Abstract

A laser photolysis-long path laser absorption (LP-LPLA) experiment has been used to determine the rate constants for H-atom abstraction reactions of thedichloride radical anion (Cl2-) in aqueous solution. From direct measurements of the decay of Cl2-in the presence of different reactants at pH= 4 and I= 0.1 M thefollowing rate constants at T= 298 K were derived: methanol,(5.1±0.3)· 104 M-1 s-1; ethanol,(1.2±0.2)· 105 M-1 s-1; 1-propanol,(1.01 ...
