Rate constants have been determined for the reactions of SO4-with a series of alcohols, including hydrated formaldehyde. The SO, -radical was produced by the laserflash photolysis of persulfate, Sz02-. Rate constants for the reactions of SO4-with alcohols range from 1.0 x lo7 for methanol to 3.4 x 10' M-' s-l for 1-octanol. Rate constants for the reactions of SO4-with deuterated methanol and ethanol are lower by about a factor of 2.5. For methanol, ethanol, and 2-propanol, the temperature dependence of the rate constant was determined over the range 10-45°C.

Rate constants have been determined for the reactions of SO4-with a series of alkanes and ethers. The SO, radical was produced by the laser-flash photolysis of persulfate, SZO: -.
