Termination of •CH2OH/CH2O•- Radicals in Aqueous Solution

Authors: W. Wang, M. N. Schuchmann, Vinzens Bachler, H. Schuchmann, C. Sonntag Hydroxymethyl radical•CH2OH and its radical anion •CH2O- (pKa 10.7) were generated pulse-radiolytically in N2O-saturated aqueous solutions of methanol. The overall decay is by second-order kinetics. At pH ≤ 8 (•CH2OH, 2k = 1.7 × 109 dm3 mol-1 s-1), one observes ethylene glycol and formaldehyde plus methanol in a…
