Abstract
2-hexanoyl-5-(2-hydroxy 2-propyl)furan (HHPF), has been investigated as the principal product of radiolysis of 2-hexanoyl-furan (HF) in 2-propanol. The effect of absorbed dose on the product yields has been examined. Possible mechanisms for the formation of radiolytic products are discussed.
Abstract
The principal products of radiolysis of 1-(2-furanyl)-1-pentanone (FP) in 2-propanol in the presence of atmospheric oxygen were determined using a gas chromatograph coupled with a mass spectrometer. The principal products detected were:1-[2-(5-hydroxy-4-hydro) furanyl]-1-pentanone (HHFP), and 1-[2-(5-hydroxy-4-methyl) furanyl]-1-pentanone (HMFP).The radiation yield G has been determined and mechanisms for the formation of the radiolytic products are proposed.
Abstract
Hydrogen and methane produced during the 
-radiolysis of 2-propanol have been measured in the absence and presence of 0.1 and 0.01 M ketone (1-(2-furanyl)-1-hexanone) at different doses. In the absence of ketone at 100 kGy, the hydrogen and methane yields were found to be G(H2)=5.1 and G(CH4)=2.02. At lower ketone concentrations the hydrogen and methane yields were G(H2)=4.35 and G(CH4)=1.83, while higher concentrations decreased the above values to G(H2)=2.95 and G(CH4)=1.33, respectively. The radiolytic mechanism is discussed in detail.
Abstract
Gamma radiolysis of 2-acetylfuran (AF) in 2-propanol, in absence of atmospheric oxygen, has been investigated. The radiation yields of hydrogen, methane at different doses as well as radiolytic products in solution were determined. The radiolytic products were determined by gas chromatography coupled with mass spectrometry. The mechanisms for formation of detected radiolytic products and the effect of (AF) concentration on hydrogen and methane yields are discussed.
