Radiolysis of dilute oxygen-free hexane aqueous solutions give dodecanes isomers analyzed by capillary gas chromatography.The relative yields for radicals which react by radical-radical recombination reactions are 39 percent, 32 percent and 29 percent for primary hexyl radical, secondary-2 hexyl radical and secondary-3 hexyl radical respectively.This distribution is changed with the N2O saturation before the radiolysis to 22 percent, 42 percent and 37 percent.If the first distribution is statistic, the increase of OH. available to attack the solute gives the distribution existing in pure alkane radiolysis.
Radiolyse des alcanes en phase liquide: nouvelles evidences experimentales et nouveau schema radiolytique

Yields of final products (dimers) from the radiolysis of n-hexane and 2,3-dimethylbutane are studied by capillary chromatographic techniques for trace analysis.Reaction of intermediates with the products, the alkane molecules or impurities, is reduced by using low dose (1 kGy), low temperature (195 K) and high dose rate (LINAC).Temperature is the most important experiment variable; by reducing the temperature, reactions with sgnificant activation energies do not compete with radical-radical termination reactions.Products from LINAC radiolysis provide information about active species (reactive fragment, allylic radical...) which deserve a more detailed examination by direct methods.
