Abstract
The spectrophotometric monitoring of ozone consumption in a liquid phase is used to study the kinetics of cyclopentanone and methyl butyl ketone oxida tion. The rate of ozone reaction with ketones (RH) at 303-344 K in acidic ( HClO4) aqueous solutions is described by the equation w = k(1)[RH][O-3] + k (En)[RH] [HClO4], where k(1) is the rate constant for the reaction of ozone with RH and k(En) is the rate constant for the enolization of RH. The kine tic parameters of the process are found.
