Effect of temperature on the rates of reaction of excess electrons in liquid hydrocarbonsAt a l' radiolysis dose of 1X10 18 eV/g in ethanol at 296°K the hydrogen yields in neutral ethanol were G(H2) =5.0 at 1 bar and 5.5 at 5.3 kbar; in 1 mM and 1 M sulfuric acid G(H2) =5.7, independent of pressure. The electron scavengers nitrobenzene, acetone, and naphthalene reduce the hydrogen yields in neutral and acidic ethanol at 1 bar and 5.3 kbar; increasing the pressure greatly reduces the ease of scavenging the free ions but has only a small effect on scavenging efficiency in the spurs. Using as a standard the reaction esolv-->C2H50so1v-+H with k=1.2X10 6 sec-1 at 1 bar and t. emS/mole averaged between 0 and 5.3 kbar, one obtains the following values for k(M-l' sec-l) and t.vt (ems/mole): esolv-+Hsolv+' 2.8X 10 10 at zero ionic strength, +4.5; esolv-+CaH5N02, 1.5X 10 10 , +7.5; esolv-+naphthalene, 5.0X 10 9 , +5.6; esolv-+CHaCOCHs, 4.2X 10 9 , +5.1. The diffusion coefficient of solvated electrons in ethanol appears to correlate with the liquid viscosity; this is different from the behavior of electrons in alkanes. In ethanol t.Vtd;(fusion",,+7 emS/mole for esolv-and +4 emS/mole for H,olv+. The free ion yield in ethanol is G(e,olv-)fi=1.7, independent of pressure from 1 bar to 5.3 kbar; the model of Freeman and Fayadh U. Chem. Phys. 43, 86 (1965) ] is consistent with this behavior and it predicts that Gli in methanol and water are also independent of pressure.
