The Radiation Chemistry of the Aliphatic Alcohols^1,2

Gamma-radiolysis of the ethanol-water binary system in the presence of oxygen

“…The onset of studies of the liquid phase radiolysis of ethanol and other alcohols dates back to 1954 when McDonell and Newton [6] found that the main radi olysis products of anhydrous ethanol are hydrogen; acetaldehyde, a product of the disproportionation of two α hydroxyethyl radicals 2СН 3 СНОН → С 2 Н 5 ОН + СН 3 СНО, (1а) and 2,3 butanediol, their combination product Further studies were devoted to the formation mechanisms of reactive species in ethanol and their reaction kinetics and refinement of the values of prod uct yields, including those of transient products. The results of these investigations have been most compre hensively summarized in a review by Freeman [7].…”

Saturn's inner satellites: Ice chemistry and magnetosphere effects

“…For example, the G value for the processing of CH 3 CH 2 OH → CH 3 CHO (in the pure state) is 3.5 molecules/100 eV. G values and chemistry utilized here are from radiolysis experiments of the materials in the liquid or solid phase only, and are from the following references: Basson [1969], Myron and Freeman [1965a, 1965b], Ramaradhya and Freeman [1961], Imamura et al [1963], Hayon and Weiss [1961a, 1961b], Theard and Burton [1963], Silaev et al [1979], McDonnell [1955], McDonnell and Gordon [1955], and McDonnell and Newton [1954]. Ketene chemistry (CH 2 CO and HCCO) is from Boullart et al [1994] and Carl et al [2001].…”

Aging of wines and other spiritous products, acceleration by physical treatments

“…In the presence of oxygen the yield of these products was 150 per cent or more of these yields and peroxy and acidic products totaling 25 molecules/100 ev were produced (Bakh and Sorokin, 1955). McDonell (1951) and McDonell and Newton (1954) studied the radiation chemistry of alcohols including ethanol. Products of radiolysis of ethanol included the products mentioned above as well as 2,3-butylene glycol and hydrocarbons including unsaturated compounds particularly ethylene.…”
