Abstract
Spectrophotometry is applied to study the oxidation of ethylene glycol, tri
ethylene glycol, glycerol, etriol, pentaerithritol and mannitol by ozone in
aqueous solutions at 277-304 K. Rate constants and activation parameters o
f the reaction are measured. It is proposed that the oxidation of these alc
ohols by ozone occurs via the same mechanism. The formation of an intermedi
ate complex is a rate-limiting step in the case of diols; the decomposition
of the complex is a rate-limiting step for tri- to hexatomic alcohols.
