Radiation-Induced Reaction between Iodine and Heptane

Abstract

The radiation-induced reaction between iodine and n-heptane has been studied with a view to its use in the q.uantita.tive determination of free radical production in the radiolysis of liquid hydrocarbons. The yield of this reactIOn has been found to be nearly independent of iodine concentration and of temperature of the sample. The reaction is inhibited by the presence of dissolved oxygen. For each mole of hydrogen produced 0.6 mole of iodine is absorbed which indicates that free radical production is a major component of th~ over-all process. The primary decomposition yield is of the order of 10 bonds broken per 100 ev of absorbed energy.

Radiation Chemistry and Hot Atom Chemistry

“…Photolysis of C2H51 in paraffin oil yielded H2• C2H4, C2Hs. The x-ray induced reactions of solutions of 12 in n-C7H 16 have been studied by Forsyth, Weber & Schuler (157) for the primary purpose of determining the useful ness of 12 in the determination of free radical production in liquid hydro carbons. When deuterated CSH14 was the solvent 20 per cent of the hydrogen was HD.…”

Iodine–paint interactions during nuclear reactor severe accidents

“…Under irradiation, iodine reacts with polymer radicals (PÅ) as shown in Reaction (1) (Ebert et al, 1965;Fessenden and Schuler, 1957;Weber et al, 1955;Williams and Hamill, 1950;Forsyth et al, 1954).…”

“…It has been shown indeed that an important part of chemical effects is due to radical reactions. 3 It can be shown that changes of irradiation conditions lead to a modification of the relative abundance of various reaction products.…”
