Radiolysis of Liquid Propane: non-Radical Reactions
نویسنده
چکیده
The yields of ionic and excited molecule reactions in y-radiolysis of liquid propane from 35 to -130C have been assessed by isotopic analysis of C3Hs-l-C3Ds+Oz and CH3CD2CH3 -1-02 mixtures. From a comparison with gas phase data the following conclusions are reached for the gas to liquid phase change: (a) the ionic decomposition yield rlecreases by :5 69 %, (b) the net excited molecule decomposition yield decreases by 7 %or less, (c) parent ion fragmentation stm occurs in the liquid and exhibits fragmentation processes requiring from 1-4 eV excitation, (d) the H"2/Htransfer reaction ratio for Cz!-Il -IC3Hs seems to be increased, and (e) the isotopic decomposition of ClhCD2 CH3 is drastically changed.

Radiolysis of Liquid Propane: Radical Reactions
The radical reactions in the liquid phase y-radiolysis of propane have been studied from -130 to 35°C and compared with the gas-phase radiolysis at 35°C. Oxygen was used as a scavenger 10 separate thermal radical yields, and effects· of phase and temperature on the radical yields were assessed. The gas-liquid phase change (a) decreases total decomposition by about 14 %, (b) increMCs disproporti...
