THE ROLE OF IONS IN THE RADIOLYSIS OF ORGANIC LIQUIDS
Irradiation to 3 x 10/sup 21/ ev/g of solutions of stannic chloride (SnCl/sub 4/) in toluene at 195 deg K by 1-Mev electrons gave oand m- and/or p- chlorotoluene yields (G, molecules/100 ev) which were unaffected by changes in temperature and dose andd by the presence of ethylene andd nitric oxide, but rose with SnCl/sub 4/ concentration to approach a limiting total value near 0.2. When ethylene was present, G(total C/sub 9/H/sub 12/) was near 0.01. When CCl/sub 4/ was substituted for SnCl/sub 4/, a different product pattern was found. Squalene was irradiated with Co/sup 60/ gamma rays at room temperature and with 1-Mev electrons at 243 deg K. The main radiation-induced effects, with their G-values at room temperature, are loss of unsaturation (4.8), crosslinking (1.35), trans- cis isomerization (0.83), andd hydrogen evolution (0.58). Most of the loss of unsaturation is attributed to cyclization; it occurs only in the crosslinked fraction. Increased yields (on the basis of energy absorbed in the solute) were trans-polyisoprene when these were irradiated in benzene solution. The chlorination of toluene and the cyclization of cross-linked squalene are believed to have ionic intermediates. (auth)
