-naphthol accumulation in the initial period is describeb by equation of the second order k=(3.54+-0.03)x10-6 m3xmol-1xs-1; the yield of molecules for 100 eV of absorbed energy is G(NphOH)=1.6. The data obtained in the presence of additions are explained by a high reactivity of the naphthols and naphthalene in relation to OH, H and esub(aq) radicals and their competitions in the reactions with the radicals mentioned
