摘要：

Rate constants have been measured in aqueous solutions for the reactions of the carbonate radical, CO3.-, with several saturated alcohols and one cyclic ether as a function of temperature. Arrhenius pre-exponential factors ranged from 2 x 10(8) to 1 x 10(9) l mol-1 s-1 and activation energies ranged from 16 to 29 kJ mol-1. The results suggest that the reactions are not pure hydrogen abstraction, but involve an additional interaction of the radical with the -OH or -O- linkage.
